Kronos Characterizer

High performance, high-throughput cell library characteriser for standard cells, multi-bit cells, and I/O cells.

High-performance library characterisation tool that generates accurate Liberty and Verilog/VHDL models for a wide variety of cells including: standard, multi-bit, and I/Os. The tool supports complex stimulus creation and measurement methods, as well as versatile control of output model syntax.


  • High throughput with fast runtime & multi-simulation job control
  • Native integration with AFS & Eldo for high performance
  • Highly scalable architecture, parallelizable up to 1000’s of CPUs
  • Dynamic resource scheduling for on-the-fly modification of CPU resource pool size
  • Disk I/O optimized for improved data storage utilization


  • Fast & accurate LVF for timing, power, & constraints with full SPICE accuracy
  • Supports LVF Moments for nonGaussian distributions
  • Re-characterization flow adds new functions to existing libraries or creates new libraries
  • Accounts for changes in process models, cell layouts, & SPICE models
