A statistically rigorous approach for improving simulation methodology

J.J. Yi, D.J. Lilja, D.M. Hawkins
The Ninth International Symposium on High-Performance Computer Architecture, 2003. HPCA-9 2003. Proceedings.  
A formal methodology can provide a sound basis for drawing conclusions gathered from simulation results by adding statistical rigor and, consequently, can increase confidence in the simulation results.  ...  However, despite this continued dependence on simulators, statistically rigorous simulation methodologies are not typically used for computer architecture research.  ...  To improve the methodology of the first stage, we describe a statistically rigorous method of choosing the values of the processor parameters.  ...
