Simulating Your Design
This difference is the first argument.
You can let VCS do some of this work for you by using the following
source code:
module wide_time;
time wide;
initial
begin
wide = 64’d10_000_000_000;
$display(“Hi=%0d, Lo=%0d”, wide[63:32], wide[31:0]);
end
endmodule
VCS displays:
Hi=2,Lo=1410065408
2. Divide the large time value by 2
32
.
In this example:
3. Round down this quotient to the whole number. This whole
number is the second argument.
In this example, you round down to 2.
You now have the first and second argument. Therefore, in this
example, to specify stopping simulation at time 10,000,00,000 you
enter the following runtime option:
+vcs+stop+1410065408+2
10 000 000 000,,,
4 294 967 296,,,
