Hi, I'm
I'm an absolute newbie in PrimeTime (PT) and would like to seek for help in the problem that i have here which depicted in the attached picture.
notes:
1) net a & a_b and b & b_b are complemented pair. Example: a=1, a_b=0 and etc.
2) Control Block A and Control Block B have no dependency on each other. Any combination of net a and b are possible. Example: both passgate1 and passgate2 in cell1/cell2 can be turn ON during the same time.
I would like to get the worst delay number from point (input) to (cell1/pg_1). However with the following PT command, my PT will always switch ON ALL the passgates (passgate1 & passgate2 in both Cell1 and Cell2) so that net input_b will encounter with the with the worst load.
My Question is how can I "force" the content on net cell1/a=0, cell1/b=1, cell2/a=1, cell2/b=1 so that only cell1/passgate1 is ON?
