Extend power.tcl to check the power reporting procedure for acceptable numbers
Description
Start simple, define some smoke-test level criterea for "it worked" and create a PR to update https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts/blob/master/flow/designs/asap7/mock-array/power.tcl with that check(print error and exit 1).
Perahaps require some factor of difference for the relevant cases below. Is there an OpenSTA .tcl interface that can be used? Didn't find anything in the manual...
Later on as usage and understanding becomes more sophisticated, the regression tests can be refined.
To run:
make DESIGN_CONFIG=designs/asap7/mock-array/config.mk final simulate power
At the end make power outputs something like:
Found 1288 unannotated drivers.
Found 7560 partially unannotated drivers.

@tspyrou / @maliberty
Do you want me to look into this issue for my first contribution to open Road project?
@socclosure I don't think this is a good candidate as the problem is in sta itself. We do label good first issues. Perhaps https://github.com/The-OpenROAD-Project/OpenROAD/issues/4041 ?
@maliberty Make sense. Thanks for information. I will look into Good first issues to start the contribution.
Try sta::design_power [sta::cmd_corner]. You can replace sta::cmd_corner with sta::find_corner <corner> for a particular corner
