Logic-Physical-Aware Benchmark Suite

The Logic-Physical-Aware Benchmark Suite enables to jointly consider logic synthesis and physical design. From educational and benchmarking standpoints, this benchmark suite is intended to break the barrier between logic synthesis and physical design. The set of benchmarks proposed herein can be used to achieve two major purposes: (1) to consider physical information during the early steps in design flow, which makes possible to perform a draft design closure during logic synthesis; and (2) to regard logic features while handling physical designs, which allows investigations about resynthesis approaches by collapsing/splitting logic cells in such a way to obtain more physical-friendly designs. The initiative presented herein is an early move towards more comprehensive benchmarks, by adding specific files with physical information and timing requirements to existing logic synthesis benchmarks.

Much has still to be done, e.g. add larger benchmarks. However, this first initiative identifies the lack of benchmarks that would serve to both logic synthesis community, which attend the International Workshop on Logic and Synthesis (IWLS), and physical design community, which attend the International Symposium on Physical Design (ISPD). This is a first, naive set of benchmarks aiming the use and discussions by both communities, in order to capture a more comprehensive list of requirements for a more complete benchmark suite, which fulfils requirements of logic synthesis and physical design.
