Hello everyone,
I want to know if this is correct, in my Core module I had multiple sub-modules, when I fill in the "FP_PDN_MACRO_HOOKS" I usually use the power pin connection" vccd1 vssd1 vccd1 vssd1". Usually that generates some LVS errors because some sub-modules are not connected to those pins, so I go to OpenROAD -GUI and just choose the power grid that passes over the module.
e.g. the "6__7_" module is connected to vccd1, and vssd1. but as u can see in the picture the power pin cannot be connected to the module "7__6_" so I used power pins vdda1 and vssa1.
My questions are: that is a correct connection? that could generate some error? How can I uses only vccd1 and vssd1?
