  • Method for modeling bidirectional or multiplicatively driven signal paths in a system to achieve a general purpose statically scheduled simulator
    Patent number: 5455928
    Abstract: A method is disclosed whereby systems having bidirectional and/or multiplicatively driven data paths are statically scheduled for simulation. The method flattens the netlist to convert bidirectional data flow paths into unidirectional, multiplicatively driven data paths. All drivers connected to multiplicatively driven data paths (or nets) are isolated from the net using a bus resolution block. The bus resolution block implements a resolution function which permits the system to be statically scheduled for simulation. Simulation speed is increased substantially thereby.
