Patent ID: 7984407

Claim:
A method for reducing standby power for a programmable device, the method comprising: identifying configuration memory cells responsive to instantiation of a user design in a test platform of the programmable device; via programming the programmable device during manufacturing thereof to: not form a first set of contact vias associated with a first portion of the configuration memory cells that are not used by the instantiated user design; and form a second set of contact vias associated with a second portion of the configuration memory cells that are used by the instantiated user design; and forming one of a first contact via or a second contact via for coupling a circuit of the programmable device to either a first supply voltage or a second supply voltage; wherein the first supply voltage is greater than the second supply voltage, the first contact via is formed for the circuit being in a speed-limiting path, and the second contact via is formed for the circuit not being in a speed-limiting path.
