Cyclone III health status

Altera_Forum · ‎08-25-2009

Hi!

While measuring the voltage on an output pin of my Cyclone III starter board, I slipped off and produced a short curcuit to a 12V output pin. Now the FPGA is getting really hot (burning my fingers) shortly after power-up. A little demo-application is working correctly and I figured out, that some pins are stuck at 1 now. But my main-design doesn't seem to work, even though it does in post-synthesis simulation.

Is there any way to check the health status of a Cyclone III FPGA?

Thanks!

Your finger did a good job of telling you the status of the chip ... The cost of a new board is less then all the trouble you could be facing trying to use one that has been half burned up. Next time use a sharp pin on the test lead so you can't touch 2 pins at the same time.
