5.1i PACE - A "Check Pin Assignment" operation with valid I/O standards specified leads to an error stating "The I/O standard specified is not supported"


Keywords: PACE, check pin, error, I/O , IO, standard, support, interactive DRC

Urgency: Standard

General Description:
After I enter a valid I/O standard in the DOL window, I cannot place the I/O in the architecture or package window. When I perform a "Check Pin Assignment" operation, an error reports

"Write_enable: The I/O standard specified is not supported."


While lowercase characters are supported by the UCF file and DOL window, they are not accepted by the DRC check.

To work around this problem, either use the drop-down window to specify the I/O standard in the DOL window, or enter the I/O standards using uppercase characters.
