1.10.4. ALLOW_LVTTL_LVCMOS_INPUT_LEVELS_TO_OVERDRIVE_INPUT_BUFFER

Specifies whether the Fitter allows input pins with LVTTL or LVCMOS I/O standards to be placed inside an I/O bank with a lower VCCIO voltage than the voltage specified by the pins. Overdriving the I/O bank results in higher leakage current, which can cause the design to not function as intended.
