CSR Deploys Altos’s Liberate™ LV for Library Validation

San Jose, California – July 15, 2009 – Altos Design Automation today announced that CSR (LSE: CSR) has adopted the Altos Liberate LV solution for library qualification and validation. Liberate LV has enabled CSR to ensure timing validation of their 90nm standard cell library by correlating static timing analysis (STA) results to transistor level SPICE simulations.

Graham Pink, SVP Engineering at CSR, said "Using Liberate LV, we were able to identify an inconsistency between foundry process models and the library views provided by one of our IP suppliers. Pink continued, "By validating the library, we are able to understand our timing margins and ensure silicon correlation. We are impressed at how easily Liberate LV is to use and that we were able to validate a complete 90nm library in a single day".

“Our relationship with CSR further emphasizes the need for semiconductor design automation organizations to use library validation technology to deliver high quality libraries to product development groups.” said Jim McCanny, Altos CEO and founder. “Using Liberate LV, CSR will be able to rapidly qualify library views for electrical signoff of timing, noise and power.”

About Liberate LV

Liberate LV is an independent and comprehensive solution to validating and qualifying library views. This includes checking all functional, timing, noise, and power data for potential problems before wide-spread use by multiple design teams.

Liberate LV performs a number of necessary library validation steps including ensuring functional consistency between the transistor level sub-circuits and the Liberty® , Verilog and Vital files; accuracy validation of electrical analysis tools analysis versus SPICE circuit simulation and library version comparison. It is able to correlate both current source modeling delays and NLDM delays against actual spice simulation results. These results are available in graphic form, ASCII results or readable in spreadsheet applications. Liberate LV supports a variety of commercially available circuit and logic simulators and numerous sign-off analysis tools.
