CLKDA’s AOCV FX Makes DeepChip’s Top 5 Tools shown at DAC ‘13

Littleton, MA, October 31, 2013 - CLK Design Automation today announced that AOCV FX™ timing derate generator was voted one of top 5 hot tools shown at the Design Automation Conference (DAC) in DeepChip’s annual user survey.  DAC is the electronic design automation (EDA) industry’s premier conference, and users reviewed the products exhibited there.

Advanced Timing Derates are an Essential at 20nm and Below

Advanced timing derates are an essential part of IC design at 20nm and below. AOCV and POCV both work to reduce pessimism and improve margin without impacting quality during static timing analysis and optimization. These tables are a much better representation of on die variation compared with traditional global OCV. They can properly reflect manufacturing variance for a cell based on its depth of in a specific path.  As importantly, advanced timing derates work with existing libraries, physical design tools and STA.  

One designer contributing to the report stated, “[CLKDA’s] primary advantage in this space is the rapid turn-around time for generating the table coefficients using their proprietary modeling capabilities. PrimeTime needs this.” is an online forum with approximately 36,000 subscribers, where semiconductor chip designers contribute data-intensive papers and articles of first-hand evaluations and production benchmarks of commercial EDA tools. The DeepChip DAC Report is an annual survey that started in the 1990′s, where hundreds of users review the products exhibited at the electronic design automation (EDA) industry's premier conference.

“I give a big congrats to CLKDA’s products ranking in the top 5 with chip designers at DAC,” said John Cooley, DeepChip’s moderator. “AOCV helps customers in trouble. Getting to sign-off keeps getting harder, and designers specifically commented on how fast CLKDA generated instance-specific derates.”

“We have been dedicated to making FX technology an enabling element to designers achieving sign-off,” said Isadore Katz, President and CEO of CLKDA. “We are very gratified by the user recognition that AOCV FX can accelerate their design process.”

About AOCV FX™

AOCV FX™ is the leading commercial solution for generating timing derates for use with static timing analysis and physical IC design. AOCV FX™ has made derate table characterization practical and effective. AOCV FX™ can generate a SPICE accurate table for 1000 cells in a few hours per corner, where other solutions require weeks to generate tables for a few simple cells.  

These advances in derate table generation are made possible by CLKDA’s FX Platform. The FX Platform is a trusted model, circuit simulator and variance solver that sits at the heart of CLKDA’s margin analysis applications.  FX has been validated at all of the major foundries, and is in production at the most advanced process nodes in use today.  The FX Variance Platform provides 3σ statistical accuracy 300,000 to 500,000 times faster than Monte Carlo SPICE.
