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.
