This code defines a 5:1 Multiplexer (mux_5to1) with five inputs (data) and a three-bit select signal (sel). The output (out) selects one of the five inputs based on the selected signal. If the select signal doesn’t match any defined case, the output is set to an ‘X’ value...
The rtl code is elaborated to get a hardware schematic that represents a 4 to 1 multiplexer. See that output is zero whenselis 3 and corresponds to the assigned inputs for other values. Simulation Log ncsim> run [0] a=0x4 b=0x1 c=0x1 sel=0b11out=0x0[10] a=0x5 b=0x5c=0x5se...
