图11-49 多路滤波器PCB图

(6)把图11-51的元件标号统一旋转成水平方向的。打开 “PCB Filter”面板,在“Find items matching these criteria:”栏, 输入“IsDesignator”语句,按“Apply”按钮,选中PCB板上所有 元件的标号。

AltiumDesigner原理图和PCB多通道设计方法

原理图和 PCB 多通道设计方法目录1.问题描述 (3)2.设计过程 (3)2.1原理图设计 (3)2.2 PCB设计 (4)3.结论与经验 (6)【关键词】:多通道设计1.问题描述设计原理图和 PCB 的过程中,经常会遇到过多幅一模一样的电路,特别是驱动电路。
原理图显得繁复,可读性差;而特别是在设计 PCB,不得不重复布局,重复布线,不仅枯燥乏味而且也容易出错、电路不美观;由于PCB布局一致性差,导致硬件测试时每个部分都要重复测试,耗时又繁琐。
下面就介绍一种专门针对这类电路的设计方法,多通道电路设计,大大提高工作效率,以上问题都可以得到很好的解决。
这里有点类似我们写程序的时候,把一段经常用的代码,封装为一个函数,减少重复劳动增加可读性。
2.设计过程2.1原理图设计首先需要理解何谓多通道设计。
简单的说,多通道设计就是把重复电路的原理图当成一个原件,在另一张原理图里面重复使用。
下面介绍一个例子,在范例里面更便于理解这个概念。
一个有 4 路IGBT驱动电路。
如下图是一路IGBT驱动电路:如果按照常规设计,在原理图里这个相同的电路不得不 copy 4 次,这样电路图必然繁琐,而且原理图和PCB 多通道设计方法3 / 5耗费时间。
下面用多通道设计试试。
把一路IGBT 驱动电路设计好以后保存,然后在同一个工程下面新建一个空原理图。
打开新原理图,在里面做文章。
首先选择 Design/Create Sheet Symbol From Sheet or HDL,激活该命出现对话框,选择需要的驱动电路图,点击ok,出现如下图:把绿色方框图按照需要的次数复制出来,该次我们需要复制三次。
如下图这个绿色块就是驱动电路的替代品了(也可以把他当中一个原件,或者一个函数入口)。
四个驱动电路需要四个绿色块,取名A,B,C,D;分别对应四个驱动电路,将每个驱动电路的net 名称对应好,添加相应的换页符,GND/POWER可以不写。
Altium_Designer6.9软件操作实用笔记 自己也修改

Altium Designer 6.91、一个项目里可以有多张分立的原理图。
2、一项目里多张分立的原理图不能单独分开分别导入不同的PCB,导入一个PCB时同一项目所有原理图一定是个集体,并一定会一起同时导入这个PCB,也就是一个PCB一定包含这个项目所有原理图。
但可以画多张PCB。
3、当原理图张数或电路改变时,重新导入PCB后,会使PCB更新至和已有原理图一致,当在PCB改变了位号时更新原理图,在原理图重新编译下会在原理图已有位号旁显示更改后的位号。
但不改变已有位号。
4、多张分立的原理图导入到PCB电源是连接的。
5、多张分立的原理图如需信号连接,需建立层次原理图,否则导入到PCB板互不连接。
6、默认设置—TOOL---Preferences---defauts7、按住CTRL+SHIFT滚动鼠标滑轮切换层(在PCB操作界面)8、选中按住SHIFT再拖动元件为复制功能(在原理图的操作下,可以使用,这种操作复制出来的元器件的标号自动增加)★★★★★9、选中一个元件,CTRL+R连续放置,CTRL+D相当于CTRL+C和CTRL+V 复制再粘贴,或对着元件按E再选(区别于上面的操作,复制出来的元器件的标号和母体是一样的)10、选中,按住CTRL拖动元件为DRAG功能,即链接导线会跟随延长,与MOVE功能移动不一样,按M键出现DRAG和MOVE,DRAG可以方便两个芯片引脚对应连接,再拖动,避免一根一根线连(原理图操作界面,实用功能)★★★★★11、EDIT-----BREAK WIRE 断线(原理图界面)12、PLACE---DIRECTIVE(directive)---NO ERC 不进行ERC电气规则检查(原理图界面红色叉叉具有同样的功能 Place No ERC)13、PLACE---DIRECTIVE---compile mask 编译屏蔽罩14、原理图编译:Project---compile document sheet (编译功能是什么作用?)15、原理图标号排序:Tools---Annotate Schematics (未尝试)16、原理图右下角的模板添加,Design—template—set templatefile name打开自带的模板路径找到Templates文件夹进入打开即可,更改模板内容Design—Document options—parameters 更改Value即可(何功能?)17、CTRL+F 查找(原理图界面,可用)18、CTRL+H 查找并替换(原理图接界面,Text to Find选择需要修改的原件,Replace With要改成的原件编号)19、层次原理图从顶层到子层绘制,先绘制顶层,再单击一个原理图模块symbol右键选择sheet symbol actions---create sheet from symbol 创建子原理图。
Altium Designer 学习笔记(总结)

●∙在PCB板界面(默认是二维画面)时使用【Shift+M】键可以快速打开滤镜(即放大镜),再次使用此组合键可以退出滤镜功能,该快捷组合键同样适用于三维PCB界面。
●∙在PCB界面中,按数字键3,打开PCB板的三维界面;在三维界面时,按数字键2,则又切换到二维界面。
●∙在PCB的三维界面时,按住Shift键不松开,同时按下鼠标右键,则可以旋转PCB板。
●∙通常说的低速板一般是指最高频率小于40~50MHz的板子。
●∙画PCB板时尽量用45度的折线代替90度的折线。
●∙当新建了一个PCB项目并且又添加了两个原理图文件,在保存到指定文件夹时,默认是先保存原理图表单1、接着保存原理图表单2,最后保存的是PCB项目。
即保存的顺序是由内向外的。
在PCB项目被保存后,其实Design Workspace(工作区间)也被保存了。
●∙已打开的文件隐藏后,可以在Window下拉框里对应项中打开。
●∙打开原理图编辑器属性设置对话框(即文件选项)有四种方式,1、在Design->Document Options中打开;2、按快捷键【D+O】;3、在原理图界面边缘上或其外部双击同样能快速打开对话框;4、在原理图编辑界面中点击鼠标右键,在弹出的对话框中选择Options->Document Options。
●∙按住Ctrl键的同时按下鼠标右键,然后上下滑动鼠标也可以实现缩放功能。
●∙按Shift+Space键可以切换4种连线模式。
要注意输入法的选择,否则可能无法切换。
●∙PCB Rule和Parameter Set的属性设置都是在Place ->Directives里面打开(前者选择PCB Layout,后者选择Parameter Set),当选择Add as Rule时,添加的属性的Name都是Rule,当选择添加时,属性的Name随设置的不同而异。
●∙当点击Parameter Set后,再按F1键,则会快速打开Knowledge Center。

Altium Designer 14原理图与PCB设计教程 第五章 总线、层次和多通道原理图设计

5.1 具有多部件元器件符号和总线结构原理图绘制
5.1.1 多部件元器件符号概念与放置
1.多部件元器件符号概念 多部件元器件就是同一个元件中存在很多相同 的单元电路,例如常见的数字芯片74HC14 (六反向施密特触发器)就是一块芯片中含有 6个相同的反向施密特触发器单元,如图5-1-1 所示。
图5-1-1 74HC14的元件符号
多部件元器件符号中各单元的元 器件名称相同、图形相同、只是 引脚号不同,在标号U1的后面以 A、B、C、D分别表示第一、第 二等单元,标号U1表示在元器件 库中同属于一个元器件符号,如 图5-1-2所示。
图5-1-2 74HC14的六个独立的部件单元
2.多部件元器件符号的放置
图5-1-12 Port Properties对话框
放置端口后的原理图如图5-1-15所 示。 再次从图5-1-15生成多部件元器件, 此时生成的多部件元器件中自动含 有原理图中加入的端口,如图5-116所示。
图5-1-16 带有端口的多部件元器件
图5-1-15 放置端口后的电机驱动原理图
5.1.3 总线概念与绘制
图 5-2-21
5.3 多通道原理图设计
多通道设计就是把重复电路的原理图当成一个原件,在另一张原理图里面重 复使用。完成了自下而上层次原理图设计。 如图5-3-1所示,电路的功能是π型衰减器,输入输出阻抗均为50Ω,衰减 为5dB。该电路可以作为信号源与放大器之间的匹配电路使用。
图5-3-1 π型衰减器电路原理图
根据自上而下的原则,整个电路设计分为两个层级。顶层电路由晶体振荡器 模块、预推模块、功放模块和天线匹配模块四部分组成。第二层级分别是各个模 块具体的电路实现。

使用AD画PCB也好几年了,自认为水平一般,也没画过多高级复杂的板子。
虽然早知道AD可以实现多层图纸设计,也知道可以多通道设计。
但由于之前自己画的板子都不算复杂。
偶尔可能会遇到有多通道(两三个),但出于比较懒的原因,从来没有尝试过这个功能,宁愿自己把原理图复制复制再复制,然后对元器件重新编号。
画板子时就随便拉几条参考线,把元件大致摆的差不多,然后一块一块又一块的重复布局布线。
但最近遇到了一个较为复杂的板子,一开始还想使用笨办法,但发现相当折磨。
无奈只得研究一下这个多通道设计。
先整一个简单的例子尝试是否好用,一开始各种报错,各种不顺,折腾半天后终于算是顺利搞定。
在此把自己摸索的过程以及遇到的问题分享给大家。
个人感觉,多通道设计还是有很多好处的。
比如:减少重复性工作(无论是设计原理图还是PCB,工作量都大大降低)。
降低人为犯一些低级的错误,比如某一通道个别器件可能会弄错,原理图整体显得简洁美观等等。
第一步:先是建立一个PCB工程,然后新建一个原理图(一个子模块的原理图),由于是学习摸索,图省事,我画了一个挺简单的图。
第二步:
再建立一个新的原理图,然后点击菜单Design》Create symbol from sheet or HDL,弹出如下图所示的对话框,选择上一步建立的子模块电路。
第三步:生成如下图所示的模块
第四步:进行多通道设计,这里我们使用Repeat功能。
Repeat(SheetSymbolDesignator,FirstInstance,LastInstance)
其中,SheetSymbolDesignator是图表符的本名,FirstInstance和LastInstance一起定义了通道数;注意FirstInstance参数必须等于或大于1,如下图所示表示是4个通道。
修改模块名称和网络名称。
比如我需要设计4通道,那么,名称修改为:
Repeat(MODE,1,4)
其中ON和OFF网络,每个模块是独立的,即应该是NO1,NO2,NO3,NO4。
那么相对独立的网络名也需要使用Repeat重命名,电源地与同用的全局网络就不需要修改了。
修改完成后的多通道模块如下图所示:
第五步:连接这些网络,连接完成后的顶层原理图如下图所示:
这里强调几点:
1、总线必需要有网络标号(比如ON[1..4]这个),不同的网络不能重复。
2、模块的总网络必需有标号(比如ON,OFF)
3、模块中网络不共用的,必需要Repeat重新命名
第六步:点击菜单Project>>Compile Document检查原理图是否有错误,若没有错误点击菜
单Design》Updata PCB DocumentXXX,将原理图导入到PCB文件中。
第七步:对其中一个ROOM进行布局布线
第八步:将已经布好的ROOM模块应用到其它未完成的ROOM中。
点击Design>>Rooms>>Copy Room Formats出现十字光标,先点击已经布线完成的ROOM,再点击要布线的ROOM,弹出如下对话框
红框中,根据需要选择,比如四通道布局一样的话就全选,如果特殊点:1,3一样,2,4一样,那就只选择需要一样布局的ROOM。
点击OK后,即自动完全4个模块的布局,如下图所示:
第九步:完成非重复部分的布局与布线,如下图所示(由于只是摸索功能,所以布局布线什
么的都是随便连上的,不过本人水平也比这随便布的好不了多少)
注意:在布局布线未完成前,一定不要删除ROOM,否则再调整起来会很麻烦。
图中的元器件编号,被自动按模块分成了A,B,C,D四模块。
如果感觉不舒服,可以重新对其编号。
点击:Tools>>Re-Annotate弹出如下对话框,选择适当的编号规则即自动编号。
编号完成后如下图所示,接下来还需要将PCB中的编号与原理图进行同步,点击Design>>Updata Schematics
点击Execute Changes后,即对原理图中的编号进行了同步。
