Title: Input file for vpwlf source
Post by kamesh419 on Feb 18^th, 2005, 6:54am

Dear all,

I came to know that vpwlf source in cadence can take its input from a file and convert it to pwl sources. I need to know how the "input file" should look like for the vpwlf source (I have information like at what time i pass what digital inputs to my 8-bit adder). an example file will be better. Then i can use TCl to generate such a file.

If you can give me the logic behind generating this file then that will be great. :)

Thanks in advance
kamesh.

From "spectre -h vsource":

Quote:

A vector of time-value pairs describes the piecewise linear waveform. As an
alternative, you can read the waveform from a file. In this case, you give time-
value pairs one pair per line with a space or tab between the time and the
value.

Regards,

Andrew.
