Claim:
1. A method of setting a supply voltage in a device, the method comprising: receiving a first plurality of inputs from a plurality of sensors that are representative of a gate delay of a signal path on the device; receiving a second plurality of inputs from a plurality of temperature sensors; estimating a plurality of interconnect delays for the signal path based on the second plurality of inputs; and determining a value of the supply voltage for the signal path based on the first plurality of inputs and the plurality of interconnect delays; the method further comprising: determining a representative temperature from the temperature sensor inputs; and retrieving a collection of parameter values from a memory based on the representative temperature, wherein the supply voltage is further based on the collection of parameter values, further wherein estimating an interconnect delay in the plurality of interconnect delays comprises: determining a resistance value based on the second plurality of inputs; and determining the interconnect delay based on the resistance value.
