Problems solved by technology

[0003] For areas with high component density on the circuit board, since there are wiring constraint areas around each component to avoid signal interference or short circuit, the signal routing needs to bypass multiple wiring constraint areas and maintain a certain line between different signal lines. Therefore, the wiring personnel can only splice the line segments in small sections by trial and error (try and error), which makes the wiring speed extremely slow
And irregular wiring is not conducive to signal transmission, but also produces a lot of electrical and signal impedance, which affects the electrical connection quality and electrical function of the circuit board

Embodiment

[0015] Fig. 1 is a schematic diagram of the basic structure of the arc winding system of the present invention. The arc-shaped winding system of the present invention performs wiring on a high-density area of ​​a circuit board containing multiple components, and the components are connection pads (Pads), pins (Pins) or through holes (Vias) and the like. The arc winding system is integrated in an existing wiring system (software), such as Allegro, and can also be plugged into the wiring system for its calling. When the wiring system wires the circuit board and enters a high-density area containing multiple components, the arc-shaped winding system of the present invention can be called. Three selection points A, B, and C on both sides of the line direction, wherein the selection point A is located on one side of the line direction, and the selection points B and C are sequentially distributed on the other side along the line direction. The arc-shaped winding system draws an ar...

Abstract

This circuit composition aid system composites in the hi density area of circuit board including many components. A selection module selects 3 selection points along both sides of the circuit line. One point is on one side and the other two on the other side. The reading module (RM) fetches the related info and the wire-going info of the selected points. According to the info from RM, the enactment module (EM) enacts the center position and the radius of the arc and enacts the start / end points of the arc-type winding. A winding drawing module draws the arc-type winding pattern according to the center position, the radium, the start point, and the end point from EM and wire-going info from RM. This invention raises the wire composition efficiency and the electric connecting quality of circuit boards.

Description

technical field [0001] The invention relates to an arc-shaped winding system and method, in particular to an arc-shaped winding system and method for wiring a circuit board component density area. Background technique [0002] With the development of high-density integrated circuits, the demand for wiring using electronic design automation (Electronic Design Automation: EDA) software has increased. Regarding the circuit layout (Layout), the more common wiring method at present is the method of combining automatic wiring and manual wiring. Compared with manual wiring, automatic wiring has the characteristics of fast completion speed and high accuracy, and can respond more quickly to the requirements of the market for product design. However, in areas with high component density, manual wiring is required to achieve the effect of optimized wiring. [0003] For areas with high component density on the circuit board, since there are wiring constraint areas around each component...
