Abstract:
A computer software program embodied on a computer readable medium, wherein the computer software program comprises a plurality of instructions configured to detect floating nodes in an integrated circuit, when executed, the computer software program performing steps comprising of:selecting a plurality of potentially floating nodes from a data file representing the integrated circuit;simulating a first set of one or more resistors coupling each of the plurality of potentially floating nodes to a high voltage;simulating a second set of one or more resistors coupling each of the plurality of potentially floating nodes to a low voltage, wherein the combination of the first and second sets of resistors are configured to cause floating nodes within the plurality of potentially floating nodes to reach a predetermined intermediate voltage level between the low voltage level and the high voltage level without materially influencing the voltage levels of non-floating nodes within the plurality of potentially floating nodes;causing the circuit to enter a simulated test state; andmeasuring the simulated static current flowing through the circuit.
