In wide chip interfaces like DDR, HBM and ONFI, it can be challenging to synthesize and connect high-frequency controllers to the PHY hard macros. Clock trees can be expansive, pushing tools to their limits, and often multiple clock domains are needed. Jitter can also be an issue on long paths. In this presentation Brian will show how True Circuits PLL and DLL IP is being used by multiple customers to build ONFI and HBM subsystems in advanced TSMC process nodes, and discuss the tradeoffs and timing budget concerns among different timing architectures. In addition, he will explain how source-synchronous signaling is used in our DDR PHY to ease timing closure, and to allow the memory controller to be synthesized for high-frequency operation, which reduces its size and lowers its latency. By using a soft IP "shim" between the memory controller and PHY, the memory controller only needs a single localized clock tree, reducing mismatch and jitter. The long routes between the soft shim and the PHY hard macros are source-synchronous, so data/strobe groups need only be roughly matched, something easily accomplished by place and route tools.

I wanted to know what's the best website that I can use for pdf to word. It will help me to understand what I'm doing wrong and I can fix all my documents. It's the only thing that I need right now. It's what they tell me too. - Kaylynn - Report As Inappropriate
I did not expect that anyone would see this But I am glad now everyone knows about this casino game. IT was a hoax really! - Kaylynn - Report As Inappropriate
Honestly this site  is so helpful that it could automatically just give me all on information i needed on the closure here along with another site here that i needed to know about, so thanks a lot for that !! - Robert - Report As Inappropriate
Some time we have to need the all update and secure the time value so here the best app for you get alarmsinwindows10 this is the full updated app to need you follow some tips for save the time. - Thanos - Report As Inappropriate
