The design of an SRAM array requires focus on the key characteristics of readability, writeability, and read stability. As technology scaling has enabled the integration of large (cache) arrays on die, the sheer number of bitcells has necessitated a verification methodology that focuses on “statistical high-sigma” variation… Read More

Webinar: A Tool for Process and Device Evaluation
Not only are foundries continuing to introduce processes at new advanced nodes, they are frequently updating or adding processes at existing nodes. There are many examples that illustrate this well. TSMC now has 16FF, 16FF+ and now 16FFC. They are also announcing 10nm and 7nm processes. In addition, they are going back to older… Read More
SystemC and Adam’s Law
At DVCon I sat in on a series of talks on using higher-level abstraction for design, then met Adam Sherer to get his perspective on progress in bringing SystemC to the masses (Adam runs simulation-based verification products at Cadence and organized the earlier session). I have to admit I have been a SystemC skeptic (pace Gary Smith)… Read More
What SOC Size Growth Means for IP Management
Whether or not in the past you believed all the of rhetoric about exploding design complexity in SOC’s, today there can be no debate that SOC size and complexity is well beyond something that can be managed without some kind of design management system. As would be expected, development of most larger designs relies on a data management… Read More
Analog Mixed-Signal Layout in a FinFET World
The intricacies of analog IP circuit design have always required special consideration during physical layout. The need for optimum device and/or cell matching on critical circuit topologies necessitates unique layout styles. The complex lithographic design rules of current FinFET process nodes impose additional restrictions… Read More
Can Qualcomm avoid repeating Motorola’s fate?
NPR had an interesting guest this morning: Edward Luce, author of “Time to Start Thinking: America in the Age of Descent”. I’m not about to turn SemiWiki into a politics blog, but there is some precedent in the technology business. I’ve caught myself saying more than once recently that “Motorola is no longer the company I worked 14… Read More
Custom IC Design Flow with OpenAccess
Imagine being able to use any combination of EDA vendor tools for schematic capture, SPICE circuit simulation, layout editing, place & route, DRC, LVS and extraction. On the foundry side, how about creating just a single Process Development Kit (PDK), instead of vendor-specific kits. Well, this is the basic premise of a recent… Read More
VC Apps Tutorial at DVCon 2016
We might wish that all our design automation needs could be handled by pre-packaged vendor tool features available at the push of a button, but that never was and never will be the case. In the language of crass commercialism, there may be no broad market for those features, even though you consider that analysis absolutely essential.… Read More
Attending DAC in Austin for Free
I love getting a good deal, and free is always compelling, so how about attending DAC in Austin for free this year? Sound too good to be true? Thanks to the generosity of three EDA companies – ATop Tech, ClioSoft and OneSpin, now you can can attend parts of DAC for free by registering here. This is now the 8th year that the I LOVE DAC… Read More
Software-Driven Verification and Portable Stimulus
I was at every single lunch at DVCon, not because the food was that great (it wasn’t bad) but because the topics were all interesting. The Wednesday lunch, hosted by Cadence, was a panel on software-driven verification and portable stimulus, moderated by Frank Schirrmeister (a different role for Frank – he’s usually a panel member… Read More
