error of PCIE PERST_N whe running fitter!

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 

 

 

how to solve this problem ?

Change the pins I/O standard to one compatible with the VCCIO level on that bank, or move the pin to another bank with a compatible VCCIO level.

PERST_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.

so if there is other solution for this problem?

If this is a board you've designed then you are out of luck - you should have test compiled your pin assignments before getting the board made. 

 

If it is a dev kit then whoever designed the dev kit did a terrible job. 

 

You can't put pins that require 1.5V VCCIO on the same bank as pins that require 2.5V/3V VCCIO, and there is no work around as far as I'm aware.
