Oct 28, 2017 · Through this post, I want to share two simple gate level Verilog codes for converting binary number to Gray and vice versa. //xor gates. The code was simulated using Xilinx ISE 14.6 tool. The following waveform verifies the correctness of both the designs. The output of binary to gray module is connected as input of gray to binary converter.

Let’s see binary numbers and their equivalent gray code in the below table. By solving using K-map technique, a simple combinational circuit turned out as. b2g_converter b2g(binary, gray); initial begin $monitor("Binary = %b --> Gray = %b", binary, gray); . binary = 4'b1011; #1; . binary = 4'b0111; #1; . binary = 4'b0101; #1; .

Simple Binary to gray conversion Data flow Model Verilog code: module bintogray (input [3:0]bin,output [3:0]gray); assign gray [3] = bin [3]; assign gray [2] = bin [3]^bin [2]; assign gray [1] = bin [2]^bin [1]; assign gray [0] = bin [1]^bin [0]; endmodule. Try this code.

Gray code is a binary code where each successive value differs from the previous value by only one bit. Implementation #1 module bin2gray #(parameter N=4) ( input [N-1:0] bin, output [N-1:0] gray); genvar i; generate for(i = 0; i N-1; i = i + 1) begin assign gray[i] = bin[i] ^ bin[i+1]; end endgenerate assign gray[N-1] = bin[N-1]; endmodule

Dec 13, 2020 · Few years back I had written a 4 bit converter for conversion between Gray and Binary codes. After receiving much positive response I decided to write a generic version of the same. Let me share the codes... Binary to Gray Code Converter:

Here’s the Verilog code for the 4-bit binary to Gray code converter: This Verilog module, b2g, takes a 4-bit binary input b and outputs a 4-bit Gray code g. The Gray code bits are generated by XORing adjacent bits of the binary input, with the most significant bit (MSB) remaining the same.

For binary to gray, it uses a case statement to assign the 4-bit gray code outputs based on the 4-bit binary inputs. For gray to binary, it uses XOR gates to calculate the binary outputs from the gray inputs. For BCD to gray, it again uses XOR gates to convert the 4-bit BCD to gray code.

We’ll now focus on implementing a 4bit Binary-to-Gray a Gray-to-Binary converter using Verilog and Modelsim Intel FPGA Edition. Watch this simple, practical video and implement the Gray encoder / decoder and a testbench for them in no time! Download the files.
