SPICE Model Generation using Machine Learning

SPICE Model Generation using Machine Learning
by Daniel Payne on 02-05-2017 at 10:00 pm

AI and machine learning are two popular buzz words in the high-tech daily news, so you should be getting used to hearing about them by now. What I hadn’t realized was that EDA companies are starting to use machine learning techniques, and specifically targeted at the daunting and compute intensive task of creating SPICE models… Read More


CEO Interview: Rene Donkers of Fractal Technologies

CEO Interview: Rene Donkers of Fractal Technologies
by Daniel Nenni on 11-28-2016 at 7:00 am

Fractal is another one of those very successful emerging EDA companies that you don’t read a lot about, except on SemiWiki. Rene Donkers is co-founder and CEO of Fractal Technologies, a company addressing IP quality assurance. This is a niche in the SoC tooling market that deserves some justification. Why not use an IP as-is… Read More


Can one flow bring four domains together?

Can one flow bring four domains together?
by Don Dingee on 10-28-2016 at 4:00 pm

IoT edge device design means four domains – MEMS, analog, digital, and RF – not only work together, but often live on the same die (or substrate in a 2.5D process) and are optimized for power and size. Getting these domains to work together effective calls for an enhanced flow.

Historically, these domains have not played together … Read More

Circuit Simulation Videos Show How To
by Daniel Payne on 10-13-2016 at 4:00 pm

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


TSMC and Solido to Share Experiences with Managing Variation in Webinar

TSMC and Solido to Share Experiences with Managing Variation in Webinar
by Tom Simon on 09-10-2016 at 7:00 am

TSMC knows better than anyone the effect that variation can have at advanced process nodes. Particularly in memory designs and in standard cell designs, variation has become a very critical because of its effects on yield and because of the high-cost of compensating for it. Smaller feature sizes combined with lower voltage thresholds… Read More


Are Your Transistor Models Good Enough?

Are Your Transistor Models Good Enough?
by Daniel Payne on 08-16-2016 at 12:00 pm

SoC designers can now capture their design ideas with high-level languages like C and SystemC, then synthesize those abstractions down into RTL code or gates, however in the end the physical IC is implemented using cell libraries made up of transistors. Circuit designers use simulation tools like SPICE on these transistor-level… Read More


It’s Time to Put Your Spice Netlists on a Diet

It’s Time to Put Your Spice Netlists on a Diet
by Tom Dillinger on 06-28-2016 at 7:00 am

Spice circuit simulation remains the backbone of IC design validation. Digital cell library developers rely upon Spice for circuit characterization, to provide the data for Liberty models. Memory IP designers utilize additional Spice features to perform statistical sampling. Analog and I/O interface designers extend these… Read More


The Emerging Importance of Parallel SPICE

The Emerging Importance of Parallel SPICE
by Tom Dillinger on 05-15-2016 at 7:00 am

SPICE simulation is the workhorse tool for custom circuit timing validation and electrical analysis. As the complexity of blocks and macros has increased in advanced process nodes — especially with post-layout extraction parasitic elements annotated to the circuit netlist — the model size and simulation throughput… Read More


Process Development, CAD and Circuit Design

Process Development, CAD and Circuit Design
by Daniel Payne on 04-29-2016 at 7:00 am

Working at Intel as a circuit designer I clearly remember how there were three distinct groups: Process Development, CAD and Circuit Design. Each of the groups sat in a different part of the building in Aloha Oregon, we had different job titles, different degrees, spoke with different acronyms and yet we all had to work together … Read More
