ABSTRACT:
A method of operating a programmable logic device, including the steps of enabling resources of the programmable logic device being used in a circuit design implemented by the programmable logic device, and disabling unused or inactive resources of the programmable logic device that are not being used in the circuit design. The step of disabling can include de-coupling the unused or inactive resources from one or more power supply terminals. Alternatively, the step of disabling can include regulating a supply voltage applied to the unused or inactive resources. The step of disabling can be performed in response to configuration data bits stored by the programmable logic device and/or in response to user controlled signals. The step of disabling can be initiated during design time and/or run time of the programmable logic device.
