Why do I get the following error when the PERST pin of the Stratix® V Hard IP for PCI Express I/O Standard is set to 1.5V in the Quartus® II software v14.1?

Description

Error (169029): Pin pin_perst is incompatible with I/O bank 3B.

Pin uses I/O standard 2.5 V, which has a VCCIO requirement incompatible with that bank's VCCIO setting or its other pins that use VCCIO 1.5V.

Due to a problem in the Quartus® II software v14.1, I/O standard checking is too restrictive.

Resolution

To work around this problem in the Quartus II software v14.1.

1. Remove the location assignment of pin_perst.
2. Add a quartus.ini file in your project directory with: dft_skip_oct_vccn_check = on

No plan to fix.
