XE-DMRC

XE-DMRC (Design Methodology Rule Checker) allows you to create perl scripts to access XE-Core data and check your electrical design rules.
        • A Perl script uses XE-DMRC APIs to obtain XE-Core circuit analysis properties, perform design checks, and report results.
        • An optional spf file is processed to add layout RC data of each net and parasitic data of each transistor into XE-Core circuit analysis properties.
        • User-directive file is processed to override the XE-Core circuit analysis properties.

The following electrical design rules had been coded and deployed:

  • Edge rates/fan out check
  • Output capacitance and driver strength check
  • Dangling nodes check
  • Beta ratios check
  • Stack height check
  • Serial pass devices check
  • Cross-coupled structures check
  • Dynamic-gate feedback structures check
  • Latch feedback structures check
  • Sense-amp transistor sizes check
  • Ram-cell transistor sizes check
  • Dynamic-gate usages check, dynamic Stage Check, general domino topology
  • High/low Vth transistor usages check, supply check
  • Clock skew check
  • XY distance check
  • Back to back latch check
  • Device Hi_Vt usage check
  • Max RC check
  • Connection directly to main Vdd or Vss supply check
  • Device size check
  • Writability and feedback checks
  • EM check
