Features

  • Setup/hold time diagnosis for function/noise violations
  • Repairing library model from function/noise violations
  • Inaccuracy diagnosis by library model comparison
  • Function verification between views of library model
  • CCS consistency check of library model
  • Interactive Debugger by GUI

    Necessities

  • Use ultimate validation, different from characterization -Verify setup/hold time by direct data plugging into final
       simulation, instead of binary search with error tolerances
  • Check internal nodes, not covered by characterization   -Examine glitches and noise strenths on internal nodes,
       instead of ‘output pins only’ by simulator’s bi-section
  • Verify possible errors in the characterization from   -Characterization tools
      -Simulation tools
      -Human errors and manual settings

    Benefits

  • Enable quality assurances of cell library .Lib models
      which are critical for SoC designs
  • Quickly locate the function, noise,timing and power
      problems in .Lib model at any PVT
  • Repair .Lib model of latch/flip-flop by automatically
      adjusting the margins for production yields
  • Easy to use with Interactive Debugger by GUI, and
      programmable configurations
  • Fully proven for production flow
  • Best price performance
