Circuit-board laying-out method

Abstract

The invention is a circuit board layout method, comprising the steps of: providing a circuit diagram; establishing and storing electronic components and their attribute parameters in a database; drawing the attribute parameters the circuit diagram indicates from the database and inserting the attribute parameters of electronic components in the circuit diagram in the indication positions of the circuit diagram; when converting a circuit diagram into a circuit layout diagram, a designer obtains sizes, pin positions and connection relations of electronic components and other graphic data at the time of circuit layout design according to the attribute parameters of electronic components in the circuit diagram. And the invention benefits circuit layout design, raising layout efficiency and reducing artificial mistakes.

Description

Technical field [0001] The present invention relates to a circuit board layout method, in particular to a method of embedding graphic attribute parameters in an electronic component of a circuit diagram to meet the requirements of circuit layout. Background technique [0002] For electronic devices with excellent performance, in addition to selecting high-quality electronic components and reasonable circuits, the layout of printed circuit board components and the impedance of circuit connections are also factors that affect the quality of the electronic device; for circuits with the same components and parameters Because of different component layout designs and circuit connections, there will be different impedance values, and the impedance magnitude affects signal transmission and control stability. Therefore, how to reduce the impedance generated by the circuit layout and eliminate the noise interference caused by improper wiring, which is conducive to the installation, debugg...

Problems solved by technology

[0005] The above steps all use professional computer software as an aid, such as design circuit software (ConceptHDL) and circuit wiring software (Allegro), but if you look at the process of the overall layout of the circuit board, since the design and layout of electronic components rely on electronic design The engineer's layout experience is manually configured; if a large number of electronic components are manually configured on the circuit board, it will be quite time-consuming and laborious, not in line with economic benefits, and has the following disadvantages: (1) The electronic components are manually configured. To configure, you must be very careful. In the process of configuring a large number of electronic components, the electronic design engineer will inevitably have negligence and omissions; if the passive components or related components are placed in the wrong position or placed too far away, it will cause debugging time Longer, more serious will lead to failure to debug and repair, making the design cycle longer

(2) After the electronic design engineer completes part of the circuit layout, if the specification of the electronic components used in the circuit board is changed and the configuration position of the components must be changed, for the electronic design engineer, it is necessary to redesign, so it will cost a lot of money. More time and effort to make revisions
