Method for detecting pin connectivity of integrated chip

Abstract

The invention relates to the technical field of integrated circuits, in particular to a method for detecting pin connectivity of an integrated chip. The method comprises the following steps: S1, providing an integrated chip which provides a universal input/output interface; S2, providing terminal equipment providing an output pin connected with the universal input/output interface correspondingly;and S3, switching the high-low level state of the universal input/output interface to detect the level state of the output pin so as to determine a line connection relationship between the integratedchip and the terminal equipment. The method has the following beneficial effects: the pin connectivity of the peripheral circuit of the integrated chip is detected; the operation difficulty of hardware is reduced; observation becomes convenient; the test result is accurate; and the debugging progress is further improved.

Confirmed Connectivity Affects Debug Progress of Integrated Chips

[0003] At present, the measures taken by the industry are to detect the impedance value of the integrated chip terminal and the terminal equipment through the impedance range of the multimeter. It is necessary to know the two connected positions of the integrated chip terminal and the terminal equipment. The operation is cumbersome and requires a lot of energy and time. And the detection accuracy is not high
