Web30 nov. 2007 · Period - pilse period. Tstop. second. Define a pulse waveform using the format and ensure that it meets both the setup and hold time and then check if the output follows the input. Then assign the delay value to be a variable. Lets say for example the clock rises at 10ns. Sweep the delay variable from about 5ns to 12ns.
