Design Structure for an On-Demand Power Supply Current Modification System for an Integrated Circuit

A design structure embodied in a machine readable medium for a circuit for selectively connecting one or more external paths with an integrated circuit, the one or more external paths including a first signal path, the design structure of the circuit comprising:

• a second signal path internal to the integrated circuit;
• a power network internal to the integrated circuit;
• a first means for switching amongst a plurality of inputs including said second signal path and said power network;
• a second means in electrical communication with said first means, said second means for switching amongst a plurality of external paths including the first signal path and the power supply, wherein when said first means is connected to said second signal path, said second means is connected to the first signal path such that said second signal path and the first signal path are in electrical communication, and when said first means is connected to said power network, said second means is connected to the external power supply such that said power network and the power supply are in electrical communication.
