US Patent 7308393 Hardware and software co-simulation using estimated adjustable timing annotations

A system and method for co-simulation of hardware and software includes determining hardware executable times, associated with each of a plurality of functions included within an application code. Estimated timing annotations, which correspond to the determined hardware executable times, are then inserted into each of the functions. The application code is compiled for simulation and the compiled application code is then executed on a host computer system. Adjustments may be made to the estimated timing annotations to evaluate potential architecture changes in either target hardware or software algorithms.
