Example Embodiment

[0049] The present invention will be further described in detail below with reference to the drawings and specific embodiments of the specification.

[0050] In the field of software program testing, "Assertion" is a commonly used program testing method. To ensure the accuracy of the algorithm, chip designers often include comments in the program so that when scheduling or improving the algorithm, the chip designer can understand the operation of the algorithm more clearly, without having to simulate or synthesize the algorithm. Another technique used by programmers and chip designers to ensure the accuracy of the algorithm is to insert an assertion function in the program itself. Although some programming and hardware description languages ​​(HDL) include assertion functions in their libraries, there are still other more specialized assertion programs that can be run as part of a simulation program (computer, synthesizer, etc.) in order to be more concise and easier The asserti...

Abstract

The invention discloses a device and method for printed circuit board detection based on a schematic diagram assertion. The device comprises a testing device, a control unit and a debugging mainframe, wherein the testing device comprises a finger test unit and an image colleting unit. The finger test unit comprises a finger test element and an electromechanical moving module. The finger test element is driven by the electromechanical moving module to move, so that a contact tip of the finger test element is in continuous contact with a designated location of a circuit board entity. The control unit is used for controlling the motion of the contact tip through the electromechanical moving module according to the distance between the contact tip and a test point on the circuit board entity. The debugging mainframe is used for sending to the control unit a control command of moving the contact tip and is used for reading data results, making a comparison between the data results and the assertion and displaying the results. The method is based on the detection device. The detection device has the advantages of being simple in structure, simple and convenient to operate and high in automation degree.

Description

technical field [0001] The invention mainly relates to the detection field of printed circuit boards, in particular to a printed circuit board detection device and detection method based on principle diagram assertion. Background technique [0002] PCB board (Printed Circuit Board, printed circuit board) is one of the important components of the electronics industry.
