Abstract
Range information is determined for each variable of a circuit design. The range information is propagated from inputs to outputs of nodes of a DFG representation of the circuit design. For each multiplexer of the circuit design represented as a multiplexer node in the DFG, whether range information associated with a selector input of the multiplexer node restricts selection of data inputs of the multiplexer node to only one selected data input of the multiplexer node is determined. In response to determining that range information associated with the selector input restricts selection of data inputs to only one data input, the DFG is modified by connecting the selected data input to each load of the multiplexer node, and removing the multiplexer node, a corresponding select logic node of the multiplexer node, and nodes connected to unselected data inputs of the multiplexer node.
