| Before I file a bug, I want to make sure this is unexpected behavior.
|
|
|
| In my sdc file I do a
|
| ```
|
|
|
| set_max_transition [exp $clk_period * 0.20] [current_design]
|
| set_max_capacitance 30 [current_design]
|
| ```
|
|
|
| and then read a floorplan by setting FLOORPLAN_DEF.
|
|
|
| When I run through floorplanning, 2_floorplan.sdc doesn't have those commands. I've narrowed it down to floorplan.tcl's `read_def -floorplan_initialize` that's removing these. Max transition and max capacitance can't be set in DEF if I remember correctly, so this is unexpected. Is this the desired tool behavior?

| I would consider it unexpected so go ahead and open an issue with a test case |
|
|
| ### b62833 |
| Over the weekend I upgraded to OpenROAD version 2.0-13286-gebcc5196e and it works now.
|
|
|
| It was broken in the version v2.0-11493-gaddecc2bd that I'd been using before.
|
|
|
| We're good now. |
