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...
(a) write a Verilog description of the circuit shown below module Circuit (F, A, A_bar, B, B_bar, C, D_bar); ……….. Endmodule (b) Write a Verilog description of the circuit specified by the following Boolean function: Z = (A + B’)C’(C + D) AB AB CD
Q3. Draw the circuit represented by this Verilog code Module system(A,B.C.Y) Input A,B.C: Output Y Assign Y (C1)?A: B 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
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...
Write a test bench to thoroughly test the Verilog module dff_fe_asyn_h. below is the module ddff_fe_asyn_h.code Simulate the circuit using ISim and analyze the resulting waveform. Verilog Code for dff_fe_asyn_h is mentioned below:- //DFF module with asynchronous active high reset with negative edge trigger with clock module dff_fe_asyn_h ( input clock, // Clock Input input reset, // Reset Input input data_in, // Input Data output reg data_out // Output Data ); always @ (negedge clock or posedge reset) // triggers...
Please explain what he verilog code does: module lab7_2_3( input clk, input Enable, input Clear, input Load, output [3:0] Q, reg [3:0] count, wire cnt_done ); assign cnt_done = ~| count; assign Q = count; always @(posedge clk) if (Clear) count <= 0; else if (Enable) if (Load | cnt_done) count <= 4'b1010; // decimal 10 else count <= count - 1; Endmodule
