while hardening the user_project_wrapper using make user_project_wrapper I got a LVS error! Should I make changes to my user_defines.v file or how should I proceed ?

find . -name '*lvs.lef.log*'

I video i was following asked to make changes in the pin.cfg file of the user_proj_example but. I did that and no mismatch is found there, But it said nothing about the pin.cfg of the wrapper

user_project_wrapper

uses

FP_DEF_TEMPLATE

in place of

pin.cfg

. Can you share your full

*lvs.lef.log

@Paras Dewangan at the

user_proj_example

level, there is a pin discrepancy.

Copy code
