It looks like you're trying to connect your own logic to dedicated HPS pins on the FPGA. These signals are intended for the HPS to host an I2C bus. So, it's not as straightforward as simply constraining your design in the way, I suspect, you have.

You can connect your own logic to these HPS signals. Refer to an 706: mapping hps ip peripheral signals to the fpga interface (www.altera.co.uk/literature/an/an706.pdf) for details of what you can do.

Cheers,
