Hello all!, I'm trying to run the basics inverter OpenLane's Colab Notebook but seems to be failing, if I run it as it is I get the error:

[ERROR]: Conflicting values of RUN_CTS and CLOCK_TREE_SYNTH; please remove CLOCK_TREE_SYNTH from your design configurations

If I remove the CLOCK_TREE_SYNTH param from the config.json I get the error:

and no GDS is generated, anyone has faced the same issue? Thanks in advance!

You might try using an older version of openlane. Looks like the colab you shared used

2022.11.12_3

Wiil do, thanks!
