   Thanks! When I run it now I get another error as well.

   This is due to the way inheritance is used in DVSim. The sim_cfg variable is misleading as it implies that only sim configs are used. Where in this case it's a LintCfg.

   We can fix this up fairly easily, but longer term we need to remove the inheritance to avoid unintended side effects like this.

   See my comment here: #133 (comment), as that issue is now essentially a duplicate of the new error James is reporting in this issue.

   I agree that a longer term fix is very necessary to prevent future breakages like this, but the easy fix is available in a PR here: #139

   I can't run the lint locally at the moment to verify it works, but I at least don't get any errors and I'm getting through to the scheduler, so hopefully that should fix this issue as well?
