Bringing HPS bus to GPIO pins

Question

Hello,
            We would like to use an external logic analyzer with our Terasic DE-1 boards in our undergraduate teaching lab. We would like to bring the HPS bus to the GPIO pins, but I'm not sure how to do that directly, or if we should connect the bus to I/O buffers. Any suggestions would be very appreciated.

Hi,
If you're talking about the FPGA's GPIO, then you can but you need to setup and bring up the HPS. You may refer below for guidance:

Let me know if more help needed.
