47. Write a code which converts 4 bit binary to gray code? Ans : assign out = { binary[3]),(binary[3] ^ binary[2]), (binary[2] ^binary[1]),(binary[1] ^ binary[0]) }; 48. Write a code for one hot counter? Ans : always @ (posedge clk)if (reset)out <= 8'b0000_00...
This code defines a 5:1 Multiplexer (mux_5to1) with five inputs (data) and a three-bit select signal (sel). The output (out) selects one of the five inputs based on the selected signal. If the select signal doesn’t match any defined case, the output is set to an ‘X’ value...
61. 2-to-1 multiplexer Problem Statement Create a one-bit wide, 2-to-1 multiplexer. When sel=0, choose a. When sel=1, choose b. Expected solution leng
Conditional assignments: A proper conditional assignment will infer multiplexer. If the conditional assignment is not completed then it will infer latch Assign out1 = (sel == 1’b0)?in1: in2; Multiple non-blocking assignments in procedural block: If there are multiple non-blocking assignments in...

Case statements are more convenient than if statements if there are a large number of cases. So, in this exercise, create a 6-to-1 multiplexer. When sel is between 0 and 5, choose the corresponding data input. Otherwise, output 0. The data inputs and outputs are all 4 bits wide. ...
