Question

Develop a testbench for the following parity checker

module parity checker(
input [7:0] bitt,
output reg ans
);

integer count = 0;
integer i = 0;

always@(bitt)
begin
count = 0;
for(i=0; i<=7; i=i+1)
begin
if(bitt[i]==1)
count = count + 1;
end
if(count%2==0) //even parity
ans = 1;
else
ans = 0;

end

endmodule

Verify the testbench using the following numbers: 0, 5, 86, 111.

Type out your testbench code and verify that it works using a computer program (modelsim or EDA playground)
