WebNowadays the non-linear delay model (NLDM) or the composite current source timing model (CCS) based look-up table (LUT) is widely used for static timing analysis (STA). In those LUTs, the characterization data such as cell delay and transition time is indexed by a fixed number of input transition time and load capacitance values. WebOct 10, 2024 · Liberty Analyzer handles multiple NLDM, NLPM, CCS and ECSM models at library, cell, pin and individual arc levels while providing insightful statistical data. It displays and plots relative and absolute differences with configurable thresholds for easy spotting of trends and outliers.
