IDSIM2: an environment for mixed-mode simulation

IDSIM2, an integrated computer-aided VLSI design verification environment in which several types of simulation tools share a common hierarchical circuit database is described. IDSIM2 performs a mixed fast-timing/circuit simulation and supports a parallel processing feature. Several feedback processing methods are also available. Results demonstrate a speedup of up to 1000 times over conventional circuit simulators on typical mostly digital circuits. IDSIM2 accepts a SPICE input circuit description and flattens it to create a circuit database. Processing steps are then applied to add information to the database.<
