“…Recently, placement test suites that include fictitious geometry reproducing the essential challenges of real fabrication geometry were released [5], [6]. The availability of these benchmarks will bring quicker discovery of faster and better placement algorithms optimizing towards the real routability.…”

“…There are efforts in modeling congestion and routability with some probabilistic metrics, but there is not yet any simple metric that is shown to be correlated directly to the final routability. Routability-driven placement becomes a hot topic in recent years and a series of routability-driven placement contests were organized in different conferences (ISPD 2011 [2], DAC 2012 [3], ICCAD 2012 [4], ISPD 2014 [5], ISPD2015 [6]) to promote research in this field.…”

“…This way, the logic synthesis academic community is stimulated to disregard physical information. From the point of view of the physical design community, academic benchmarks [12][13][14][15][16][17][18][19][20][21][22] are distributed without information about the logic inside the blocks. This way, the physical design academic community is stimulated to disregard the possibility of logic transformations.…”

This paper presents an improved benchmark suite to jointly consider logic synthesis and physical design. Usually, benchmark circuits were provided by the physical design and the logic synthesis communities separately, according to their specific needs. The files provided for each benchmark set were restricted to the views necessary for the community. Additional specifications of design intents are necessary to express optimization goals that can be shared by logic synthesis and physical design communities, as circuits alone do not carry sufficient information to establish a benchmark with a clear optimization goal. In this paper, we describe benchmarks as a set composed of circuits, design intents (constraints), floorplan, target library and technology. Disregarding pieces of information provided for the benchmarks can change the associated criticality and affect the combined or isolated outcome of logic synthesis and physical design. The proposition of this benchmark suite brings attention to the problem of considering adequately the complete context of design intent throughout the flow.
