FileNotFoundError: [Errno 2] No such file or directory: 'sta'

daquintero commented 5 months ago

Hello!

I have tried running openlane --smoke-test on openlane 2.08, 2.07 and 2.06 all within the nix-eda environment. Does the nix environment just involve the downgrade suggested or a future patch?

I installed nix following these instructions tested in the latest ubuntu 22.04 native. The command I run for nix-eda is nix shell .#{ngspice,xschem,verilator,yosys}

Full error is:

Hi Dario, sorry just saw this-- that's a different error.

nix shell .#{ngspice,xschem,verilator,yosys} would not install OpenSTA, so OpenLane would not run. You need to get OpenLane with its dependencies in the same shell:

nix shell github:efabless/nix-eda#{ngspice,xschem,verilator,yosys} github:efabless/openlane2

Then invoke it using simply openlane (not python3 -m openlane).

Hi Donn, thanks so much for the help! This is a really modular way of implementing the nix environments, and quite extensible. Sorry today had intended to try it out and now it's working great because of this! Look forward to meeting in Paris for FSIC

efabless / nix-eda
