ANUBIS: A New Benchmark for Incremental Synthesis

Synthesis, placement, and routing turnaround times are some of the major bottlenecks in digital design productivity. Engineers usually wait several hours to get accurate results to design changes that are often quite small. Incremental synthesis has emerged as an attempt to reduce these long times, but research in incremental synthesis currently lacks a consistent benchmark to enable comparison between different flows and that is reflective of real design changes. In this paper, we propose ANUBIS, a benchmark for incremental synthesis based on real designs and real design changes. ANUBIS comes with a standard score that allows for easily comparing different flows. We evaluate ANUBIS using two incremental commercial flows to give insights on its usage and reporting.
