3. From the slides and the reference materials, we see that there are two methods for implementing logic in Verilog HDL. The circuit can be described using "Structural Verilog or "Behavioral Verilog." In Structural Verilog the structure of the circuit is defined using Boolean algebra statements. In Behavioral Verilog the circuit is defined by its behavior. Below are examples of a 2x1 multiplexer implemented using structural and behavioral Verilog. STRUCTRAL 2x1 MULTIPLEXER CODE: // Example 5a: 2-to-1 MUX using logic...

Write Verilog modules: a 3x8 decoder and a 8x1 multiplexor. The multiplexor “includes” the decoder module as part of it. Use arrays as much as possible. EXAMPLE: module DecoderMod(s, o); // module definition input s; output [0:1] o; not(o[0], s); assign o[1] = s; endmodule module MuxMod(s, d, o); input s; input [0:1] d; output o; wire [0:1] s_decoded, and_out; DecoderMod my_decoder(s, s_decoded); // create instance and(and_out[0], d[0], s_decoded[0]); and(and_out[1], d[1], s_decoded[1]); or(o, and_out[0], and_out[1]); endmodule

Write a behavioral Verilog module for a 4-bit Johnson counter that has 8 states. The counter loads the "0000" state if reset is low. The counter should start and end with this state. Write a testbench to verify the correctness of the 4-bit Johnson counter. The testbenclh should have a clock with a period of 20ns and a reset signal. The testbench should store the 4-bit binary outputs of the counter in a file, which will be used to provide...
