How can i Configuration the two types FPGA device family at once?

Hi, all

I have develop a system with 2 pcs CycloneIII FPGA, the one is EP3C10 and the other is EP3C25. The SRAM object file of them is different. In order to reduce the system board area, I want to store their config file(1.pof, 2.pof) into one piece EPCS device and finish the configure process at once after power on.

From CycloneIII handbook, I find the solution that config multi-device with the same density and package using multi-SRAM object file. I also find that It can config the multi-device with with the same density and package using the same SRAM object file. But I did not find the solution can apply in my system.

Is there the method can complete my idea? If it exists, Hope give me a guide. Thanks!
