Hi snehal_p,


The HPS_GPI pins are different from other HPS peripheral pins or GPIOs. The HPS_GPI (referenced as HLGPI in Cyclone V TRM - chapter 22) are HPS dedicated pins and doesn't appear as ports on generated HDL entity. You can't even configure their usage via QSYS. These pins has fixed location and function and hence no assignment is needed.


Thanks.

Regards,

Aik Eu
