把原理图和PCB复制元件和封装到库及一些技巧(以抄OK6410及底座封装为例).doc

此文档收集于网络，如有侵权，请联系网站删除把原理图和PCB复制元件和封装到库的一些技巧（以抄OK6410的底座封装为例）今天 在飞凌官网下载了OK6410的原理图和PCB，如果想做一块Mini的底板。如何能最快地利用上飞凌原来画好的板，是我想解决的问题。1、首先，把飞凌官方的底板座复制下来，见下图：2、切换到PCB库，粘贴（注意，要在编辑区粘贴，不要在PCBLIBRARY那里粘贴，如果在那里粘贴的话会分开成5个封装的。）效果见下图：3、现在放大你会发现，那四个底座引脚的名称都是从1到80，这样元件库跟封装是对应不起来的。所以可以想个方法把那四个座的数字前分别加上ABCD。一个一个地改，这不是我风格，呵呵！探索开始了。还是直接贴结果吧，过程现在不重要，哈。在/display/ADOH/PCB+Inspector+Panel#PCBInspectorPanel-brosba2发现有一段是这样写的：Formula TabThis tab provides for more advanced modification, allowing you to apply a specific expression to the selected string objects. The expression can include any built-in arithmetic operators and functions that apply to strings (found in Pascal). Once again, if you wish to use the current value for the attribute as part of the expression, you will need to make reference to this original value, either by using the full name of the attribute, or by using the exclamation character (the supported substitute for the name of the attribute currently being modified). When using attribute names, if any names contain spaces, these must be replaced by the underscore character. So, for example, use of theComponent Commentfield within a formula should be entered as Component_Comment.Consider for example three selected memory components specified in a design, with designators U1, U3 and U5. You might want to extend the designators of these components by including some indication of their role. Using the addition operator, you could write an expression to add to the existing string value of theNameattribute. This would take the existing (original) string value and concatenate it with a specified new string, as illustrated below:Name + _MEMor, in shortened form:! + _MEMNote that the spaces are optional. When you pressENTERthe designators of the components will be updated to U1_MEM, U3_MEM and U5_MEM respectively.To illustrate the use of string-based functions consider the Copy function, which can be used to take a portion of an original string and place it within an expression to create a new string. Take again the Comms Port example (seeBatch Replacement of String-based Attributes), where strings of the form CommPortx_8 need to be changed to IOPortx_32. In this case you could select the four free string objects, access theSmart Editdialog for theStringattribute and write the following expression on theFormulatab:IO + Copy(String,5,6) + 32or, in shortened form:IO + Copy(!,5,6) + 32这里就不翻译了，直接上如何操作：用鼠标选中一个底座的引脚，打开PCBLIB Inspector点击Name 右边 的三点，打开Smart Edit 如图那样填写，确定后再放大那底座你会发现，那底座所有的引脚前都加上A了。用同样的方法给另外的底座分别加上BCD。4、下面再看一下怎么创建一个原理图库与之相对应：打开飞凌的原理图，把那个元件复制一下，如下图：转到原理图库，在SCH Library 那里粘贴，注意，在编辑区域是粘贴不了的。由于人们复制的封装有四个底座，所以建四个部分，见下图：然后选中选
