In-System Programmable Solution for Board With Both Virtex5 and CycloneII FPGAs

[Altera_Forum]

Hi, 

 I'm designing a board that will have a Xilinx Virtex5 and an Altera CycloneII FPGA on there, and I was wondering if there exists a solution where I can use just one Flash device for both FPGAs. Thanks for any insight.

You can add a PLD on you board with will program's the fpga's. For example first the CycloneII and then the Virtex5. 

 Or you can use one of the FPGA to configure the other one. Example the Virtex5 is configured form the flash first. The Virtex5 reads some other part of the flash chip and configures the CycloneII.
