What to do about the timing ECO flow? #1424

Closed donn closed 1 year ago

donn commented 1 year ago

The current timing ECO flow is:

A. Untested in CI, Broken B. sky130_fd_sc_hd-specific https://github.com/The-OpenROAD-Project/OpenLane/blob/32da932761213af689f10088d671e1e3dc38f273/scripts/odbpy/eco.py#L87 C. Uses a clone of report.py, scripts/report/report_routing.py, which has gone out of sync for a couple of months now.

It appears UMich is no longer interested in maintaining the ECO flow, so I wonder what we should do about it. I'm leaning towards disabling it at the moment until the Core OL team has more time to rewrite it.
