Abstract
A processor performance evaluation system and method provides a method of model decomposition and trace attribution by first decomposing a full pipelined model of the entire system into a main model and one or more additional sub-models, such that it is possible to build fast trace-driven non-pipelined simulation models for the sub-models to compute specific metrics or values, which would be required during full-model, pipeline simulation. The main model is a fully pipelined model of the entire system; however, the simulation work required for the sub-units characterized by the sub-models is not coded into the simulation engine. Instead, the necessary values are provided from encoded fields within the input trace.
