Sign Vermont Assignment of Partnership Interest Computer

Document type sign assignment of partnership interest connecticut simple

hello everyone thank you for attending today's webinar on hyperlinks correct model assignments for hyperlinks si hopefully you will learn today how to assign simulation models in hyperlinks lines and board sim so hopefully most of you are familiar with what hyperlinks signal integrity allows us to do is check our boards and pre layout schematics for potential signal integrity issues and this is a very valuable thing to do unfortunately the only problem we have with this is you really have to make sure your model assignment is accurate as possible in order to get real-world results in the simulation environment so it's very important to be able to understand what types of models we can use and how to properly assign those to our components either in our pre layout schematic or in our post layout board file brought in from any of your PCB CAD tools okay and then after that we're going to talk about how to save our model assignments okay we can actually use hyperlinks to automatically assign models to components in future simulation environments okay so this can be really cut down your time so you don't have to always if you're using the same component always map in that Ibis model or that spice model or that EBD model that you're trying to use for that particular component so this webinar is hosted by Oasis sales my name is Kyle lake I'm an application engineer

that but if you have any questions please let me know and if it's relevant to what I'm talking about now I'll definitely dive into it otherwise I condensed we get to you after the webinar has wrapped it okay so without further ado let's actually hop in to talking about how to correctly assign models for hyperlinks si okay well before we hop into that actually I just want to make sure that everyone's kind of clear on what Oasis sales and try logic can really offer you in the way of electronic design and simulation through Mentor Graphics so these are all the products that we both cover through the Mentor Graphics portfolio and that is first off I'll talk about expedition PCB so that is a very powerful enterprise level solution for printed circuit board design very capable very robust tool that allows for high end data management capabilities as well as concurrency through our different teams okay pads also a very well capable tool for printed circuit board design it allows us to really complete some very complex designs without having all the enterprise wrap around for data management collaboration or things like that what we're going to be focusing on today is hyperlinks and I'm assuming that most people are at least familiar with hyperlinks today but if you're not if hyperlinks is a family of simulation tools okay so hyperlinks includes signal integrity which we'll be talking about today power integrity for BC drop as well as AC analysis on your voltage planes there is hyperlynx DRC which is a graphical emi rule checker to make sure that your boards aren't going to be having too much EMI or causing issues like that okay as well as there are some analog solutions within the high points family as well and on kind of the manufacturing side of printed circuit board design we have valor so what valor allows us to do is manufacturing and assembly checks on the board level and get those fix as early as possible in the design cycle and increase your yield in manufacturing okay so how do we model ICS in hyperlinks aside and I'm assuming most people are at least familiar with Ibis models kind of are but Ibis models are behavioral models that model the analog behavior of i/o buffers okay so these are really what we are going to be using predominantly in the hyperlinks si flow in order to accurately simulate our drivers receivers in order to get that rise and fall time through the interconnect that we're trying to design okay so these are an industry standard typically they're created by the silicon vendor and that I always get the question on where do I get this Ibis model where is the best place to find Ibis models and 99% of the time you can go directly to the vendor and they should have those silk um for those Ibis models provided for the component that you use them okay so if you're not able to find that we do have the ability to manually create those but so the silicon vendors actually passed these tests in order to create these Ibis models okay so they're created by simulating spice models of the i/o buffers at different spice test bench levels and so it's really again an Iblees standard industry standard that models the actual inner workings of your components in order to use in simulation so like I said before it's very important in order to have accurate simulation results to use correct models as well as models that have been verified by those vendors okay so that's definitely about the best space to work in for those models all right another type of model that we can use to model different types of components on the board are EDD okay so what EVD models are are essentially an electrical board description so the best example that I have of this is a dim module so if we're purchasing a dim module typically that vendor will have already provided this EBD model it's essentially a black box description of that module so they have already passed validation of the signal integrity effects for that particular dim module and then we are able to plug that into our system and have it as part of our printed circuit board design that we can simulate okay so the only really remaining unknown that we have with EBD models is how it is going to react with our system the vendor selling the DIMM module should have already validated the signal integrity effects of their doom module okay so that's the EBD is a black box very easy to plug into simulations and work with and accurately model that DIMM module in your system okay so when we do get models it's important to understand kind of what they're made up of as well as kind of verify them to make sure that there's no sin tax lawyers or any pin mapping errors for example and within the hyperlinks si space we have the visual Ibis editor this actually allows us to open up an Ibis model which is essentially just a bunch of text that describes the pins which describes the clamp dials which describes the CMOS effects of those ICS that were using okay so i'll show how we can actually use that visual ibis editor to check for syntax numerical errors and then we can actually just simulate those and lines them very quickly to make sure that they're going to work how we believe that they should work okay so I haven't seen any questions yet but that's fine I just wanted to remind everyone that there is that chat box being GoToMeeting in order to ask questions and also get to those while we're discussing okay so a signing model so very easy process within the line sim environment so if you're unfamiliar with lines them I'll walk through this after we describe it a little bit we have the ability to draw an interconnect on the line some environment lines sim is that pre layout what if signal integrity environment where we can help design our interconnects the number of vias what layer is going to be routed on the trace width we can all play around with those types of characteristics to see how this signal is going to propagate down our printed circuit board okay very easy to assign models to this all you have to do is double click on the driver of the receiver and open up this assign dialog box so you'll see here on that picture I've got you one ten one and you one pintu and I need to assign models to that all I have to do is assign or click select when I have one of those pins click and navigate to the correct ibis model okay so within the Ibis model we can actually see the devices that make up that model you'll see we have library is an actual Ibis model the device or subcircuit that is defined in that Ibis model and then all the signals that are defined in that Ibis model as well and within the hyperlinks environment and Ibis models thanks to this we can assign on a per signal basis so you'll see we have a signal bin here or we can actually choose the pin of that device so you know that you're using pin 9 on your Virtex FPGA for example we can just assign that pin to use that correct pin modeling off of that Ibis model very easy to set that up okay on the flip side of that to assign models in the Boursin environment we first have to select a net and then click the assign models or edit values for the components and that opens up this exact same dialog box so whether we are assigning models in the line sim environment or in the board same environment it's the exact same process okay so that makes it a little bit simpler when we have to understand one dialogue box and how to use that okay so saving models like I said we go through this whole effort of first obtaining the Ibis models and then we go through and map which Ibis model goes to which component okay that's kind of a paint a time intensive process in order to assign those models correctly now we have the ability to actually save models in order to use them in future designs very very powerful way to quickly simulate with accurate Ibis model that - okay so the first thing is called a dot re f or reference file and what this does is it Maps models to icees based solely on reference designator okay so this is a powerful way to do it in a red vision type design cycle so if I am working on revision a of my board I can create a reference file and every time I see a you one or you two is automatically going to use this particular model okay so that's how a reference file works it all it does is map the Ibis model to the reference designator and that can be done in the pulldown of hyperlinks Fordson in models assigned models by reference as a thinner okay so that's kind of what the dialog box looks like for the reference month the reference file mapper all we have to do is select the reference designator and then select a model and save it to that our EF file okay so the next way and maybe the more powerful way is to actually use a qpi file or q PL file and what this does instead of using the reference designator it essentially just allows us to map models to part numbers okay so this is a much more powerful way to share mapping between project to project so if we're using the same FPGA the same yard ship anything like that we can assign that to the part number or part name and then use that in future designs okay so obviously reference designators are going to change the design of the design but part numbers or part names we might use that same part on ten different designs and we only have to assign that Ibis model once in order to accurately model that okay so I did want to talk a little bit about modeling packages and connectors so this is always another question of how to do this or it's difficult to understand how to do this and what we can do here is essentially use s parameters okay so I'm sure everyone's at least heard the term s parameters and what that allows us to do is very accurately model packages or connectors through our board ok so again these can be usually found from the vendor the connector vendors usually have models for this and all we have to do I will go through this process is assign a touchstone model touchstone as parameter almost synonymous there and it allows us to actually view the frequencies and the insertion loss of that s-parameter through the interconnect okay so here in the line same example I have down here we actually have an s-parameter port so you'll see I've dropped a s-parameter model and just double-click on there again to assign that touchstone model so you'll see this is a four port model here that's got port 1 and 3 on the left-hand side port 2 and 4 on the right-hand side and that's essentially all we had to do to accurately model this connector or a particular package that we want to take into effect our simulations we also have the ability to use SL M models which accurately model connectors as well and what we can do through there is everyone should at least be somewhat familiar with hyperlinks transmission line models and that's kind of that cylinder for a transmission line if you just double click on that it brings open the transmission line type properties and if you go down to the bottom left we can show connector and actually map it to those SLM models okay so that's typically kind of what semantic or other connector vendors will provide is an SLM model and it's very easy to incorporate it into our Haiphong system as well okay I think that's been enough slide again I don't see any other questions but that's totally fine so I'm going to hop into the actual hyperlinks demo and kind of play around with some model assignments to make sure everything's working correctly all right so this is hyperlinks this is just the start menu for for licensing purposes I'm just using a hyperlinks si gigahertz license okay so that is the high end hyperlinks license but I'm going to open up first a line sim freeform schematic okay so when I first openness this is our lying some environment again line sim is really powerful for interconnect design we can see that we have some drivers over here on the left hand side going through our interconnects we have a resistor transmission line we're modeling vias as well again another transmission lines layer changes and then we're actually ending up at our receiver here on the right-hand side okay so without any model assignment you can see that we on't have any models assigned to these components because we have question marks there all right so if I try and simulate this without actually assigning a model we're going to get an error when we're trying to simulate this so no IC output no driver so we can actually simulate which makes sense we're not giving it any response in order to simulate it with so in order to assign that model really easy I can just double click on any of these drivers or receivers here and this brings open up our assigned mile assign models dialog box okay so you'll see question marks for any component that does not have a model currently assigned to it okay so in order to do that I'm just going to hit on select and that opens up our select a model dialog box okay so for example here is most of what hyperlink ships with I've only added a few other Ibis models just to play around with but this is basically out of the box settings that we have for high-flying so these are all kind of what you currently have access to if you haven't gone down and downloaded any other Ibis models okay so for this I'm just going to quickly assign a vertex for we'll see that we have a vertex for device here and if I want I can choose by which signal name I want to model with or by which pen name pin number that is so I can select and hit OK alright so after I've done that it will see that u1 changes from that question marks to a actual green icon so to change if this is an input or output so some Ibis models allow pins to be input outputs some only input some only outputs but for example here we can see at the top at the buffer settings currently it's set to an input so if I hit OK here on you 170 you'll see that it kind of looks strange here because I didn't change that to an output so if I want I can just double click turn that back to an output and now it looks like a much more actual design here ok so in order to quickly assign the rest of these what I can do is I can hit copy and choose you 370 which is this other driver here and hit paste okay so that pastes those exact same settings to you 3 all right so that's easily done right there so now in order to assign the receivers I'm going to do the exact same process that we did right there and just to make it real quick I'm going to choose a general CMOS IO pen and hit okay alright so again this time we only see that it's an input so this particular signal is only an input signal so I can hit copy and hit paste on that u4 there and hit OK okay so that is how we assign those models in the line sim environment if I actually want to take a look and look at that Ibis model what I can do here is I can click this icon here which is edit Ibis I see models okay I believe in here we can also go to the models pulldown tab and click on the edit Ibis I see models okay so that opens up the visual Ibis editor that I was talking about earlier so what this allows us to do is if I want to go file open I can actually point to a particular Ibis model and these are just some models I threw in this to work with real quickly I'll just double click on this vertex for okay so if you're unfamiliar with the how Ibis models are made its again kind of a text file that essentially shows all of our different Drive strengths our pin our temperature thresholds our package delays we can see our parasitics here to find so there's a lot of stuff going on in this particular Ibis model so as soon as I open that up on the left hand side you'll actually see we have a little navigator that allows us to double click on our different models and pop down directly to that section so at the top we'll just have some disclaimers some notes from the manufacturer for example all right if I want I can actually expand these particular fields in our navigator ok so if I know I'm using this model of the LV TTL f2 we can actually look at our temperature range I double click there it pulls us down right to that section so this is a really good Ibis editor that allows us to learn kind of the anatomy of an Ibis model and understand what the model is going to actually look at ok so there's two things that I want to show in here and the first thing is if I click on this this is going to check for syntax errors within this particular Ibis model probably a good idea if you're working with a for the first time you get Nyhus model to run this through and click on the ibis spec conformance so that'll run through here and output any warnings or errors or cautions in the output window down there at the bottom okay so it's pretty important to look through here just to take a look to see if anything looks like we will not be able to use this model correctly okay so we can look at our different cautions and nothing really is standing out to say wow we really shouldn't use this model because it really doesn't look like it's set up correctly so airs are going to be syntax errors and if there's an error prevalent we will not be able to actually use that in simulation most likely it's going to run into a syntax error when we're actually simulating with this particular model so that's the first thing we want to do with the new Ibis models just to check to make sure that there's no glaring syntax errors that will not allow us to use it the next thing that we can actually do is look at the IV characteristics so if I click on my icon here on this graph this is actually viewing the Ibis data that is contained in information within this Ibis model okay so this opens up the Ibis data and we can see we have our component which model we're using I can click on all of these down pull down bars and I can actually look at the different models associated or assigned in this Ibis model then actually look at which signal as well okay so it gives us just some pin information the actual capacitance and voltage that's defined in this Ibis model so if you want to compare this to the datasheet really quickly just to make sure that we are on the right track this is an easier way to view this type of data and just going through the actual text data of the Ibis model okay so for some we can actually look at the power clamping diode the ground clamping diode we can see all of our IV characteristics for these different diodes so this is getting pretty far down in the IC and the actual how the IC is going to be working with these different clamp diodes okay so if I want I can look at a falling waveform a falling edge so again IV characteristics of this particular either model that we have chosen so those are the major thing the major benefits of using the Ibis editor so we can verify we can look in to the Ibis model and we can actually see the icy characteristics all right so now once I actually have the driver and receiver assigned now I can actually run a simulation without any errors very easy to go ahead and do that the next thing I want to talk about within the line sim environment before we go ahead and move on to the board sim is how to correctly assign those s parameter models that I was talking about so if I want I can add an S parameter to my schematic so that will pop open into the form of j1 okay so j1 just a random looks like a connector it might assume but nothing assigned to it yet all I have to do is double click on this and this will allow me to look towards a s parameter so unfortunately I'm not going to be covering today how to create s parameters in a hyperlinks environment we do have that ability but this is just allows me to point to an S parameter that we already have in our library okay so for example I'm going to use this example s for P okay so as soon as I click on it down there it actually shows us which ports are going to be placed onto the schematic all right so if I'll just hit OK that automatically puts port 1 and 3 on the left hand side port 2 and 4 on the right hand side so if I actually want to take a look at this a little bit stronger I can double click on this and hit you model file what this actually will bring up is the touchstone viewer okay so this will just take a second to instantiate and within the touchstone viewer it opens up what this model actually looks like so for right now I can look at the frequency response as well as the insertion loss I would like okay so this just kind of understands what the s-parameter model is actually modeling but what I want to do here this is just kind of general usage but now if I right-click on the actual model I can hit view connectivity this is very powerful because it actually allows me to see which port is connected to which port okay so this is allowing me to verify that that automatic port mapping was done correctly okay so if I click on port 2 or 3 you can see that those strong and weak settings are changing so if I'm looking at port 1 I can see that it's connected weakly to port 2 and 4 so weekly we can kind of consider that to be coupling of some sort okay but strong so we can see ports 1 & 3 are strongly connected through some sort of electrical connection ok so if I want to I got to make sure that 1 & 3 are connected and 2 or 4 connected so looking back at this automatic mapping we can see that that's not the case we have port 1 & 2 connected and port 3 & 4 connected so what I can do here is I can in the s-parameter assignment dialog box I can choose which ports are on which side so now I've got port 1 & 2 on the left-hand side port 3 & 4 on the right-hand side hit ok and now we have port 1 & 3 electrically connected or 2 & 4 electrically connected and if I want I can actually go ahead and assign use this in the in my simulation okay so to actually use an s-parameter in simulation we do have to connect this between transmission lines so for example I sign this pork I just have to drag that port to be connected there and there now I can actually use this s parameter in my simulation okay so what we've done here is a sign in s parameter we have validated that the S parameter connections are correct and now we've actually put it in our schematic so we can actually do simulation with it okay and we can see that just in putting that s parameter if I use this waveform viewer I can turn off those previous results so you can see that that s parameter has some drastic effects okay so that's all I'm going to talk about on the line chem environment let's hop into the origin environment I'm just going to go file close within this hyperlinks tool okay so now what I want to do is actually open up a board sim hyperlinks file okay so if you're unfamiliar with the board some environment this is essentially our PCB file they'll be brought in from any CAD tool so that can be in form of ODB + + which is typically the most recommended way that can be a cc file from expedition or it can be an Hyp file from any CAD tool now what that should bring in is our stack up editor so this is our entire stack up if I just look at this real quick this has a lot of our stack up information all of this should have been brought over from the CAD tool very important in signal integrity simulation for reference planes or dielectric constant very important in making sure that this information is correct okay so to actually go ahead and simulate within here again I'm not going to go into too much detail of what we can do with in the high flying environment but there is some powerful si capabilities that we can do we can just run an interactive simulation in that digital oscilloscope we can sweep different parameters that we have control over we have the ability to do a batch wizard across this entire design or some more high-end capabilities is running a DDR x simulation which runs it through kind of rder wizard and compares those two jeddaks standards we also have the ability to do Surtees analysis and channel analysis within hyperlinks okay so all of those sound great very powerful simulations that we can run but the most important thing before we run those simulations is ensuring that we have models assigned correctly okay so first I am going to look at my models and look at my library tags okay so this is where I can set the directories for my models that I'm able to use okay so if I want I can look here and look at my different library paths that I'm going to be looking at okay so if you're trying to assign an Ibis model and you can't find it for whatever reason go into here and just edit a new library mile path to point to a new folder okay so I can just add and browse to a folder with models in it and I can just hit select that folder and now we'll be able to actually point to that I this model very simple to do that okay so we'll also be talking in a little but this is where we're going to be pointing to our qualified part list file or qpl file and again qpl files assign Ibis models on a part number or part name basis okay so to first assign models to components i'm going to click on the select net name for SI analysis this dialog allows me to actually look at all of my different nets in this design okay so i can actually go ahead and filter all of these nets i can hit apply and that'll filter it for only nets that have data in the net name okay so if I select a net it'll kind of highlight that in the workspace and allow me to actually just see that particular net a little bit clearer what I can do here is I'm going to only work with 17 18 and 19 mm data 17 18 and 19 just to make this easy I'm just going to work with these three nets throughout a few designs to show how model assignment can work okay so again if I wanted to and I wanted to simulate these nets I selected them I hit this the oscilloscope icon and start that simulation but we haven't assigned any mob IC models yet so we obviously can't simulate this yet so there's no drive strength there's no receiver impedance assigned there's really nothing to simulate here without those models okay so now what I can do is with those three nets selected very important to remember that I can either go assign models by net in the models dialog pulldown or I can click on this icon here for assigning models or edit values for those components and this will pop open the different models that I have assigned for these components okay so we can see that r22 all these different resistors these are actually automatically defined just by the value that's been assigned to those parts in our CAD tool okay so that comes across correctly I'm the only thing that we would want to do here if it's ax if it's critical is to set parasitic okay so you can see here to set a parasitic we do have to use an Ibis model because those types of RLC parasitics can be defined in that Ibis model so again here I'm going to just work on you 30 and you 57 because those are the drivers and receivers that we're working with here okay so if you zoom in in the board stem tool we'll see you 57 here and the uther be over here is the receiver so I am going to select the model again and again I'm just for making it simple I'm going to use that vertex for ten nine one more time I work with that one fairly awesome and set that to my output model all right I'm going to again copy that and for every you 30 I'm just going to paste that here alright very easy we've already set the output now for you 57 I'm going to hit select and this time I'm going to use just a general IO 3.3 volt signal okay again very important to go to your manufacturer your vendor and get the Ibis model specific to your needs and if you need help with that please let me know I can hopefully help you point out point you to the right direction on that okay so now I'm going to copy that paste it to each other you 57s and there we go we've gone ahead and assigned those models for us alright so now that I've assigned those models what I can do to just kind of overlook all of the models that I've assigned in this particular design is if I go models manage assign models this show this is a very good dialogue box to become familiar with I think because it shows you then that name it shows you the pin name and it shows you any associated nets to that particular than that as well as the model that we've assigned towards it so this is really helpful in understanding what type of model is it's not input if it's an output what the part number is what Ibis model is it basically gives us all the information for modeling i this one particular dialog box all right so with that I'm just going to go ahead and run that simulation one more time and now that we've assigned the model it will run without error all right so again we can do a lot of stuff in here with simulation we can kind of figure out why there's some ringing maybe why there's some overshoot it may look like you can do that all within the hyperlinks environment and that's why setting up models is so critical and so important to make sure that's set up correctly right okay so now if I want to again look at that RAF file for reference reference designator model assignment and the qpl file for part number assignment that's all done through the models pulldown bar so you'll see we've got models we have in the second and third options here are assigned models and values by a reference designator and that part name okay so if I look at the reference designator for example this pulls up in the dialogue box that allows me to look at all of my different recipe reference designators in this design okay I have a few different things that I can do within here I can click on show only parts without models that's kind of nice to kind of filter this out this allows us to only see the components that don't have an assigned model with it currently okay I do want to point out that real quickly we have in our different ICS we do have the ability to do p ID models i'm not gonna be talking about this today this is only for power integrity analysis for either a voltage regulator model or a DC sync so let's just try and not look at that too much but we also have the IC models okay so as soon as I click on an IC model it gives us that reference designator it also gives us the part name of that reference designator okay so just like we had done in the select models dialog box I can browse to whichever type of model I want to and assign it to that I see okay and down below this actually shows us what the RAF file is made up of okay so we'll see that now we have this IC here that I just assigned to this Motorola Ibis model and we can see that it is the correct assignment that we just created so this is what the actual RAF file is made up of okay so very easy to do this I can just assign different models to it and there you go keep building this qpl saddle again qpl is for reference designator these can be used for revisions between boards or if you change some routing for example we can still use this RAF file with the same reference designators and automatically assign those models for it ok so to do that all I have to go here is go file and I can go save as and just save this as a detailed batch analysis re F and the way that we use this RTF file is to place it into your hyperlinks directory and it will automatically use that RTF mapping okay so just in the project directory of your current project of hyperlinks you're working with you place that RTF file there and it automatically uses it so that's an RTF file and if I wanted to I could actually take a look at that in just a text browser so I just open this up in a text browser and as you can see all it shows is reference designator and either value for those discrete components or if I scroll all the way down I think it's going to be at the bottom are you 32 you 33 you 34 you 35 up to you 40 are pointing to that ibis model okay so that's kind of what the anatomy of that RAF file looks like all right so now if I want to go to models assign models by part name QPL file this is definitely more powerful if I'm trying to exchange data between high Billings project and high Berlin's project if I'm using the same components on completely different printed circuit board designs this will still always assign the correct ibis model that I that I've assigned it towards in that simulation okay so again this is a really simple dialog box to get familiar with in the part type I can look at all these different part types that exist in my project so if I want I can look at my power ICS and look at only those ICS that have been assigned as power ICS or I can look at just mine capacitors and it actually gives us the different part names of those capacitors so if you know you're working with some sort of capacitor that we really really need to model the parasitics for I can actually just assign a value for that or I can actually select a model an Ibis model for those capacitors well for isyes all i have to do is drag a part number and select a an Ibis model for it so for this part name 224 LC is 5 2 SC anytime this is used in a future hyperlinks design it's going to automatically use the demo one that is component model 1 okay so as soon as I hit a sign you'll see that this qpl file is starting to get built up okay so really easy to again work with this by selecting those different part numbers okay so if I select these next ones I can just go ahead and start assigning different models towards them alright again once I've built this up I can go file save as and save this as a qpl file so I'm just going to call this Kyle board qpl file and again if I want to I can look in there at this with notepad plus plus and this time we're actually seeing instead of reference designators we're looking at it's an Icee it automatically knows that what part number it is any description this is just a blank description field that I didn't add anything in and then which Ibis model and which component of that Ibis model we're going to be using for those different part numbers okay alright so I think save that and again if I want to go to manage assign models we'll see that we have our different Ibis models that we just assigned okay so again I really think this dialog box is powerful really easy to work with as well all right so we've gone ahead and created our Ibis file or our qpl file and now i'm going to open up a different board and just point to that qpl file and automatically have those models assigned okay so to a point to that qpl file again we go to models and edit library paths edit model library paths here I can point to that QPL file just here so that's all we have to do in order to use that existing qpl file we've created I go here the add file and just navigate directly to it okay so there's that keel file just created a few minutes ago it opened and now it's automatically going to assign those models for us very easy to work with okay all right so all right so I don't see I see a few questions that I'm going to all respond to you directly but other than that that's all I was going to show today again thank you for attending today and here is my contact information one more time so if you have any questions on hyperlinks or just anything meant or related I'm always happy to help or get you the correct contact information of someone you can so thanks again for attending I hope you all have a great day
