10.1 ISE - FPGA Editor does not open when I select "Open Without Updating"
When I right-click the "View/Edit Routed Design (FPGA Editor)" process and select "Open Without Updating", nothing happens.
This happens when the Place and Route (PAR) has not been run successfully, or if a Cleanup Project Files process has been run after the last successful PAR run.
The "View/Edit Routed Design (FPGA Editor)" process should be greyed out when the process is not available rather than appearing to be available and silently failing.
This problem has been fixed in the latest 10.1 Service Pack available at:
The first service pack containing the fix is 10.1 Service Pack 1.
