In this paper, a novel strategy for designing the heterogeneous tree multiplexer is proposed. The authors build the multiplexer delay model by curve fitting and then formulate the heterogeneous tree multiplexer design problem as a special type of optimization problem called mixed-integer nonlinear programming (MINLP). A new design parameter, the switch size in each stage, is introduced to improve the speed of the heterogeneous tree multiplexer. The proposed strategy can determine the multiplexer architecture and the switch size in each stage simultaneously. Three optimization methods are provided to synthesize the heterogeneous tree multiplexer according to the design specifications.
