Can you check your pdk version?

you should checkout to the tag mpw7g, make setup to reinstall the env

@Mitch Bailey I have the following in my Make file ifeq ($(PDK),sky130A) SKYWATER_COMMIT=f70d8ca46961ff92719d8870a18a076370b85f6c export OPEN_PDKS_COMMIT?=0059588eebfc704681dc2368bd1d33d96281d10f export OPENLANE_TAG?=2022.11.19 MPW_TAG ?= mpw-8a

https://open-source-silicon.slack.com/archives/C02K4RD241Y/p1668950760732129 I have met the same problem, I just create a new repo and checkout to the tag

I see the file in volare

3af133706e554a740cfe60f21e773d9eaa41838c

$PDK_ROOT/volare/sky130/versions/3af133706e554a740cfe60f21e773d9eaa41838c/sky130B/libs.ref/sky130_fd_sc_hd/lef/sky130_ef_sc_hd.lef

Inspite fo this error, the next two steps of timing checks

make create-spef-mapping
make caravel-sta

completed without any errors. Precheck is also successful and tapeout happened. So ignoring this error as of now.
