Cannot Run Autorouter on MacOS

[pierremolinaro]

Freerouting version: 1.4.4
Platform: MacOS Mojave, MacOS ElCapitan, other MacOS ?
Can you attach the actual (DSN) file? Yes, see below. I have tried different files, always the same behaviour.
Did you use any command line arguments -> No
Please list the detailed steps to reproduce the problem
Open the design.dsn file with Open Your Own Design button. Ok.
Click on Autorouter button. Immediately, it displays Autoroute interrupted, 15 connections not found. Autorouting is not performed.

DSN file (I have appended the txt extension in order to be able to attach the file) :

design.dsn.txt

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.
