Problems solved by technology

Although the patent involves the wiring structure, it does not involve the wiring problem of equal capacitance
The disadvantage of this patent is that it increases the length of the network cable and increases the resistance to affect the transmission of signals.
Further, this patent increases the volume and area of ​​the circuit board, which is not conducive to integrated circuit design

Abstract

The invention relates to an equal-capacitance wiring method. The equal-capacitance wiring method is characterized by at least including the steps of recognizing geometrical parameters of an area where wiring is to be conducted, segmenting the area where wiring is to be conducted into geometrical subsegments on the basis of the geometrical parameters, wherein the geometrical subsegments have serials with unique serial numbers; generating initial wiring according to an equal-width mode, and detecting and secondarily cutting geometrical subsegments not conforming to standard conditions; regulating geometrical characteristics and / or positions of the corresponding geometrical subsegments and / or cables in an adaptive mode on the basis of the comparison results of calculated capacitance values of at least one geometrical subsegment and / or each cable and a preset capacitance value. On the premise that the minimum cable width and the minimum interval required by the process requirements are met, the capacitance values of the distributed cables can be as small as possible and approximately equal, brightness of display pixels, corresponding to all the cables, on a liquid crystal panel can be the same, the display performance of the panel is improved, and the integration performance is further improved.

Description

technical field [0001] The invention relates to the field of electronic design automation, in particular to an equal-capacitance wiring method and device. Background technique [0002] With the continuous development of electronic technology, the wiring requirements for electronic design automation software for integrated circuits have been increased. The current mainstream wiring method is to first use automatic wiring and then fine-tune manual wiring. Automatic wiring has the characteristics of fast speed and high accuracy. Manual wiring adjusts the local unreasonable design of automatic wiring. Improve wiring efficiency and reduce the huge workload brought by a large number of integrated circuit components. [0003] According to different application requirements, different wiring schemes need to be adopted. At present, the commonly used wiring schemes include equal resistance wiring, fixed value resistance wiring, etc. Among them, the wiring requirements for equal resis...
