When is the

user_id_programming

value set? Is it when the designer issues the tape out command or does efabless do that later?

As far as I can see the user_id cell is created during the tapeout procedure, at there there is a respective cell for that.

Thanks @User, I saw a target in

caravel/Makefile

, but I wasn't sure if that was the one actually used.

I see there is set_user_id.log getting generated during tapeout run

Thanks, @User. There appears to be a gds created with the correct vias, but that gds is not included in the final gds.
