3.3V FPGA with 5V PCI..?

["Dinesh Kumar" <eyesol@rediffmail.com>]

Hi all,

We are using an FPGA based local to PCI bridge whose I/O is in 3.3V but with input tolerance of 5V. The PCI side of the bridge is supposed to work with a standard 5V PCI add-on card. PCI local specs. 2.2  DC specification (page 117) for 5V signaling indicates that input high – min is 2.0 V. 
Is this design OK ? Is there any other parameter to be considered as far as 3.3V FPGA hosting 5V add-on card is considered ?

Thanks in advance
