August undefined, 2024

WebbPlacement time forms a large part of the compile time. The most popular method for placement is simu- lated annealing. The Versatile Place and Route (VPR) tool [13], one of the leading tools in academia uses simulated annealing for placement and can be used to place a wide range of FPGA architectures. WebbApplication of simulated annealing to solve this optimization problem yields the following results. Table (1) shows the optimum design variable values and the optimum cost of the beam
