Generating New Benchmark Designs for Evaluation of Cad Tools and New Computer Architectures Generating New Benchmark Designs for Evaluation of Cad Tools and New Computer Architectures

The development of better CAD-tools for the layout, placement and routing of digital designs requires a huge amount of benchmark circuits to evaluate the new tools extensively. Benchmarks are also needed for the design of new computer hardware. Observing the lack of enough real benchmark designs for use in evaluation tools, one could consider to actually generate such benchmarks. In that case, it is very important that those generated benchmarks have the same characteristics as real designs. This paper describes and evaluates a new benchmark generation procedure that produces benchmarks with characteristics, similar to those of real benchmark designs. It will be shown that this new technique outperforms an existing method, presented by Darnauer and Dai DD96].
