TW576987B - Method for simultaneously drawing plural traces - Google Patents

Abstract

There is provided a method for simultaneously drawing plural traces, which is primarily applied in PCB layout to allow the layout engineer to simultaneously draw the traces for coupling the components such as chips to the connection pads. Each trace is vertical with the connection pad. Accordingly, it is able to overcome the trouble in sequentially drawing the trace in the conventional skill, and also avoid that the trace violates the rule of being vertical with the connection pad, thereby greatly reducing the error rate of layout.

【發明之應用領域】 .本發明係關於—種電腦繪製印刷電路板（pcb，printed C0irCUl1： b〇ard)線路佈局（Layout)圖的顯示方法，特別 是一種用以同時拉出多條走線之方法。 【發明背景】[Application Field of the Invention] The present invention relates to a method for displaying a printed circuit board (pcb, printed C0irCUl1: b〇ard) circuit layout (Layout) diagram, particularly a method for simultaneously drawing out a plurality of traces Method. [Background of the Invention]

合在印刷電路板的設計過程中，先期的電腦繪圖設計是 相當重要的工作之一，其中運用電腦繪製印刷電路板的作 業主要又刀成兩部分，一是前面的定位處理（piacement) 作業 另 個則疋後面的線路佈局（L a y 〇 u t )作業；當電子 工程師對於一個印刷電路板的定位處理工程完成之後，即 將该印刷電路板後續的線路佈局作業，交由線路佈局工程 師（Lay out eng i neer )進行後續的線路佈局工程。In the design of printed circuit boards, early computer graphics design is one of the most important tasks. Among them, the use of computers to draw printed circuit boards is mainly divided into two parts. The following is the layout of the circuit (Lay ut); when the electronics engineer's positioning process for a printed circuit board is completed, the subsequent layout of the printed circuit board is handed over to the layout engineer (Lay out eng) i neer) for subsequent line layout engineering.

但當線路佈局工程師開始著手線路佈局作業時，經常 性的必須由元件（c 0 m p 〇 n e n t，如晶片）接腳（p i n )所耦接之 連接塾（p a d ) ’拉出一條又一條的走·線（t r a c e )，同時必須 注意到每一條拉出之走線必須與矩形之連接墊邊緣垂直的 規則，不過’工程師光是注意整個圖層的走線是否有足夠 的空間擺設就已費盡心思，因此由元件拉出之走線常常會 不垂直於其連接墊，導致還要再重新修線的麻煩，無形中 降低了作業速度與效率。 【發明之目的及概述】 本發明的目的在於提供一種同時拉出多條走線之方 法，.藉由本方法的操作，可達到使線路佈局工程師提高作 業效率之目的。But when the circuit layout engineer starts the circuit layout operation, it is often necessary to connect the pads (pad) that are coupled by the pin (c 0 mp 〇nent, such as a chip). · Traces. At the same time, you must pay attention to the rule that each of the drawn lines must be perpendicular to the edge of the rectangular connection pad. Therefore, the wiring drawn by the component is often not perpendicular to its connection pad, which leads to the trouble of having to repair the wiring again, which virtually reduces the operating speed and efficiency. [Objective and Summary of the Invention] The object of the present invention is to provide a method for simultaneously pulling out a plurality of traces. Through the operation of this method, the purpose of enabling a circuit layout engineer to improve the operation efficiency can be achieved.

Description of the invention (4) wire (step 3 3 0), of course, each trace is perpendicular to the connection pad; finally, the pulled-out trace is set to the protection mode (step 3 4 0). Different from the previous embodiment, this embodiment provides a judgment of whether component selection is correct or not. In addition, in order to avoid the user from mistakenly selecting the edited routing during the subsequent operation, the routing will be pulled out. Set to protected mode. Both of the above are helpful for the correctness of the circuit layout operation and can improve the operation efficiency by reducing the error rate. Secondly, in the above step 340, the operation of pulling the wiring is achieved through the detailed flowchart shown in "Figure 4." When the user presses the function key of the user interface, the pin type, geometry name, and package mode in the geometric database are first obtained by the reference name of the component (step 4 1 0), and then the corresponding reference name is obtained by the component. The relationship between the pin number and the pin name in the position file of this pin type (step 4 2 0), and then use the above two kinds of data to combine the directions of the pins that can be pulled out (step 4 3 0), and finally It is based on four parameters such as the pin number and the center position of the pin, the extension direction, and the corresponding cable name. The cable is pulled out by the connection pads of each pin according to the direction and the preset length (step 4 40). Although the present invention is disclosed in the foregoing preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and retouching without departing from the spirit and scope of the present invention. The patent protection scope of the present invention shall be determined by the scope of the patent application scope attached to this specification.
