how to power FPGA up?

[mostafa_m]

I have an FPGA and I want to configure it. I have JTAG cable which I can used to program it. But I want to know how to power it. I have control on all of it pins and I know it VCC and gnd pins. I want to know which VCC pins to cconnect. I connect only 1 VCC and VJtag pins only. is that right or I must connect all the Vcc and Gnd pins.

Thanks

You would need to connect all the VCC and ground pins. There are multiple ones for a reason. Usually they are connected to different sections of the circuits to construct VREFs and other grounding systems.

I sure hope you don't just have an FPGA sitting on their desk and are soldering wires to the balls. (If you are...then the part is probably already damaged due to ESD).

You also better adhere to any specific power up sequencing of the supply rails, especially ones that dictate any voltage differential between voltage rails. If you violate those you'll usually either damage the part or reduce its lifespan significantly.
