Embodiment Construction

[0057] The preferred implementation examples of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] A specific implementation example of the present invention is illustrated by taking a schematic circuit diagram including CPU, memory DDR (Double Data Rate, internal memory), FLASH (flash memory), FPGA, Ethernet device, and RJ45 socket as an example.

[0059] Step 1: see attached Figure 5 , for the circuit devices required by the design, use third-party tools or EDA software embedded tools or functions to build a device information library 130 or a device schematic library 120 , and this function or tool is called library tool 100 . as attached figure 1 , attached figure 2 , attached image 3 The example is the device information library edited by third-party tools, taking CPU devices and RJ45 sockets as examples, see the attached figure 2 And attached image 3 . Step 1 establishes the device informatio...

Abstract

The invention relates to the field of circuit schematic diagram design, in particular to a method for automatically drawing a schematic diagram. Aiming at a circuit device, a detailed device library or device information library is set up, a circuit schematic diagram scheme is made according to a certain specification, the device or circuit schematic diagram scheme is guided into a schematic diagram drawing tool, an interconnection relation and a signal name are automatically or manually assigned, and then the automatic drawing tool is utilized for recognizing the information for automatic wiring and real-time inspection between device pins. The schematic diagram can also be manually modified, various statistical information reports can be output after completion, the information can be utilized for automatic inspection of the schematic diagram, relevant errors are inspected, or an optimizing scheme is given, correction continues to be carried out, and repeated iteration is carried out till schematic diagram design is completed.

Description

technical field [0001] The invention relates to the field of circuit schematic diagram design, in particular to a method for automatically drawing schematic diagrams. Background technique [0002] Circuit schematic design is the basic ability of PCB (Printed Circuit Board, printed circuit board) circuit design engineers. Usually, circuit design engineers use some kind of EDA (Electronic Design Automation, electronic design automation) tools, such as Protel, Mentor, Candence and other tools, to design and draw circuit schematic diagrams. Designers generally use EDA tools to build a schematic library and PCB library of circuit devices, and then call the devices in the library, and manually connect to complete the circuit schematic design and drawing. Then import the designed schematic diagram into the PCB tool for PCB layout and wiring design. Various current EDA tools have very rich functions and friendly interfaces. Circuit designers can use these EDA tools to complete the...
