Why would IO pins be tied to VCC or GND with 0 Ohm resistor on FPGA Dev Board?

Trying to find out the voltage threshold for input of a GPIO pin in an FPGA development board

will find entries like: set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to i_serIn set_instance_assignment -name CURRENT_STRENGTH_NEW 8MA -to o_LED[0] and so forth to let you know what that FPGA
