How connect 2 FPGA ?

hi, I want to connect many IO between 2 Cyclone III located on two different cards. I have to make an impedance matching or can I connect them directly ? Best regards

With short, and equal length, wires and the transfer of the clock, and synchronous signals from one board to the other and recovery of the transmitter clock at the receiving side by means of a PLL 100 MHz is on the edge, but should be possible.
