If you are interested in finding this information only for LVS discrepancies, then try the LVS Report Option statement. Options A through D might get you what you want.
If you are looking for a more general solution for any net, Calibre PERC is probably the best way to do this. There are dedicated commands for reporting the sorts of things you are after. In the user manual, there is an Example: Reporting Objects With Iterator Functions section that may help you get started. There is no command that gives the format you show below, so you would have to write a userware script to get that.
About the only other way to get this sort of information is through the Query Server NET PINS and DEVICE INFO commands. You'll need the Mask SVDB Directory PINLOC option to get the pin coordinate. The challenge here is, you might end up generating and parsing many response files from the Query Server to derive all the information you want. Again, you'll need a userware script to put things into the format you describe.
The "LVS Report Option statement. Options A through D" works .
Now I can all the instances names that are connected to a particular net.
Thank you very much for your reply .
