Wally Rhines at #51DAC: EDA Grows From Solving New Problems

Wally Rhines at #51DAC: EDA Grows From Solving New Problems
by Paul McLellan on 06-24-2014 at 8:23 pm

Wally Rhines gave the keynote at DAC in 2004. One of the things that he pointed out ten years ago was that EDA revenue for any given market segment is pretty much flat once the initial growth phase has taken place and the market has been established. Incremental EDA revenue only comes from delivering new capabilities. Historically… Read More


An Update on Calibre at DAC

An Update on Calibre at DAC
by Daniel Payne on 06-09-2014 at 12:00 pm

Even though I live just 7 miles away from the Mentor Graphics corporate office in Oregon, I visited their DAC suite in San Francisco last week to get an update on Calibrefrom Michael White. The Calibre tools are used during IC verification and sign-off by performing DRC (Design Rule Checking) and LVS (Layout Versus Schematic).… Read More

My former co-worker, Kenneth Bakalar at Mentor Graphics is an expert in AMS modeling languages and UPFmethodology, so he recently teamed up with Eric Jeandeau to author an interesting white paper: Interpreting UPF for a Mixed-Signal Design Under Test. This white paper is based on a presentation made at DVCon earlier this year.… Read More

I was at EDPS in Monterey the last couple of days. It is one of the most interesting conferences to attend. Go next year since you already missed it this year. It is not big but the quality of the content is high. Historically the dinner in the middle is in the Monterey Yacht Club and there is a keynote speech. A few years ago it was me but this… Read More


Show Me How To Get Better DRC and LVS Results For My SoC Design

Show Me How To Get Better DRC and LVS Results For My SoC Design

Most IC engineers learn best by hands-on experience when another more experienced person can show us what to do. If you cannot find that experienced person, then the next best thing is a video from an expert. I was surprised to find out that video was so important today that the #2 most viewed web site on the Internet was www.youtube.comRead More

U2U: Things You Might Not Know About TSMC
by Paul McLellan on 04-10-2014 at 10:50 pm

At Mentor’s U2U this afternoon I attended a presentation on TSMC’s use of Calibre PERC (it is a programmable electrical rule checker) for qualification of IP in TSMC’s IP9000 program. I’ve written about this before here. Basically IP providers at N20SOC, N16FF, and below are required to use PERC to guarantee… Read More

Archaic tech metaphors abound, stuck in the psyche of users everywhere. We still “dial” numbers, long after the benefit of a short pull area code disappeared. (Humans could dial 1, 2, or 3 a lot faster on a rotary phone, and there were fewer dialpulses for central office switches to decode – thus big cities with more phone traffic like… Read More


Mentor Acquires BDA!

Mentor Acquires BDA!
by Daniel Nenni on 03-23-2014 at 7:00 am

Mentor Graphics acquired Berkeley Design Automation this morning. The details of the deal were unannounced. This is a strong move by Mentor to challenge Cadence and Synopsys in the nanometer analog/mixed-signal market and nanometer memory characterization market, respectively. Mentor not only acquires the technology and… Read More


Speeding Up AMS Verification by Modeling with Real Numbers

Speeding Up AMS Verification by Modeling with Real Numbers
by Daniel Payne on 02-15-2014 at 7:00 pm

My first introduction to modeling an AMS behavior using a language was back in the 1980’s at Silicon Compilers using the Lsim simulator. Around the same time the VHDL and Verilog languages emerged to handle the modeling of both digital and some analog behaviors. The big reason to model analog behavior with a language is for… Read More


Stop TDDB from getting through peanut butter

by Don Dingee on 01-24-2014 at 6:00 pm

There are a few dozen causes of semiconductor failure. Most can be lumped into one of three categories: material defects, process or workmanship issues, or environmental or operational overstress. Even when all those causes are carefully mitigated, one factor is limiting reliability more as geometries shrink – and it… Read More
