How should I use skill code to get the mapping between instanceName and its terminalName and netName

Hello,

This seems like a simple problem to address but the answer is not as simple as it looks!

I rewrote a code snippet from older scripts I had, if someone have a simpler solution please share it!

Code is below, it is written in SKILL++ and defines only get_inst_term_net function to be used like :
(get_inst_term_net (geGetEditCellView) "I15<0>" "is_500nA<4>")

Hope this helps, don't hesitate to give feedback in case you face any issue or notice a bug
