I wasn't sure to make of Cadence's announced Power Forward Initiative. This is such a nascent field, do we know what to standardize?
But then I could think of some design practices that would be very good to have a standard way to describe and verify, such as what voltage and power domains various parts of the design should be connected to, what is the design convention for isolation and level shifting, etc.
This could be a useful standard. Let's hope it doesn't degrade into another Cadence vs. Synopsys "we have two standards so we have no standard" like ECSM and CCS libraries!
