Cadence Tutorial

Example : Schematic Capture (CMOS Inverter) Step 1 : Open a new schematic window Note : Before you begin with going through this example, be sure that you have the Library Manager open.

1. Click File on the menu banner in the Library Manager and hold the left mouse button until you choose New and then Cellview.

A small new window called "Create New File" appears.

2. There are four main fields in the Create New File window :

Library Name

You have to choose your working directory by clicking and holding the left mouse button on the Library field. Since our library name is "tutorial" in this example, we choose the corresponding label, "tutorial".

Cell Name

Enter the name of your cell for which you will draw the schematic. In our example, we will draw the schematic of an inverter, so we type "inverter" in the Cell Name field.

View Name

The View Name indicates the level of the design hierarchy. You can determine that you are going to draw either a symbol or a schematic or a layout in this field just by typing the corresponding view name. Since we will draw the schematic of an inverter, the correct view name choice is "schematic" for our example.

Tool

Here, you have to select the design editing tool that you will use to enter your design. The tool depends on the hierarchy level of your design. If you click and hold the left mouse button on the tool field, you will see the available tools. Only three of these tools will be used for all the examples.

Composer Schematic : Schematic editor Composer Symbol : Symbol editor Virtuoso Layout : Layout editor

Since we will draw a schematic, we choose "Composer Schematic". Choosing Composer Schematic automatically converts the View Name to schematic. Actually, the selected tool converts the View Name to the corresponding one.

3. Now, click on "OK" to close this window and open the new schematic editor window chosen in the "Create New File" window.
