FORCE_CONFIGURATION_VCCIO
FORCE_CONFIGURATION_VCCIO
Type
Forces the V CCIO voltage of the configuration pins to be the same as the configuration
device I/O voltage.
In some device families, the V CCIO of some banks power both general purpose I/Os
and configuration pins.
Turning on this option forces the Fitter to produce an I/O placement in such a way
that the V CCIO would be consistent with the selected configuration voltage.
Fitter produces placement errors if such I/O placement cannot be found.
