Hello, has anyone seen this error before? Any help would be greatly appreciated.

@Vinay Ivaturi Can you check that the openlane/openroad version and pdk versions are up-to-date.

They seem to be up to date

Great! What’s the pdk and openlane version?

pdk: open_pdks 78b7bc32ddb4b6f14f76883c2e2dc5b5de9d1cbc openlane: OpenLane 30ee1388932eb55a89ad84ee43997bfe3a386421

@Vinay Ivaturi Looks like the pdk is from last year

├── 78b7bc32ddb4b6f14f76883c2e2dc5b5de9d1cbc (2023.07.10)

and I couldn’t find

30ee1388932eb55a89ad84ee43997bfe3a386421

in

<https://github.com/The-OpenROAD-Project/OpenLane>

Does it have an associated tag? Openlane works for me if I use these settings in the Makefile, but I don’t know that this is the official version.

export OPEN_PDKS_COMMIT?=0fe599b2afb6708d281543108caf8310912f54af
        export OPENLANE_TAG?=2023.07.19-2

would this error be related?

@Vinay Ivaturi could be related to the pdk being out-of-date.
