CONFIGURATION_VCCIO_LEVEL
CONFIGURATION_VCCIO_LEVEL
Type
Specifies the V CCIO voltage of the configuration pins for the current configuration
scheme on the target device.
Some configuration schemes support multiple configuration voltage levels. This
option allows you to specify a configuration voltage level.
The Fitter produces warnings if the configuration voltage level is not consistent with
the V CCIO after the I/O placement.
You can use the FORCE_CONFIGURATION_VCCIO option to force the V CCIO voltage
of the configuration pins to be the same as the configuration device I/O voltage.
