Executive Summary

With the advent of large scale chip-level multiprocesssors, there is renewed interest in the design and analysis of on-chip networks. The use of full system simulation is the most accurate way to perform such an analysis, but unfortunately it is very slow and thus limits the design space exploration. In order to overcome this problem researchers frequently use trace based simulation to study different network topologies and properties, which can be done much faster.
