[SI-LIST] Re: HSPICE stimulus question

---------- update from W. Beal -------------
Some of you have been using my utility to create SPICE PWL voltage sources 
and have provide useful comments.  I've fixed a few things and made it bit 
easier to use.  You can get the new version at
http://groups.yahoo.com/group/si-list
in the files folder called utilities get the the file, ptgen.zip.

Regards,
Weston

This topic has been covered on the list not too long ago.

See a message from Wis Macomson on 22 Nov 2002
(http://www.freelists.org/archives/si-list/11-2002/msg00263.html )
where he provide PERL code to accomplish the task of generating
PRBS values in a PWL statement.

Here is the output using the code's default values:

* PRBS(127), seed=0, 32 bits
* 1 0 0 0 0 0 1 1 0 0 0 0 1 0 1 0 0 0 1 1 1 1 0 0 1 0 0 0 1 0 1 1
* bit time=1.5e-09 sec, rise/fall=1.5e-10 sec
