  • Method and system for performing voltage-based fast electrical analysis and simulation of an electronic design
    Patent number: 8595677
    Abstract: A system, method, and computer program product is disclosed for performing electrical analysis of a circuit design. A voltage-based approach is described for performing two-stage transient EM-IR drop analysis of an electronic design. A two-stage approach is performed in some embodiments, in which the first stage operates by calculating the voltage at certain interface nodes. In the second stage, simulation is performed to simulate the circuit to concurrently obtain the current at the interface nodes.
