Lesson 2: Creating Parts

This walk-through demonstrates several ways you can create and add parts to a Capture library. After you complete this topic, you will be able to:

  • Copy library parts and paste them into a new design library
  • Rename and edit a library part
  • Create a new part and add it to your design library

To follow along, continue with the design from the last topic or use the provided design files. If the design files were not downloaded in the beginning of the Capture Walk-Through, the design files for this lesson can be found under the Materials tab.

Open in New Window

Creating Parts from an Existing Library

Step 1: Select File > Open > Library from the menu.

Selecting the Capsym Library

Naming a New Part in OrCAD Capture

Step 13: Enter the following information:

  • Name: USB-MicroB
  • Part Reference Prefix: X
  • PCB Footprint: USB-MicroB

Note: Use TAB on the keyboard to quickly go to the next field.

Step 14: Click OK. The Part Editor tab opens.

Step 15: Click the boundary to display vertices.

Resizing a Part Boundary Box

Step 16: Click and drag the lower-right vertex to resize the boundary box to seven-by-seven units.

Step 17: Select Place > Rectangle from the menu.

Drawing a Rectangular Part

Step 18: Click to start drawing the rectangle and click again to finish. Right-click and select End Mode.

Step 19: Select Place > Pin from the menu.

Defining Pin Properties for Parts

Step 20: Define the pin properties as follows and click OK to place.

  • Name: GND
  • Number: GND
  • Shape: Short
  • Type: Input

Step 21: Click a location on the part boundary to place the pin.

Step 22: Press Shift-G on the keyboard to re-open the Place Pin window.

Step 23: Enter the pin values and place the pins using the properties below:

MT1MT1Zero LengthBi-Directional
MT2MT2Zero LengthBi-Directional
MT3MT3Zero LengthBi-Directional
MT4MT4Zero LengthBi-Directional
P_1P_1Zero LengthBi-Directional
P_2P_2Zero LengthBi-Directional

Note: When the pin ends in a number the next pin placed will be sequential. You can continue to click and place MT1 to MT4 and P_1 to P_2 without editing properties between pins.

Step 24: Right-click and select End Mode when finished.

Disabling Pin Name Visibility

Step 25: In the property sheet, de-select the Pin Name Visible checkbox.

Step 26: Select the <Value> text. Click and drag to move the text to a new location.
