Hellow everyone. 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?
v
It's mean, are you using OpenLane flow?
y
Yes.
v
SIGNOFF_SDC_FILE can be used Otherwise you have to update scripts or use interactive mode to read different SDC file
y
SIGNOFF_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?
v
You can customise flow as per need, to read different files
y
Does it mean that I need to modify openlane's script, not config.tcl?
v
Yes

Thank you for your reply. I got it.
