Input through .VEC file

Dear PrateekSharma,

I mean for the first 20 inputs I need a time period of  8ns, and for the remaining 20 inputs I need a time period of 0.125ns.
Can we use period 8 and after 20 inputs again mention period 0.125?

As an alternative, perhaps the following awk script (executable from a UNIX prompt) might satisfy your needs. Basically, you set the period in your vector file to the minimum period - in your case 125 ps. Then, using your tabular vector inputs (one period per vector where the period is 8000 ps for the first 20 vectors and 125 ps for all vectors beyond that, run the folliowing awk script. It will expand your vectors to repeat the first 20 vector lines by (8000 ps/125 ps) and leave th remaining vectors unchanged. This effectively sets the period of the first 20 vectors to 8000 ps and the remaining to 125 ps. The script has arguments corresponding the to the maximum period (per_max) and minimum period (per_min) and the vector number beyond which the period is changed from per_max to per_min (vector N). I've attached an example with the script shown at the end of the example. In the example, the sample vector file has 24 lines. Hence the expanded vector file should have 20*(8000 ps/125 ps) + 4 lines. I've shown that this is the case. The example input vector file is also attached.

Simpler still, just use two vector files - one for each set of signals (one for the first 20 inputs with the period of 8ns, and a second for the second 20 inputs with a period of 0.125ns). You can only have a single period in each file, but in this case splitting it into two files doesn't seem particularly onerous to me?
