Subject: Library Compiler Won't Take Discharge Cells
Hello John,
I have a problem/challenge - how to "feed" Library Compiler with discharge
cells? As it was proposed in the course -- the general direction is to
define it as an ITS module. I've been searching in the openbook ("Synopsys
On-Line Docs") for an example of discharge cells but I found none.
I would really appriciate if someone could send me an example of ITS format
with the required timing arcs (I mean the names/kinds of arcs -- not the
numbers) for a discharge cell. Here is an example of a typical circuit:

Let's say that the EN input is clock or "something & clock"
