Hello, I got LVS error when harden the top wrapper in GF180. Any suggestion?

Looks like the top level has been synthesized, resulting in adding a tie cell that’s not connected to power/ground. Try opening the gds to see if you can find a lone

conb

cell at the top level. You probably want to tie off your inputs in

user_proj_example

so that all you have at

user_project_wrapper

is routing.

Yes, I should not tie all wb_* and la_* at

user_project_wrapper
