As mentioned on Slack, this is pending https://github.com/efabless/openlane2/issues/405, as we currently patch this functionality into OpenROAD.

We apologize for the inconvenience.

[hpretl]

Is there a way via config variable to disable the failing step until this is merged into OR?

[donn]

@hpretl --skip Odb.CheckDesignAntennaProperties --skip Odb.CheckMacroAntennaProperties

You could just sed the steps out in openlane/flows/classic.py or pull our OpenROAD patch, both are viable

Fixed in dev
