8 years agoPERST_N is a designated pin for PCIE hard ip, and its voltage is required as 3.3v. but this bank's VCCIO is set to 1.5v for QDR interface.
when I change the pin I/O standard to 1.5v , same error occurs and additionally one warning reports : Warning (15772): Pin PERST_N cannot have I/O standard assignment 1.5 V. The pin is a PCIe reset pin connected to the HIP and is therefore powered by VCCPGM. The Fitter is ignoring this assignment. Error (169029): Pin PERST_N 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. Extra Info (169121): Device 5SGXMA3H2F35I3 so if there is other solution for this problem?
