designing JTAG on a board for EP3C5E144C7N (cyclone III)

I am having trouble finding the pinout for the EP3C5E144C7N so I can try and build a board with a JTAG header. Does anyone know the proper pinout and connections to design a JTAG header on a EP3C5E144C7N ?

    OK, I will use at least 4 layer, and thanks for the JTAG advice !

    Do I need to add power to every VCC pin and ground every ground pin ? The tqfp PIC microchips (what I learned on ) were pretty lax , you just had to ground one ground pin and put power on one power pin wtih one decoupler, how is it with Cyclone III ?

    Thanks !

    you will need to connect all pins as directed in the schematic review worksheet and pin out files
