I was working with a Zynq Xilinx FPGA running at 3.3V. For some reason, I did not realized that my power supply was shorted and I stopped getting the output. I tried checking by taping my finger on the FPGA and it nearly burnt my finger. I have no idea why it was too hot. I immediately turned the main power supply off. I am still figuring out why it was shorted but is the FPGA ok? I did no see any smoke coming out from it. Once I figured out the short with the power, I will plug the power back in. Also, how long do we have (if something is heating up) to turn the power off and the chip is still safe?
