AR# 40954: 12.4 PlanAhead - Open project results in "ERROR: [#UNDEF] File not found: /runs.xml"
12.4 PlanAhead - Open project results in "ERROR: [#UNDEF] File not found: /runs.xml"
I open a project and the following error occurs:
"ERROR: [#UNDEF] File not found: <PATH>/runs.xml"
This error occurs if the project and runs directory content get out of sync. Usually, this happens on Windows when some process keeps a lock on the <project>.runs directory (e.g., antivirus programs). In these situations, you typically see that the <project>.runs directory contents have been emptied out, but the "runs" directory itself could not be deleted. Instead, the most recent data would be stored in a runsXX directory (see below).
In ISE Design Suite 13.1, automatic recovery mechanisms have been added to get around this issue.
In 12.x, the following work-around can be used:
When the project fails to open with the error message stated, exit PlanAhead completely without any further operation.
Using Windows Explorer (or command shell), go to the <project> directory.
You might see one or more <project>.runsXX directories (runs1, runs2, runs3 etc.).
Rename the current <project>.runs directory to something else (e.g., <project>.runs_deleted).
Select the highest numbered <project>.runsXX directory, and rename it to <project>.runs.
Launch the PlanAhead tool and open the project again (it should open fine this time).
