General Description:
Although I have selected several I/O configuration options from the Ports tab, the option to change the IOSTANDARD column is not available for any ports.
To work around this problem, hand-edit the UCF with the following syntax:
INST "<ibufg_or_bufg_inst_name>" IOSTANDARD= <io_standard>;
