I encounter a LVS issue. My top source netlist has 34 ports , but after merging nets or filtering instances in source , it show the following Error
Error: Power Shorted to ground while merging nets or filtering instances in source
I alse attach a snapshot showing the LVS error .
Why is there short in the source , I can never encounter it.
How to debug it ?
Netlist shorts can occur for various transformations; for example, if the rules include LVS FILTER ... SHORT, pins left over after device filtering are shorted together. That isn't great for diodes. Perhaps LVS WRITE SOURCE NETLIST will help? It will at least let you see the netlist after transformations.
