Application Note for Derating setup/hold Perl Program1. Identify the number of the saved waveformSave the simulated waveforms (include the data/address signal and its associated clock signal) in xxx.sim file. Re-open the file: xxx.sim. Look at the final number at the waveform name; the number represents the waveform in perl program. It should be similar to Figure 1.Figure 1. The sequence that the waveform is saved in SigWave2. Calculate the derating setup/hold timeIn the example shown in Figure 1, we see that number 1 represents theaddress/command and/or control signal waveform; its clock signal waveform is number2. Run the perl program as shown in Figure 2.
