It is obvious that a multiplexer is used to select one of several input signals; however, in this white paper, I will consider a variety of ways in which multiplexers can be implemented within Xilinx FPGA devices. First, I will consider the straight forward method and identify some potential issues. We will then investigate some alternative techniques that can lead to more efficient and lower cost implementations. In your future designs, you will be able to consider your multiplexer selections in order to select signals. White Paper: Xilinx FPGA Families
