Shared Bus Memory Interface with Cyclone 3

[shahulakthar]

Hi,
I need to interface SRAM and Flash memory with cyclone 3 fpga.In that i am planning to use shared address bus and data bus for SRAM and FLASH Memory to commmunicate with fpga. Is it Possible? IF it possible what are all the things i have to taken care.Thanks in advance.

Do you want to use the Flash to program the FPGA as well or not? If not, then it is pretty straight forward, just make sure the Chip select and OE signals of the Flash and SRAM are not activated at the same time and your logic does not violate the setup and hold time for those signals.
