Abstract

Fast FPGA CAD tools that produce high quality results has been one of the most important research issues in the FPGA domain. Simulated annealing has been the method of choice for placement. However, simulated annealing is a very compute-intensive method. In our present work we investigate a range of parallelization strategies to speedup simulated annealing with application to placement for FPGA. We present experimental results obtained by applying the different parallelization strategies to the Versatile Place and Route (VPR) Tool, implemented on an SGI Origin shared memory multi-processor and an IBM-SP2 distributed memory multi-processor. The results show the tradeoff between execution time and quality of result for the different parallelization strategies.
