The user_id_programming block is programmatically changed by moving vias to connect an either high or low met1 to the output met2. The parent routing is expected to connect to met2, however, the lef file has ports on met1 also.
The parent mask_rev[6] is connected a met1 port (low) instead of the programmable met2 layer. Programming this bit to high will have no effect because the met2 is not connected.
