Scan company ssn

hello my name is peter orlando and i'm from siemens eda and i'm here to talk to you about a future ready dft tescent streaming scan network the complexity and large desi system on the chip designs present many challenges affecting the design for test implementation efforts as well as manufacturing test costs test streaming scan network ssn for short is a true soc dft solution that addresses these challenges by decoupling core level and chip level dft in this session you will learn about why the industry is adopting ssn in the transit in the transition to package scan and how ssn foundation foundational to fut is foundational to soc dft requirements first let's start with a few problems that ssn starts to address on the top left you'll see the linear linear bottom-up flow and also an iterative operation optimizations both of these are the type of techniques that you will see during development most of us have seen bottom-up flow or linear flow where you take the time to address what the needs are for your design your dft and you implement without any changes without any kind of accommodations that appear throughout the development cycle for that reason for this kind of flow you will see some bandwidth or wasted bandwidth related to those decisions because you're not able to take the most optimal decision at time and adjust for any changes that may occur for example during design time right you'll have to decide which core you're going to test in parallel similar with the bottom left picture looks like you need to decide which of those chords you will test in will test concurrently which will force you to choose the scan chain length for each of these which goes to talks to the core to core dependencies so that when you have uh some some kind of scan chain lengths that are different lengths then you're going to have um additional padding added to those to those cores during retargeting and as the designs grow those complexities continue to grow okay and then as you can take this bottom up flow this iterative flow you can adjust for any changes design changes that may occur and kind of optimize that but that takes time okay you may not have that in your schedule another complexity that we aim to solve with ssn is the shift speed the shift speed has largely been been limited by long signals and with ssn we we aim to solve that by taking the problem closer to the course okay and i'll explain i'll explain a little bit how we do that broadcasting with tiles is difficult as well that we we we've tried to solve because you have tiling which requires you to have programmable pipeline stages to get from the edge of the design to the tiles and again if you've you you've created this type of pad muxing that allows you or forces you into...
