Abstract:

In this paper, we present FastPlace 2.0 - an extension to the efficient analytical standard-cell placer - FastPlace, to address the mixed-mode placement problem. The main contributions of our work are: (1) Extensions to the global placement framework of FastPlace to handle mixed-mode designs. (2) An efficient and optimal minimum perturbation macro legalization algorithm that is applied after global placement to resolve overlaps among the macros. (3) An efficient legalization scheme to legalize the standard cells among the placeable segments created after fixing the movable macros. On the ISPD 02 mixed-size placement benchmarks, our algorithm is 16.8times and 7.8times faster than state-of-the-art academic placers Capo 9.1 and Feng-shui 5.0 respectively. Correspondingly, we are on average, 12% and 3% better in terms of wirelength over the respective placers
