| I am using a custom macro placement script. Changing the macro position from default to any other formation causing error in detailed routing. | |
| `[ERROR DRT-0255] Maze Route cannot find path of net (some net) in worker of routeBox (34000 75000) (41000 45000)` | |
| Is it an algorithm error, any idea? | |

| Is automatic macro placement creating that error? | |
| ### maliberty | |
| This is a problem in detailed routing that would require a test case to investigate. Can you provide one? | |
| ### maliberty | |
| I don't expect this error from the router even with a bad macro placement. | |

| How do you do custom macro placement? | |
| ### maliberty | |
| It would be great to have a test case for this problem as is so we can fix it in addition to any workarounds in placement to avoid it. | |
