Circuit connection calibration system and method

Abstract

The present invention relates to a circuit connection checking system and a method thereof. The system is loaded to a printed circuit board circuit design system which is at least provided with a drawing module, a wiring module and a circuit pattern base and at least comprises a database of attribute data of a template element, an actual element and a wiring element; through a template circuit schematic diagram, an actual circuit schematic diagram drawn by the drawing module according to the template circuit schematic diagram and a circuit wiring schematic diagram generated by the wiring module according to the actual circuit schematic diagram, the attribute data of the template element, the actual element and the wiring element are analyzed and stored in the database; a first class element attribute information and a second class element attribute information of the template element, the actual element and the wiring element are extracted from the database and compared to output a result; according to the result, the difference of the first class element attribute information and the second class element attribute information of the template element, the actual element and the wiring element is indicated in the actual circuit schematic diagram and / or the circuit wiring schematic diagram. The invention improves the wiring accuracy in the process of distributing circuit patterns and reduces amendment opportunity after the circuit patterns are distributed.

Description

technical field [0001] The present invention relates to a circuit connection verification system and method, more specifically, a circuit connection verification system and method mounted on a design system used in a data processing device for making circuit patterns of printed circuit boards. Background technique [0002] With the high density of integrated circuits and the rapid development of electronic technology, the current printed circuit board (PCB) layout (Layout) is usually completed by Electronic Design Automation (EDA) software. The more commonly used design systems include Protel, Allegro, Mentor, etc. [0003] Usually, the circuit board design of these design systems includes steps such as drawing circuit schematic diagrams, converting the drawn circuit schematic diagrams into wiring schematic diagrams, and performing actual wiring according to the wiring schematic diagrams. Omission or loss of connection lines often occurs during the image conversion process....

AI Technical Summary

Problems solved by technology

When the drawing operation is completed, when the wiring schematic diagram is generated, because repeated inspection takes a lot of time, it is likely that the drawn circuit schematic diagram will not be checked again, and these pins will be regarded as floating pins that do not need to be connected. (unconnected pin) to be processed, which will cause the missing unconnected pin to be subsequently generated in the wiring schematic diagram

However, if the error is discovered when the wiring work is carried out to a late schedule, since the current integrated circuit wiring density is very high, there is generally no free space for wiring at the center of the chip pins, such as adding signal lines, etc. Waiting for modification may lead to the removal of many or even all the lines that have been laid out and start again, wasting a lot of precious time, causing delays in the completion of the entire circuit pattern layout, and low work efficiency.
