Cannot Run Autorouter on MacOS about freerouting HOT 1 CLOSED

I think I figured out what's going on.

In my DSN file, I use autoroute_settings.

When I change (start_pass_no 1) to (start_pass_no 0), the autorouter runs one pass (pass 0) and stops.

By reading the source code, I think the set_stop_pass_no method is never called, the stop pass number remains 0.

I have inserted the instruction result.set_stop_pass_no (99999); in the AutorouterSettings.java:

                else if (next_token == Keyword.START_PASS_NO)
                {
                    result.set_start_pass_no(DsnFile.read_integer_scope(p_scanner));
                    result.set_stop_pass_no (99999);
                }

And now the autorouter runs as expected.

I agree that this is not the best place to add the instruction, but it may help you solve this bug.
