on opencircuitdesign.com fixes this issue.

@Tim Edwards that made a big difference in getting LVS to pass but there were still a couple of other things I needed to do to make it work: 1. In the library spice files the

sky130_fd_sc_hd__diode_2

diode uses the parameters

a

and

p

which don't match the extracted

area

and

perimeter

parameters 2. The

sky130_fd_sc_hd__conb_1

library cell uses subcircuit (X prefix)

sky130_fd_pr__res_generic_po

devices while the extracted devices are resistors (R prefix) I've modified my

sky130_fd_sc_hd.spice

file to match the extracted versions. Is this the best approach to take? If so I can raise an issue and/or pull request detailing it

Thanks; I should have noticed the

R

instead of

X

. The area and perimeter difference I have to look into to make sure that the change is the intended one. I just coded it up in python as a regexp string substitution, so fixing the installation to match your changes should be easy enough (plus, it applies them to all the digital standard cell libraries, since I found that the problems occur in all of them).
