Abstract

When proposing new architectural enhancements, it is also important to account for the hardware complexity. To achieve this goal, we propose to model the new design in a hardware description language (HDL), synthesize the HDL code, and infer a realistic clock cycle which will be used in subsequent simulations. For accurate results, we develop a two-level hierarchical simulation technique, where an execution driven simulator (RSIM) and an HDL simulator (Verilog-XL) are coupled to evaluate an entire system. We detail the simulation process and show its impact on the design of an interconnect switch architecture for CC-NUMA multiprocessors.
