The SPEC benchmark system has traditionally been used for evaluating computer architectures. However, this system is too general and does not accurately reflect the performance of architectures on domain-specific applications. Moreover the CPU95 benchmark suite used in the SPEC system is compute-intensive, while many important domains of applications have memory intensive algorithms. In this work, we present a benchmarking methodology for such an application domain-CAD for VLSI design. We have created a benchmark suite consisting of CAD applications from each stage in a typical VLSI design flow. To exercise the memory organization, each application is run on a sequence of input designs of increasing size. We observed that increasing the input size causes non-monotonic variations in the performance of different machines. We simulate the caches of the benchmarked architectures to assess the effect of memory organization on performance
