Abstract
A method and apparatus for improving the interconnection and multiplexing cost of circuit design from high level synthesis using ant colony optimization is described. In one example, a plurality of hardware components for performing an operation is represented with a data flow graph having edges and nodes. A plurality of solutions are simulated for performing the operation as hardware component and schedule combinations represented as paths on the data flow graph. For each solution, cost including a number of edges and nodes traversed on the data flow graph and an interconnection cost related to the number of different hardware components in the path is determined. A pheromone trail is associated with each path, the pheromone trail including a cost of the respective scheduling solution, and a solution is selected with the highest value pheromone trail as a hardware component and schedule combination for a circuit.
