In this paper, we describe the application of two parallelization strategies to the Quartus II FPGA placer. The first uses a pipelining approach and achieves speedups of 1.3x on two processing cores. The second uses a parallel moves approach and achieves speedups of 2.2x on four cores. Unlike all previous parallel moves algorithms, ours is deterministic and(More)
We describe a parallel simulated annealing algorithm for FPGA placement. The algorithm proposes and evaluates multiple moves in parallel, and has been incorporated into Altera’s Quartus II CAD system. Across a set of 18 industrial benchmark circuits, we achieve geometric average speedups during the quench of 2.7x and 4.0x on four and eight processors,(More)
