Create the Decoder module in System Verilog to decode the 4-bit Binary Coded Decimal digit into seven-segment code. You can also include and instantiate your decoder schematic from Section 3 instead of writing a new System Verilog module.

VERILOG CODE

module bcd_7segment(BCD,clk, segment);
input [3:0] BCD;
   input clk;   //inputs ABCD
output reg [6:0] segment;   //segments abcdefg

always @ ( posedge clk)
begin
case (BCD)
    4'b0000 : begin segment = 7'b1111110; end   //BCD 0
4'b0001 : begin segment = 7'b0110000; end//BCD 1
4'b0010 : begin segment = 7'b1101101; end   //BCD2

Create the Parser module in System Verilog to convert the 8-bit Button Board input into four 4-bit Binary Coded Decimal numbers. The parser should read in an 8-bit Button Board input as an 8-bit number (0-255). Parse that 8-bit number into four 4-bit numbers (0-9) representing its ones, tens, hundreds, and thousands digit.

Question B Write an 8 bit adder module in System Verilog by appropriately connecting two 4 bit adders (the System Verilog code of a 4 bit adder is available in the lecture notes). Instantiate your 8 bit adder module on DE2 board. Design a test circuit on DE2 board that allows us to test the 8 bit adder using the switches and the seven segment displays on DE2 board. The test circuit will need the module you designed for Part...

Model a BCD to 7-Segment Decoder (1111 1000) Create a top-level Verilog module, named bcdto7segment_dataflow with 4-bit data input (x[3:0]), anode enable output signals (an[3:0]), and 7-bit output (seg[6:0]) using dataflow modeling (Hint: You will have to derive seven expressions for the 7 segments on paper). Assign appropriate logic to an[3:0] in the model so you can display only on the right most display.

You are using a poorly constructed 4-bit natural binary-coded absolute encoder and observe that, as the encoder rotates through the single step from code 3 to code 4, the encoder outputs several different and erroneous values. If misalignment between the photosensors and the code disk is the problem, what possible codes could result during the code 3-to-4 transition?

Verilog counter problem: Using the attached 4-bit up-counter module and testbench as a template, write a Verilog module that implements a certain 4-bit counter. The module should include two more input variables: “updown” and “count2”. If “updown” is 1, the circuit should count up (by 1s); if it is 0 it should count down (by 1s). If “count2” has a value of 1, the circuit should instead count up by 2s; otherwise it will have no effect (the circuit counts...
