4x1 Mux. Testbench for 4 1 mux using verilog a testbench is an hdl code that allows you to provide a set of stimuli input to test the functionality and wide range of plausible inputs for support to a system. This truth table can be simplified by the vem.
Its output is one of the four inputs depending on the selections. Mux tree basic 4x1 mux using 2x1 mux easy explanationcontribute. The block diagram of 4x1 multiplexer is shown in the following figure.
The multiplexer will select either a b c or d based on the select signal sel using the case statement.
The multiplexer will select either a b c or d based on the select signal sel using the case statement. Both types of multiplexer models get synthesized into the same hardware as shown in the image below. This truth table can be simplified by the vem. The truth table for a 4x1 mux.
