Missing leading '*' in line 16 of sky130_fd_pr\latest\cells\nfet_05v0_nvt\sky130_fd_pr__nfet_05v0_nvt.pm3.spice

[holvo]

Expected Behavior

Line 16 should read * include "sky130_fd_pr__esd_nfet_05v0_nvt.pm3"

Actual Behavior

Line 16 now is: include "sky130_fd_pr__esd_nfet_05v0_nvt.pm3"

Because of leading 'i', ngspice tries to add a current source.

Steps to Reproduce the Problem

1. 1. 1.

Specifications

• Version: v0.20.1
• Platform: Windows 10

[dwarning]

This problem still exist! Please comment line 16 in cells/nfet_05v0_nvt/sky130_fd_pr__nfet_05v0_nvt.pm3.spice. The pm3 file is not available. Whatever meaning it has.

@dwarning : You should not be using the Google version of the respository, which is not being updated or maintained. You should be using the Efabless fork of the repository, which has corrected this and several hundred other errors. The open_pdks installer uses the Efabless fork of sky130_fd_pr, so those corrections are in all installed PDKs derived from open_pdks, including the pre-compiled volare PDKs.

Thanks Tim, I want only simulate. Is there a way to disable all the tool dependencies like magic etc. in configure step of open_pdks? I tried ngspice simulation with the pure efabless clone but with that the relative pathes are wrong by using skywater-pdk-libs-sky130_fd_pr/combined_models/sky130.lib.spice :

@dwarning : I think this is my omission; the "all.spice" file should be pointing to directories in the repository, not the installation, for the express purpose of doing exactly what you are attempting to do, which is to run simulation out of the repository without an installation. I will correct it.

[RTimothyEdwards]

@dwarning: Please pull the latest commit and try again. Let me know if the issue has not been resolved.

[dwarning]

@RTimothyEdwards: Thanks, it is much better now - I can simulate with git clone from efabless only.

[RTimothyEdwards]

@dwarning : Thanks for the thorough testing and finding those last (I hope) errors. I just fixed both in the repository.

[dwarning]

Now it is clean - not any missing notice. Thank you! My noise evaluations with nfet_01v8 and pfet_01v8 show reasonable results.

[RTimothyEdwards]

@dwarning: Good confirmation, and thanks again!
