This lab is designed to introduce Verilog and waveform simulations. You are to design 4 small modules and prove that they work properly using waveform simulations. 1. 4-to-1 Multiplexor Figure 1-1: Part 1 2. 1-to-4 Demultiplexor D1 D2 D3 S0,S1) Figure I-2: Part 2 This lab is designed to introduce Verilog and waveform simulations.
