MODIFYING A VIRTUAL PROCESSOR MODEL FOR HARDWARE/SOFTWARE SIMULATION

A method of transforming a provided virtual processor model to a user virtual processor model. Also a tool, e.g., provided as instructions for operating in a host computer system for converting a provided virtual processor model to a user virtual processor model. Also a method of specifying one or more characteristics of a target processor to transform a provided virtual processor model to a user virtual processor model that when operating in a c-simulation system, simulates the operation of the target processor. For example, a method of specifying one or more characteristics of instructions to transform a provided virtual processor model to a user virtual processor model.
