Problems solved by technology

[0002] At present, the speed of high-speed signals on printed circuit boards (PCB, Printed Circuit Board) is getting faster and faster, such as PCIE, SATA, USB3.0, QPI, DDR3, etc. Reaching 8Gbit / s, while the power consumption of printed circuit boards is continuously required to be reduced, which brings more and more difficulties to the design of electromagnetic compatibility (EMC, Electro Magnetic Compatibility) of the motherboard, while the traditional method for printed circuit boards The means of testing the electromagnetic compatibility of electromagnetic compatibility often rely on the experience of engineers. This method is not only inefficient, error-prone, and difficult to batch operations

Embodiment Construction

[0028] see figure 1 , which schematically shows a flowchart of a method for detecting electromagnetic compatibility of a printed circuit board according to an embodiment of the present invention, the method includes the following steps:

[0029] Step 101, acquiring a layout of a printed circuit board. The layout of the printed circuit board can be a digital layout directly drawn by a layout drawing tool, such as a layout file with the suffix .brd generated by Cadence allegro layout design software, or it can be a photograph or scan of the printed circuit board via an image acquisition tool Generated digital layout.

[0030] Step 102, select an electromagnetic compatibility testing item from an electromagnetic compatibility testing item list, and the electromagnetic compatibility testing item is associated with at least one electromagnetic compatibility rule script. In one embodiment, a user interface is provided to the user, and a list including a plurality of electromagneti...

Abstract

An electromagnetic compatibility (EMC) testing system includes a layout information obtaining module, a script loading module, a script executing module, and a report generating module. The layout information obtaining module obtains layout information of a printed circuit board. The script loading module loads an EMC testing script which includes EMC rules. The script executing module executes the EMC testing script to determine whether the layout information of the printed circuit board complies with the EMC rules. The report generating module generates an EMC report describing whether the layout information of the printed circuit board complies with the EMC rules.

Description

technical field [0001] The invention relates to the field of printed circuit boards, in particular to a method and device for detecting the electromagnetic compatibility of printed circuit boards. Background technique [0002] At present, the speed of high-speed signals on printed circuit boards (PCB, Printed Circuit Board) is getting faster and faster, such as PCIE, SATA, USB3.0, QPI, DDR3, etc. Reaching 8Gbit / s, while the power consumption of printed circuit boards is continuously required to be reduced, which brings more and more difficulties to the design of electromagnetic compatibility (EMC, Electro Magnetic Compatibility) of the motherboard, while the traditional method for printed circuit boards The means of testing electromagnetic compatibility often rely on the experience of engineers. This method is not only inefficient, error-prone, but also difficult to batch operations. Contents of the invention [0003] In view of the above, it is necessary to provide a rel...
