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?

    Good suggestions from all. I'd like to add, if you have a way of measuring power supplied to the core or bank power supplies, check to see which is responsible for supplying all the current. If it’s the core, then it’s not I/O contention problem (i.e. IO set as GND driving against VCC on the board). If you can turn off clocks, then it could be asynchronous circuit free running as someone indicted. If it’s the I/O, along with the suggestions already provided in previous posts, check buses to make sure no two chips are contending also.

    What was the actual problem.?

    My fpga board is heated up now and I am scared if the board is spoilt. My program was running which i could visualize by the blinking LEDs. So it means that the Fpga is not spoilt right?
