#210 Extraction creates spurious pin on some sky130_fd_sc_hd__a21bo_1 cells New issue created by antonblanchard I have a design that is failing LVS because

sky130_fd_sc_hd__a21bo_1

cells have gained a pin (

w_69_21#

):

.subckt sky130_fd_sc_hd__a21bo_1 A1 A2 B1_N VGND VPWR X VNB VPB w_69_21#

I'm a bit lost as to how to debug this. I know the issue is in the top and bottom left of the cell. I also know the labels are being created in Magic in

extHardGenerateLabel()

. Enabling the debugging in there shows every bad label:

Hard way: generated label = "_34823_/w_69_21#"

I'm not sure why we are creating them however. There's a

VNB

or

VPB

pin nearby. RTimothyEdwards/open_pdks
