| I would like to iterate on the floorplan of the top level of our design. In doing so, I want to change the pin constraints for the macros used at the top level. | |
| However, ```make generate_abstract``` goes all the way to detailed routing before producing a .gds, .lef and .lib file. This takes a long time. | |
| Is there a way to run generate_abstract after IO pin placement on the macro without going through detailed route? | |

| The flow itself doesn't have a mechanism but the command should work at that point (though it hasn't been tested). You could add a flow option if needed. | |

| Solution implemented: `make skip_cts skip_route generate_abstract` | |
