Characterizing and Comparing Prevailing Simulation Techniques
Due to the simulation time of the reference input set, architects often use alternative simulation techniques. Although these alternatives reduce the simulation time, what has not been evaluated is their accuracy relative to the reference input set, and with respect to each other. To rectify this deficiency, this paper uses three methods to characterize the reduced input set, truncated execution, and sampling simulation techniques while also examining their speed versus accuracy trade-off and configuration dependence. Finally, to illustrate the effect that a technique could have on the apparent speedup results, we quantify the speedups obtained with two processor enhancements. The results show that: 1) The accuracy of the truncated execution techniques was poor for all three characterization methods and for both enhancements, 2) The characteristics of the reduced input sets are not reference-like, and 3) SimPoint and SMARTS, the two sampling techniques, are extremely accurate and have...
