  • Method and apparatus for implementing multiple configurations of multiple IO subsystems in a single simulation model
    Patent number: 7103523
    Abstract: A method and apparatus are provided for implementing multiple configurations of multiple input/output (IO) subsystems in a single simulation model. At least one bus routing switch is included in the single simulation model. Each bus routing switch includes a plurality of ports respectively connected to a plurality of IO busses. Predefined ones of the plurality of IO busses are connected to respective multiple input/output (IO) subsystems in the single simulation model. The bus routing switch is selectively configurable for interconnecting predetermined ones of the plurality of ports. The bus routing switch includes a variable delay latch structure to simulate the effect of long wires. Each bus routing switch includes a plurality of multiplexers. Each of the plurality of multiplexers includes inputs connected to the plurality of ports, an output connected to a respective one of the plurality of ports and has a control input for configuring the bus routing switch.
