Hi, is it generally possible to use multiple power domains in a design with the openLane tool flow? (E.g. to power gate a processor core) In the openRoad Docs following is mentioned: "A P&R block is limited to one logic power domain and one I/O power domain. Additional power domains must be handled manually (OpenROAD Tcl scripting)." I have not found any example using more than one core power domain nor do I find any other information regarding this and the "(OpenROAD Tcl scripting)".
