OpenDFM Physical Verification Standard

The Design for Manufacturability Coalition (DFMC) have approved the first official release of the OpenDFM 1.0 standard. OpenDFM is an open, high-level DRC language that can generate verification languages with no loss of accuracy or performance. OpenDFM utilizes a more compact notation for physical verification than traditional DRC rules. Tests show OpenDFM can reduce the volume of DRC rules by 5x-20x. OpenDFM describes verification intent for leading process nodes, including conditional rules and ranges of acceptable values. It leverages a plug-in architecture to automatically generate output decks.

OpenDFM Overview

  • Open Standard with a reference parser for DFM verification
  • OpenDFM describes the verification intent and not how to verify
  • 3X-20X smaller DRC rule file size than proprietary rule files
  • Defines a meta-language with a higher level syntax than DRC rules
  • DFM verification parameters are passed to vendor plug-ins to be translated into proprietary verification rules
  • Performance of translated OpenDFM rules is almost identical to native DRC
  • Great for designers who want to add high value proprietary checks to the basic ground rules
  • Ideal for EDA Vendors who want to showcase performance/capabilities of their engine
  • Benefits Silicon Foundries who do not want to develop multiple/redundant DRC rule decks
  • DFM verification and analysis can be completely separated from the verification engine that implements that intent
  • Experts can focus on where they add value
  • Available now to the public at no charge
