@jerryz123 any action I need to take to resolve this failure? https://github.com/ucb-bar/chipyard/actions/runs/4301027445/jobs/7511505150

Not sure if that's just a spurious problem, and the job needs to be restarted.

Huh, well now that same job has failed twice: https://github.com/ucb-bar/chipyard/actions/runs/4308888281/jobs/7515872594

Any clues as to why? Does the CI job need to by run by mergify or something?

Actually, #1367 added your changes in with another fix. Let's merge that PR in to get your changes.

Sounds good!

As for the CI issue, if PR'ing from a fork you don't have permissions to run CI. So you have to run mergify rebase/copy to create a new PR that is local to the repo to get permissions and run the CI (only devs on the repo can use mergify)

Makes sense, thanks!
