Accessing HPS Pins

Hello, I know I can route HPS pins to the FPGA side but is it possible to do the opposite, route FPGA side logic to HPS part pins? Thank you

When you use the EMAC HPS I/O pins as loaner I/O don't expect them to have to have many features. As you can see from the output there is no altddio atom in the HPS I/O. Loaner I/O do not have double data rate logic, delay chains, registers, etc... in them. Loaner I/O are intended to be use for low speed connectivity since the I/O is limited in functionality and the delay between two adjacent loaner I/O is much more than what you are accustom to with the regular FPGA I/O.
