13.4 PlanAhead - "An internal exception has been detected. PlanAhead may be in an unstable state."

Description

When I attempt to open a PlanAhead toolproject, the following error occurs:

"An internal exception has been detected. PlanAhead may be in an unstable state."

Solution

This can happen when a drive is mapped and there is a shortcut to the drive on the desktop.

To work around the issue, you can remove the link from the desktop and open up the PlanAhead tool.

Alternatively, if you want to retain the link, then follow these steps to open the project using Tcl:

  1. Open a command prompt.
  2. Change the directory to: C:\Xilinx\12.4\ISE_DS\Planahead\bin.
  3. Type planahead -mode tcl and press Enter.
  4. Type "open_project %path%/my_project.ppr" where %path% is the path to the project file.
    For example:"c:/training/ADV_PlanAhead/labs/projects/design_analysis/project_cpu_netlist/project_cpu_netlist.ppr".
  5. Type start_gui to start up the GUI.

This issue is scheduled to be resolved in the PlanAhead 14.1 software.
