Abstract
A testing circuit for testing proper connections between pins and corresponding circuits within an integrated circuit includes a pin selection module. The pin selection module includes a plurality of input pins, an output pin, and a control pin. The pin selection module selectively connects one of the input pins to the output pin based upon a control signal from the control pin. A voltage-dividing module includes an input end to receive a test voltage, an output end connected with the output pin of the pin selection module, and a voltage-dividing element connected between the input end and the output end. A determination module receives an output voltage from the output end, and determines whether the voltage of the output end falls into one of several predetermined voltage ranges, and outputs a result accordingly.
