OPC Model Accuracy and Predictability – Evolution of Lithography Process Models, Part III

OPC Model Accuracy and Predictability – Evolution of Lithography Process Models, Part III
by Beth Martin on 08-15-2011 at 7:00 am

Wyatt Earp probably wasn’t thinking of OPC when he said, “Fast is fine, but accuracy is everything,” but I’ll adopt that motto for this discussion of full-chip OPC and post-OPC verification models.

Accuracy
is the difference between the calibrated model prediction and the calibration wafer result. Accuracy depends on several… Read More


Best EDA company for work life balance?

Best EDA company for work life balance?
by Daniel Payne on 08-10-2011 at 1:25 pm

What was the first EDA company name that came to your mind after reading that title?

At Forbes magazine they rated both Mentor Graphics and Synopsys in the top 25 best companies for work life balance.

That’s quite an honor for both Mentor and Synopsys so I can say that EDA dominated the list this year.

Here are some of the factors… Read More

August 11th – Hands-on Workshop with Calibre: DRC, LVS, DFM, xRC, ERC
by Daniel Payne on 08-06-2011 at 9:29 pm

I’ve blogged about the Calibre family of IC design tools before:

Smart Fill replaced Dummy Fill Approach in a DFM Flow

Smart Fill Replaces Dummy Fill Approach in a DFM Flow

Smart Fill Replaces Dummy Fill Approach in a DFM Flow
by Daniel Payne on 07-30-2011 at 7:11 pm

I met with Jeff Wilson, Product Marketing Manager at Mentor in the Calibre product group to learn more about Smart Fill versus Dummy Fill for DFM flows. Jeff works in the Wilsonville, Oregon office and we first meet at Silicon Compilers back in the 1990’s.

Dummy Fill

Want to learn Mixed-Signal Design and Verification?
by Daniel Payne on 07-20-2011 at 6:13 pm

Workshops are a great where to learn hands-on about IC design technology. Mentor has a free workshop to introduce you to creating, simulating and verifying mixed-signal (Analog and Digital) designs.

ARM and Mentor Team Up on Test

ARM and Mentor Team Up on Test
by Daniel Payne on 06-27-2011 at 2:31 pm

Introduction
Before DAC I met with Stephen Pateras, Ph.D. at Mentor Graphics, he is the Product Marketing Director in the Silicon Test Solutions group. Stephen has been at Mentor for two years and was part of the LogicVision acquisition. He was in early at LogicVision and went through their IPO, before that he was at IBM in the mainframe… Read More


Can Your Router Handle 28 nm?

Can Your Router Handle 28 nm?
by Beth Martin on 06-20-2011 at 7:11 pm

attachment

With the adoption of the 32/28 nm process node, some significant new challenges in digital routing arise—including complex design rule checking (DRC) and design for manufacturing (DFM) rules, increasing rule counts, very large (1 billion transistor) designs. To meet quality, time-to-market, and cost targets, design teams… Read More


Circuit Simulation and IC Layout update from Mentor at DAC

Circuit Simulation and IC Layout update from Mentor at DAC
by Daniel Payne on 06-17-2011 at 7:06 pm

Intro
On Monday evening I talked with Linda Fosler, Director of marketing for the DSM Division at Mentor about what’s new at DAC this year in circuit simulation and IC layout tools.

Notes
IC Station – old name for IC layout tools

Eldo – Eldo Classic- Cell characterization
– ST is the early customer and teaching customer,… Read More


Nimbic (formerly Physware) – 3D Field Solver in the Cloud or Desktop

Nimbic (formerly Physware) – 3D Field Solver in the Cloud or Desktop
by Daniel Payne on 06-13-2011 at 12:57 pm

I met with Bala Vishwanath, CMO at Nimbic on Monday morning. They had just announced a $6.9M round of venture capital which is something that you rarely hear about in EDA these days, especially during a slow economic recovery.

Intro

Physware – served the package and board markets, co-design challenges (can add IC noise sources).… Read More


Shakeup at Mentor Graphics

Shakeup at Mentor Graphics
by Daniel Payne on 05-12-2011 at 12:22 pm

Reading the title you guessed it right, Mentor Graphics has three new board members today from the slate offered by billionaire activist Carl Icahn:

  • José Maria Alapont, chief executive of the auto parts maker Federal-Mogul
  • Gary Meyers, a director of the chip maker Exar
  • David Schechter, an executive at Mr. Icahn’s investment firm
