How can I interface between FPGA (spartan 3E) and aurduino ?
 

That should depend on compatible ports available on the 3E and aurduino board. It communication protocol can also depend on the volume and nature of data to be shared.
Serial communication should be available on both boards.

I think if you are using one of the older digilent boards you might need those pmod connectors to connect between the Arduino and FPGA I'm not sure though maybe someone else can go into more detail.
 

Hi, It depends on how the data is going to be shared between arudino board & SPARTAN 3E FPGA. Here the Arudino board has predefined I/Os & Bus timing protocols. Where as in FPGA you can configure the GPIOs as per your requirement. Make sure that whether you want to interface Data bus (Uni/Bi-Directional) of Arudino to FPGA, or simple i/o port of Arudino to FPGA. After confirming that, refer the timing specs of Arudino i/o and FPGA, create the timing events based signal for handshake between two devices. hope you understand what i mean,..
