第3讲-Cadence分裂元件的制作方法(Lesson 3 – manufacturing method of cadence splitting element)

笔记3-Cadence分裂元件的制作方法

1.Homogeneous和heterogeneous的区别;

2.创建homogeneous类型元件;

3.创建heterogeneous类型元件。

把元件分成多个部分制作。

1.右击*.olb/New Part/打开New Part Properties窗口。在其中Parts per Pkg:设定分成几个部分,Package Type:选择类型。这里用NE5532为例来讲解两种类型的元件制作方法。注意参照Datasheet。

2.先演示Homogeneous类型的制作步骤。Name:NE5532_HOMO;Parts per Pkg:2;Package Type:Homogeneous.

3.开始画元件符号,画运放的边框,三角形,这里用文本工具添加同相输入和反相输入,放置时用Option/Perference/Grid Display/Pointer snap to grid.来取消网格对齐,放置后还原。-改成+,双击即可修改。然后再调整虚线框。添加管脚。管脚属性参照Datasheet。调整,保存。元件的第一部分完成。

4.Ctrl+N,进入元件的下一部分编辑。同样设置管脚属性,第二部分也需要添加两个电源管脚。

如果一个芯片放在一张图上画,管脚的名称和序号不能相同,元件分开画,允许。至此,Homogeneous介绍完毕,像这种功能简单的芯片,可以隐藏管脚名,Option/Part proference/Pin Names Visible/false。Ctrl+B返回A部分。保存。

另一种Hetergeneous:

步骤同上,建立元件时,类型,名称不同即可。画运放符号部分也同上。最大的区别就是第二部分不需要再添加正负电源管脚。

View/Package可全显示;View/Part分开显示。Ctrl+B/N切换。

Homogeneous用起来简单,Hetergeneous相对复杂些。

Manufacturing method of note 3-cadence splitting element

1.Homogeneous和heterogeneous的区别;

2. Create homegenetic type components;

3. Create heterogeneous type components.

The components are divided into several parts.

1. Right click *. OLB / new part / to open the new part properties window. Among them, parts per PKG: the setting is divided into several parts, and package type: select the type. Here, take ne5532 as an example to explain the manufacturing methods of two types of components. Please refer to datasheet.

2.先演示Homogeneous类型的制作步骤。Name:NE5532_HOMO;Parts per Pkg:2;Package Type:Homogeneous.

3. Start to draw component symbols, draw the frame and triangle of the operational amplifier. Here, use the text tool to add in-phase input and inverse input. When placing, use option / preference / grid display / pointer snap to grid. To cancel the grid alignment and restore after placing- Change to +. Double click to modify. Then adjust the dotted box. Add pins. Pin properties refer to datasheet. Adjust and save. The first part of the component is completed.

4. Ctrl + n to enter the next part of component editing. Similarly, to set pin properties, two power pins need to be added in the second part.

If a chip is drawn on a drawing, the pin name and serial number cannot be the same, and the components are drawn separately, which is allowed. So far, the introduction of homogeneous has been completed. For chips with simple functions, you can hide the pin name, option / part reference / pin names visible / false. CTRL + B returns part A. preservation.

另一种Hetergeneous:

The steps are the same as above. When creating components, you can use different types and names. The drawing of operational amplifier symbols is also the same as above. The biggest difference is that the second part does not need to add positive and negative power pins.

View / package can be fully displayed; View / part is displayed separately. CTRL + B / N switch.

Homogeneous is simple to use, while heterogeneous is relatively complex.
