4.3.1.4. IOSTANDARD
Equivalent to the IOSTANDARD constraint in Xilinx* , the IO_STANDARD logic option uniquely defines the input and output (VCCIO) voltage, reference VREF voltage (if applicable), and the types of input and output buffers used for I/O pins.
The following example shows how to set the equivalent IOSTANDARD constraint (Differential SSTL-2 Class I) to the “q2” output.
Example XDC command:
# Set Differential SSTL18_I I/O Standard to q2
set_property IOSTANDARD SSTL18_I [get_ports q2];
Equivalent QSF command:
# Set Differential SSTL-18 Class I I/O Standard to q2
set_instance_assignment -name IO_STANDARD "SSTL-18 CLASS I" -to q2
