Abstract
This paper develops a new model of parameter varia- tins for use in early-stage, pre-RTL architecture studies. It improves over prior models by extending the FMAX model to more faithfully model various microarchitecture struc- tures, especially SRAM, which is dominant in contempo- rary superscalar processors. It also incorporates optical phenomena, which show strong spatial correlation but nev- ertheless cannot be ignored for large dies. Finally, it incor- porates IR Vdd drop and temperature, and closes all these feedback loops to obtain converged estimates of frequency, leakage, voltage, and temperature. With this model, we ex- plore PVT limitations on multi-core integration and the dif- ficulties in obtaining matched cores.
