I'm using power integrity of cadence. But, There isn't VRM data of my board design. where did I get it? May I use default value?
Are you getting an error saying that you don't have the PQ_VRM and PQ_NOISESOURCE models?If so, welcome to the club! The models are stored in :C:\Program_Files\Cadence\SPB_15.7\share\pcb\signal\power_integrity.dmlOf course you need to substitute your own install directory.Go to Analyse - Library - Add Existing library to point PI to this library.
