4.3.1.3. IOB
Equivalent to the IOB constraint in Xilinx* , the FAST_INPUT_REGISTER and FAST_OUTPUT_REGISTER logic options directs the Compiler to implement an input register and output register in an I/O cell that has a fast, direct connection from an I/O pin.
The following example shows how to set the equivalent IOB constraint to the input “d1” or the output “q1”.
Example of XDC command:
# Set IOB to input d1
set_property IOB TRUE [get_ports d1];
# Set IOB to output q1
set_property IOB TRUE [get_ports q1];
Equivalent QSF command:
# Set FAST_INPUT_REGSITER to input d1
set_instance_assignment -name FAST_INPUT_REGISTER ON -to d1
# Set FAST_OUTPUT_REGSITER to output q1
set_instance_assignment -name FAST_OUTPUT_REGISTER ON -to q1
For more information about the slew fast input and output register features in the device, refer to the specific device handbook and the Intel® Quartus® Prime Help.
