Why run into the following test results inaccurate?
//first p
module real_number;
parameter a=1.2;
parameter b=1.5;
assign c=a+b;
initial begin
$display ("result is:",c);
# 10 $finish;
end
endmodule
result: x
but when running the program:
module real_number;
parameter a=1.2;
parameter b=1.5;
//assign c
initial begin
$display ("result is:",a+b);
# 10 $finish;
end
endmodule
we obtain accurate results: 3.7
if you want to write the program first, then how to write?
thanks!!!
