Pattern generator- verilog code
This must be coded in verilog
In this assignment we will program a sequential circuit in Verilog code as a pattern generator which generates, instead of binary counts, your Firstname (space) Lastname (space), character by character. Display the pattern sequence for at least two cycles (run the demo).
Suppose the output of the ripple sequencer is an arrray of q. Then, the truth table of encoding is:
q0 q1 q2 q3 q4 ... ascii[6:0] char 1 0 0 0 0 ... 101 0111 = 'W' 0 1 0 0 0 ... 110 0101 = 'e' 0 0 1 0 0 ... 110 1001 = 'i' 0 0 0 1 0 ... 110 0100 = 'd' 0 0 0 0 1 ... 110 0101 = 'e' (etc.)
Below is the code, the CoderMod module is the only one that needs to be completed. The size of the arrays in the other 2 modules might need to be adjusted. Please use "First [space] Lastname" for the name in the ascii code.

module TestMod;
reg CLK;
wire [0:11] Q;
wire [6:0] ascii;
initial begin

CLK=0;

end
RippleMod my_ripple(CLK, Q);
CoderMod my_coder(Q, ascii);
initial #27 $finish;
initial begin
$display("Time CLK Q Name");
$monitor("%4d %b %b %c %x %b", $time, CLK, Q, ascii, ascii, ascii);
end
endmodule
module CoderMod(Q, ascii);
...
endmodule
module RippleMod(CLK, Q);
input CLK;
output [0:15]Q;
reg [0:15]Q;
always @(posedge CLK) begin

Q[7]
Q[8]
Q[9]
Q[10]
Q[11]
Q[12]
Q[13]
Q[14]
Q[15]
end
initial begin
Q[0] = 1;
Q[1] = 0;
Q[2] = 0;
Q[3] = 0;
Q[4] = 0;
Q[5] = 0;
Q[6] = 0;
Q[7] = 0;
Q[8] = 0;
Q[9] = 0;
Q[10] = 0;
Q[11] = 0;
Q[12] = 0;
Q[13] = 0;
Q[14] = 0;
Q[15] = 0;
end
endmodule
