Complete computer system simulation: the SimOS approach

SimOS is a simulation environment capable of modeling complete computer systems, including a full operating system and all application programs that run on top of it. Two features help make this possible. First, SimOS provides an extremely fast simulation of system hardware, and the second feature that enables SimOS to model the full operating system is its ability to control the level of simulation detail. Designed for efficient and accurate study of both uniprocessor and multiprocessor systems, SimOS simulates computer hardware in enough detail to run an entire operating system and provides substantial flexibility in the tradeoff between simulation speed and detail
