Problems solved by technology

[0015] However, according to the flow of the above-mentioned traditional method, even if the above automatic testing method is adopted, the results cannot be checked and compared automatically
It is still necessary to manually switch between the schematic diagram, PCB and circuit board entity many times, which reduces the debugging efficiency, increases the error probability, and prolongs the development and debugging time

Embodiment Construction

[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[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 more clearly understand the operation of the algorithm without having to simulate or synthesize the algorithm. Another technique used by programmers and chip designers to ensure the accuracy of algorithms is to insert assertion functions within the program itself. While some programming and hardware description languages ​​(HDLs) include assertion functions in their libraries, there are other more specialized assertion routines that can be run as part of a simulation program (computer, synthesizer, etc.) for more concise and easier to perform assertions within a progr...

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.
