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. Web3 Measure the setup and hold times (10pts) As a second step, use Cadence to measure the setup and hold times of your flip-flop. Recall that the setup and hold time are the minimum time before and after the rising clock edge the input signal must remain constant to store the signal and to generate a stable output, respectively.

WebDec 8, 2024 · It will help solve any hold violations. 3. Increase the clock-q delay of launch flip-flop. Similar to the previous fix, by choosing a flop that has more clock-q delay, delay can be induced in data path logic. It will ease timing and help solve hold time violations. 4. Use a slower cell for launch flip-flop.
