A computer system simulation method starts with algorithmically implementing a specification model independently of hardware architecture. High level functional blocks representing hardware components are connected together using a bus architecture-independent generic channel. The bus architecture-independent generic channel is annotated with timing and protocol details to define an interface between the bus architecture-independent generic channel and functional blocks representing hardware components. The interface is refined to obtain a CCATB for communication space. The read( ) and write( ) interface calls are decomposed into several method calls which correspond to bus pins to obtain observable cycle accuracy for system debugging and validation and to obtain a cycle accurate model. The method calls are replaced by signals, and the functional blocks representing hardware components are further refined to obtain pin/cycle-accurate models which can be manually or automatically mapped to RTL, or be used to co-simulate with existing RTL components.
