“Beep” when testing VCC and GND with the multimeter. Ask Question Asked 4 then it is probably the continuity tester charging up the power supply filter capacitors. However, if it is continuous, then this is not necessarily indicative of a short circuit. I have several FPGA boards (large Virtex 6) with Vccint supplies of 1.0 V, and and the Vccint supply rail on these read as shorted to
