Hot FPGA!

My FPGA gets really hot after configuration. I've checked my power pins, and they are all connected to the correct supplies which are all within tolerance. Any other suggestions?

Yeah, you're lucky if your unused pins are set to "Output, Driving Ground" and all that happens is that your chip gets hot. I've seen some designs where that destroys components. In general, I think it's safer to stick with "As Inputs, Tri-stated".
