why its 4-to-1 mux behavioral?
What does the logic circuit represented by the following Verilog module do, and what Verilog description style does it use? // My Verilog module #1 module mymodl ( x, d, q) input[1:0] x;input[3:0] d;output q; reg q; wire [1:0] x; wire [3:0] d; always ( x or d) begin case ( x ) 1 : q=d[1]; 2 : g=d[2]; 3 q d[3]; endcase end endmodule

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

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...
