Multilevel simulation-based co-design of next generation HPC microprocessors

This paper demonstrates the combined use of three simulation tools in support of a co-design methodology for an HPC-focused System-on-a-Chip (SoC) design. The simulation tools make different trade-offs between simulation speed, accuracy and model abstraction level, and are shown to be complementary. We apply the MUSA trace-based simulator for the initial sizing of vector register length, system-le...
