| 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? |

| 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. |
