I defined the result variable in the function in the tb module.
When I initialize this variable with 0 value, I face with this Error:
(vlog-2244) Variable ‘result’ is implicitly static. You must either explicitly declare it as static or automatic
or remove the initialization in the declaration of variable.
Why I can’t initialize this variable?
function int do_compare(byte_que h, byte_que g);
int result = 0;
int sum_err;
if(h.size() != g.size())begin
$display("Error in cut functions");
end
else if(h.size() == 0) begin
$display("output file is completely different from input file");
end
else begin
foreach(h[i])
if(h[i] != g[i])begin
sum_err++;
end
result = (h.size()-sum_err)/h.size()*100;
end
return result;
endfunction
