  • Synchronized simulation of software and hardware in the analog domain
    Patent number: 6980945
    Abstract: The present invention provides a method for accurately evaluating the operation of a device by the synchronized analog simulation of software and hardware using numerical integration to model the hardware. The synchronized simulation is conducted by a control program that is embedded in the software processing model and superimposed on the numerical integration program so as to execute the software operating instructions in proper time relation relative to the calculated hardware waveforms. The invention control program determines whether hardware simulation time has passed to a point at which the prior operating instruction has been completed, and the next instruction is to be executed. The program computes elapsed time for the software and schedules the activation of the next instruction.
