I want to use 2 sdc for 2 defferent mode.
config.tcl in OpenRoad has "BASE_SDC_FILE" line for sdc.
Can I set 2 or more sdc files here?
(I tried it, but it didn't work.)
If yes, how should I write?

Otherwise you have to update scripts or use interactive mode to read different SDC file

04/26/2024, 2:56 AMSIGNOFF_SDC_FILE is used for signoff phase, isn't it?
I want to use several sdc files for all flow(BASE_SDC_FILE, PNR_SDC_FILE. RCX_SDC_FILE).
Is it possible?

04/26/2024, 2:59 AMDoes it mean that I need to modify openlane's script, not config.tcl?
