[0150] The second embodiment provided by the present invention includes:

[0151] Step 301 , expressing product devices and connection relationships between product devices based on two-dimensional table units.

[0152] In the schematic design tool, place the required product devices, represent the network connected to the pins of the product devices as the row and column numbers in the two-dimensional table, and then write the scripts supported by the tool in a specific table tool or other second It is a secondary development method to extract the effective information in the table and replace the information in the schematic design file.

[0153] Step 302, converting the connection relationship between the product components expressed in the two-dimensional table into an XML text file described in the extensible markup language XML.

[0154] Step 303, drawing a schematic design file based on the XML text file.

Abstract

The present invention relates to a method for drawing schematic diagram design file and its system. It is characterized by that said method includes the following steps: firstly, connection relationship generation module can utilize two-dimensional table unit to formulate product devices and connection relationship between product devices; then information conversion module can convert the connection relationship between product devices which is formulated by using described two-dimensional table into XML text file which can be formulated by using extendible mark language XML; finally, schematic diagram drawing tool can utilize described XML text file to draw the schematic diagram design file.

Description

technical field [0001] The invention relates to the PCB design technology in the field of communication, in particular to the drawing of a schematic design file. Background technique [0002] Usually, in the hardware design process of an electronic product, the design document is written first, then the schematic design document is drawn, and then the netlist is generated to drive the PCB (Printed Circuit Board, printed circuit board) design. However, in the process of complex electronic product design, with the expansion of the system scale, the increase of complexity, and the needs of other aspects such as enterprise product data management, it is generally not possible to directly draw the schematic design file, but in the schematic design Before the document is drawn, the product design is described layer by layer through the detailed hardware design document, and then the detailed hardware design document is carefully reviewed, and then the drawing of the schematic desi...
