Problems solved by technology

[0004] As far as the current working procedure is concerned, layout personnel use computer equipment to create geometry files and symbol files based on relevant part specification information. However, the types of part specification information are various and complex. file and symbol file, errors may occur in the created geometry file or symbol file due to human error
For example, wrong pin names or pin numbers are entered, and errors are often discovered and modified during component layout operations or circuit layout operations, and sometimes even errors are not found, which will affect the design of printed circuit boards quality and efficiency

Embodiment Construction

[0018] Please refer to figure 1 , is a flowchart of the method steps of the present invention. Such as figure 1 As shown, the pin information proofreading method of the present invention is applied to computer-executable circuit diagram layout software to check whether the pin information of the same circuit element in a symbol file and a geometry file is consistent, and its pin information proofreading method Contains the following steps:

[0019] First, a symbol file is read to obtain first pin information of a circuit element (step 100). Since the previously created symbol files can generally be stored in the hard disk or CD-ROM of the computer equipment, please refer to figure 2 As shown, it is a schematic diagram of the circuit element in the symbol file of the present invention, and the symbol file has included information such as the figure of the circuit element 200, each pin name (G1, G2) and each pin number (1-15), Therefore, by executing the program for reading...

Abstract

The invention relates to a pin information proof-reading method which is applied to a computer executable line distribution software for checking whether the pin information of the same circuit elements in a symbol file and a geometry file is consistent; the method comprises the following steps: read the symbol file to obtain first pin information of the circuit elements; search geometry recorded information corresponding to the circuit elements from a catalogue file according to the name of the symbol file; obtain second pin information of the circuit elements from the geometry file according to the geometry recorded information; compare whether the first pin information and the second pin information are consistent; search an information comparison table when the first pin information and the second pin information are not consistent, so as to obtain reminding information and the reminding information and the comparison error information are displayed on a computer screen.

Description

technical field [0001] The invention relates to an information checking method, in particular to a pin information checking method. Background technique [0002] In the design process of printed circuit boards, the previous layout design is one of the very important tasks. Among them, the operation of using computer to draw the printed circuit board is mainly divided into two parts, one is the front component placement (placement) operation, and the other is the back circuit layout operation. [0003] Circuit components in symbol files and geometry files are usually used in component layout operations. The symbol files contain the graphics of circuit components, the names of each pin, and the number of each pin, etc. information, and the geometry file not only contains information such as the graphics of the circuit components, the name of each pin, and the number of each pin, but also contains more detailed information, such as the spacing value of each pin of the circuit ...
