1. A device, comprising:
a frontside power network having frontside supply rails that supply core voltage in multiple different domains including multiple core voltage domains that are separate and distinct from ground voltage;
a backside power network having backside supply rails; and
frontside-to-backside intermixing architecture having transition vias that couple the frontside supply rails of the frontside power network to the backside supply rails of the backside power network,
wherein the transition vias are used to provide a direct power tap between the backside supply rails to the frontside supply rails.
