6.1i FPGA Editor - In windows, double-clicking NCD file opens FPGA Editor but not the NCD file


Keywords: FPGA, Editor, open, NCD, click, windows, read, file, error

Urgency: Standard

General Description:
In Windows Explorer, if you double-click an NCD file, the FPGA Editor GUI is open, but instead of opening the NCD file, the following error message occurs:

"Error: FPGA Editor - Unable to read file "/dde.ncd"
Check path name and file permissions."


To work around this, you can generally do the following:

1. Open "Window Explorer" .
2. Click "Tools -> Folder Options". Then click the "File Types" tab.
3. Look for "NCD" as a registered extension type. Once it is selected, click the "delete" button.
4. Still under the "File Types" tab, click New button to open the "Create New Extension" window.
5. Type "NCD" in the box and click OK. This brings you back to the "File Types" tab in the "Folder Options" window.
6. Now select "NCD" from "Registered File Types".
7. Click the "Advanced" button at the bottom. Click the "New" button to open the "New Action" window.
8. Type "open" in the Action entry.
9. For the "Applications used to perform this action" browse to "%xilinx%\bin\nt\fpga_editor.exe" and select it for the entry. Also add a space and %1 after "fpga_editor.exe". The "Applications used to perform this action" entry should look like this:
C:\Xilinx6.3\bin\nt\fpga_editor.exe %1
10. Leave "Use DDE" Unchecked. Click OK.
