Abstract: A method for evaluating a power distribution network for a circuit has steps of creating a circuit model of the circuit in which all wires and transistors are represented as circuit elements, with the model comprising a plurality of nodes. A DC power analysis is performed on the circuit model to determine voltage drops at a plurality of the nodes.

Abstract: A system embodiment for controlling an electrical signal level has a first and a second switch, with one of the switches connected to a high voltage source and the other connected to a low voltage source. One of the switches is biased to an on position when the voltage is less than the low level, with the signal increasing to a level of at least the low level while the switch is biased to the on position. The other of the switches is biased to an on position when the signal is greater than the high level, with the signal discharging to at least below the high level while the switch is in the on position.
