Cyclone III dev board (flash and psram at the same time)

Hi everybody,

I would like to know if it is possible to have access in the same design at the flash memory and the psram. Indeed, in the FPGA and on the board, these memories have the same pinout and it is boring.

I am using the psram on my FPGA design, and i would like to use the flash memory to store my nios C program. Is this possible, without affecting the access performance of my design ?

Thank you for your answers.

    The flash and the sram have different chip select pins, so if you connect both peripherals to the same avalon tristate bridge in SOPC builder and ask it to share the address and data buses it should work.
