I tried to make my layout using the rf_nfet cells offered by the sky130A library. The smaller cells work just fine, but something very weird happens when I tried to use the larger e.g. (sky130_fd_pr__rf_nfet_01v8_bM04W1p65L0p15.mag) cells: When I place the subcell in an empty top cell, the DRC is all green. But once I placed anything in that layout, a metal 1 for example, a lot of DRC errors begin to pop up. I think it has something to do with that "magscale 1 2" hack sky130 is using. Has anyone encountered the same issue before?
