Gate Level Aging min

Our laptops and desktop computers have billions of transistors in their application processor chips, yet I often don’t consider the reliability effects of aging that the transistors experience in the chips. At the recent Synopsys User Group (aka SNUG), there was a technical presentation on this topic from Srinivas Bodapati,… Read More

64Mb SRAM example, memory IP

Looking at a typical SoC design today it’s likely to contain a massive amount of memory IP, like: RAM, ROM, register files. Keeping memory close to the CPU makes sense for the lowest latency and highest performance metrics, but what about process variations affecting the memory operation? At the recent DAC conference held… Read More


Unexpected Help for Simulation from Machine Learning

Unexpected Help for Simulation from Machine Learning
by Tom Simon on 02-13-2018 at 12:00 pm

I attend a lot of events on machine learning and write about it regularly. However, I learned some exciting new information about machine learning in a very surprising place recently. Every year for the last few years I have attended the HSPICE SIG dinner hosted by Synopsys in Santa Clara. This event starts with a vendor fair featuring… Read More

The world is a risky place, according to Scott Wedge, Principal R&D Engineer at Synopsys, who presented at the Synopsys HSPICE SIG on Feb 2[SUP]nd[/SUP] in Santa Clara. Indeed, the world circuit designers face can be uncertain. Dealing with risk and departure from ideal was a main theme in the fascinating talks at this dinner… Read More

One of the things that I miss most about attending trade shows like DAC in the old days was that you actually got to see EDA tools being demonstrated live in the exhibit area. You could see what the GUI looked like, how the dialogs worked, and learn what kind of control you could have during analysis. Most of what you see today at DAC in the… Read More


Drift is a Bad Thing for SPICE Circuit Simulators

Drift is a Bad Thing for SPICE Circuit Simulators
by Daniel Payne on 10-07-2016 at 12:00 pm

My first job out of college was with Intel, located in Aloha, Oregon and I did circuit simulations using a proprietary SPICE circuit simulator called ASPEC that was maintained in-house. While doing some circuit simulations one day I noticed that an internal node in one of my circuits was gradually getting higher and higher, even… Read More

Synopsys’ New Circuit Simulation Environment Improves Productivity — for Free
by Pawan Fangaria on 02-07-2016 at 12:00 pm

When technology advances, complexities increase and data size becomes unmanageable. Fresh thinking and a new environment for automation are needed to provide the required increase in productivity. Specifically in case of circuit simulation of advanced-node analog designs, where precision is paramount and a large number… Read More


Circuit Simulation Update from #52DAC

Circuit Simulation Update from #52DAC
by Daniel Payne on 07-08-2015 at 12:00 pm

Actual users of circuit simulators told their design and simulation stories at DAC during a luncheon sponsored by Synopsys on June 8th. I always prefer to hear from a design engineer versus a marketing person about what tool they use for circuit simulation, and how it helps them analyze their design goals. This year there were engineers… Read More
