An improved placement and routing method for circuit simulation includes receiving setup input controls to set up an initial arrangement of two blocks (e.g., a synthesized block and an IP block), and a designation of permutable interconnections; performing permutations of permutable interconnect signals on the, e.g., design block (or any other block)-IP block arrangement to determine an optimal permutation; compiling a bitstream comprising a final placement and route of a circuit based on the optimal permutation and generating the bitstream to be loaded onto a target FPGA; and sending the final order of the permutable signals to a permutable signals control memory structure.

Reconfigurable connections

Configuring a hardware system includes providing a first data representative of a first assignment of a multitude of wires to a multitude of physical connections between a multitude of logic circuits of the hardware system, and transforming the first data into a second data representative of a second assignment of the multitude of wires to the multitude of physical connections. The transforming includes calculating a multitude of latencies each associated with a selected one of the multitude of wires, and assigning a first subset of the multitude of wires to at least one of the multitude of physical connections in accordance with a first improvement goal. The transforming causes the value of each one of the multitude of latencies that are associated with the first subset to be less than or equal to the first improvement goal, when the second data is used to configure the hardware system.
