Description

Solution

This error occurs if the PlanAhead project and the actual directory structure are out of sync, in that the project (and data files) indicates no run, but the synth_1 folder is on disk.

The message indicates that the directory could not be created because there is already a directorywith that name for synthesis process(directory <path>/synth_1) and the tool does not expect tofind it there.

To fix the problem, you will need to rename or remove this directory and re-run the synthesis process.

In PlanAhead 13.3, the message has been changed to the following:

[Runs-51] Unable to write to run directory <path>/synth_1. Please manually rename or remove this directory and try this operation again.
