Solving the EDA tool fragmentation crisis

Design teams are facing challenges with EDA tool fragmentation as specialized tools for IC verification struggle to share design data efficiently. The Calibre Connectivity Interface (CCI) aims to bridge this gap by transforming Layout vs. Schematic (LVS) verification data into a universal source that downstream tools can access accurately. CCI operates on the Standard Verification Database (SVDB) to provide rich connectivity data for various analysis tools, including parasitic extraction, electromagnetic simulation, and power integrity analysis. Integration with third-party tools like Empyrean's PEX, Phlexing's GloryEX, Synopsys StarRC, and Cadence QRC showcases CCI's ability to streamline workflows and enhance design accuracy. The article emphasizes the importance of seamless multi-tool integration in modern IC design to improve efficiency and accelerate time-to-market for semiconductor innovation.
