Hello, When I load the user_project_wrapper.def there are supply grids for vccd1, vccd2, vdda1 and vdda2. But we are only going to use vccd1. Can someone tell me if I can delete (or not load) the routes in metal4 and metal5 corresponding to the supply nets I will not use? I wonder if doing so could produce problems with the precheck.

i dont think is supposed to be used, its just a remaining file that can be used to import IO placement and thats it

you don't need them, but you can't get rid of the power rings as doing so will cause xor failures at precheck
