Virtuoso Liberate 


Standard Cell and Complex I/O Characterization

Virtuoso Liberate provides an ultra-fast cell library characterization solution for standard cells and complex I/Os supporting advanced timing, power and signal integrity DC current source models (CCS and ECSM).

Virtuoso Liberate Datasheet »

Virtuoso Liberate is an ultra-fast standard cell and I/O library characterization solution. As part of Cadence’s complete custom solution for foundation IP characterization, it generates electrical cell views for timing, power and signal integrity including advanced current source models (CCS and ECSM). Virtuoso Liberate meets the rapidly changing needs to create additional library views required for nanometer process technologies to achieve high quality silicon and avoid silicon re-spins due to inaccurate signoff analysis.

Features/Benefits
  • Patented “inside view” approach automatically pre-characterizes each cell using transistor level circuit analysis to learn all internal logic states
  • Enables automatic vector generation (AVG).
  • Ensures a complete, accurate and highly efficient characterization of library cells.
  • Supports complex cells including those required for high speed and/or low power design such as pulse latches, multi-bit flip-flop arrays, level shifters, power switches and cells with sleep modes.
