Verification and AMS are top search terms on SemiWiki so clearly designers have a pressing need for fast and accurate verification of today’s mixed-signal SoCs that include massive digital blocks and precision analog/RF circuits. They need simulation performance to verify the mixed-signal functionality, and they need nanometer… Read More
Cadence sets the Global Standards in VIP for AMBA based SoC
We have shown in Semiwiki how strong Cadence position was in Verification IP (VIP) in a previous post focusing on Interface standards like SuperSpeed USB or PCI Express. But IP based functions are used everywhere in a SoC, not only to interface with the external world, and need to be verified, as well, like for AMBA based functions.… Read More
Next Generation FPGA Prototyping
One technology that has quietly gone mainstream in semiconductor design is FPGA prototyping. That is, using an FPGA version of the design to run extensive verification. There are two approaches to doing this. The first way is simply to build an prototype board, buy some FPGAs from Xilinx or Altera and do everything yourself. The… Read More
Why are AMS designers turned off by Behavioral Modeling?
Analog Mixed-Signal (AMS) behavioral models have not caught on with the AMS designer community. Why? I suspect a significant reason (but certainly not the only one) is the way they are presented.
First, what is AMS behavioral modeling?
I define it as “a set of user-defined equations that decribe the terminal behavior of a component”.… Read More
Static Timing Analysis for Memory Characterization
Modern SoC (System On Chip) designs contain a larger number of RAM (Random Access Memory) instances, so how do you know what the speed, timing and power are for any instance? There are a couple of approaches:

TSMC Financial Update Q4 2012!
The weather in Taiwan last week was very nice, not too hot but certainly not cold. The same could be said for the TSM stock which broke $16 after the October financial report where TSMC reported a sales increase of 15% over September. Revenues for this year thus far increased 19% over last year so why isn’t TSM stock at $20 like I predicted… Read More
Smartphone Market Share
The numbers for smartphone sales in Q3 are starting to roll in. These are in units and not yet revenue (let alone profit) numbers although everyone down to Sony is for sure profitable. Samsung is running away with the volume, selling more than Apple, Huawei and Sony put together. One name that is missing is Motorola (Google) which … Read More
Carbon has Six Weeks of ARM, not to Mention Imagination and MIPS
As George E.P. Box said, “essentially all models are wrong but some are useful.” That is certainly the case with Carbon’s models. For processors they have two models, one that is fast (but not timing-accurate) and one that is accurate (but not fast). But both are useful.
Carbon attended the ARM TechCon in Santa… Read More
ICCAD at 30: Alberto Looks Back and Forward
At ICCAD earlier this week, CEDA sponsored a talk by Alberto Sangiovanni-Vincentelli looking back over the last 30 years (it is the 30th anniversary of ICCAD) and looking to the future. As is always the case in these sorts of presentations, the retrospective contained a lot more detail than the going forward part. Clayton Christensen… Read More
IJTAG, Testing Large SoCs
Test is the Rodney Dangerfield of EDA, it doesn’t get any respect. All designs need to be tested but somehow synthesis, routing, analog layout and the rest are the sexy areas. In my spoof all purpose EDA keynote address I even dissed it:You are short on time so slip in a quick mention of manufacturing test. Who knows anything … Read More
