Hi,
I'm trying to measure the path length of any rectangles or paths that are attached to my transistors using SKILL. For this, my approach is to try to get all nets connected to a transistor (or any other PCELL for that matter), identify which port of the transistor they are attached to and measure their length. Is such a thing possible? If so, can anyone please illuminate how it could be done?
I drew up a figure quickly to show you what I mean.
If this was my layout for example, the output of the script should be:
1. NET123: Metal1, S, 2um.
2. NET456: Metal1, D, 2.9um.
Is this possible to do? Can you programmatic figure out which nets are connected to which port of a transistor, and tell which metal they are in? From looking at other posts, it seems possible that you can figure out the length so that is probably not an issue.
Thanks for your help.
