Our free PCB file viewer offers a quick and intuitive way to locate and navigate to components and nets anywhere in your design. Improved EAGLE Support With improved support for Autodesk EAGLE file formats, you can experience them exactly as you do in the desktop tool. Open the product folder, OrCAD/Allegro PCB Editor. This file is included in the zip folder you downloaded from Ultra Librarian. Note: You must already have OrCAD or Allegro software installed and running on the computer that created the batch file or you need to modify the path referenced in the batch file.
A PCB Gerber file for each section of your electronic circuit design is what you need if you want to create a PCB. In order to ensure delivery time and reliability of end products, PCB design engineers should learn how to generate PCB Gerber files on their own. PCB Gerber files generally contains design data of signal layer, soldermask layer and silkscreen layer.
NEVER change the OrCAD and Allegro PCB Editor’s Global environment file or copy it to the pcbenv directory to use as the local environment file. The correct procedure for customizing your paths and adding aliases required at the start up of the OrCAD and Allegro PCB Editor is to add this information to your local env file in the pcbenv.
Nowadays, there are three versions of Gerber formats available:
• Gerber X2 - the newest Gerber format with stackup data and attributes contained.
• RS-274-X - an expanded version of Gerber format and it has been widely applied.
• RS-274-D - the oldest version of Gerber format which is being gradually replaced by RS-274-X
Different PCB design software feature different operation steps of PCB Gerber files generation. In the following part of this article, We will show you how to generate PCB Gerber file from Cadence Allegro in details.
Open your PCB layout in Cadence Allegro:
1. First, manually add artwork layers, and then click Manufacture>>Artwork.
2.Click General parameters, setting as shown below:
3.Then click Film Control,add artwork layers, add a board outline by right-clicking on the TOP folder and picking Add Manual.
4. Determine a film name, OUTLINE for example and click OK button.
5. In the Subclass Selection window, expand BOARD GEOMETRY and tick OUTLINE. Then, click OK button
6. Back to Artwork Control Form window, tick OUTLINE if it has stayed in the area of Available films.
7. Use the same method to add other layers, Assembly layer is similar to the picture below
All the signal layers are set similar to the picture below:
Drill layer is set similar to the picture below:

Silkscreen layers are set similar to the picture below:
Paste mask layers are set similar to the picture below:

Then setting and output the drilling file
1. Add the drilling table
Open the Drill layer through the Views list of the Visibility option on the right side of the screen, and select both the PIN and Via options in the Visibility option, as shown below:
Then click Manufacture>>NC>>Drill Legend, as shown below:
The drilling table parameters are setting as shown below:
Kicad Open Pcb File
Click the OK button, a drilling table appears, placed in the appropriate place on the board.
2.Output the drilling file
The parameters are setting as shown below:
Output drilling files, as shown below, it is best to click the dirll button to generate .Dril files which means drilling files
With these steps finished, you need to re-confirm whether each parameter is set correctly, if there is no problem,press Select all button with all the layers output. Then, PCB Gerber files will be generated when Create Artwork button is clicked.

The instructions that follow explain how to import files you downloaded from Ultra Librarian into OrCAD/Allegro PCB Editor v15.2.

Ensure that the version you select to download matches the software version that you have installed. Before you begin to import, extract the zipped download on the computer that has OrCAD/Allegro PCB Editor installed. This enables the batch script to run.
To import your new library parts into OrCAD/Allegro PCB Editor:
1. Using your Windows Explorer, navigate to the downloaded AllegroV15.2.bat file that is included in your download folder.
This batch file contains instructions for your computer. You must have OrCAD or Allegro PCB Editor installed in the expected location in order to run the batch file. If OrCAD/Allegro PCB Editor is installed in an unexpected location, edit the lines of your batch file that reference the OrCAD or Allegro tools.
2.Double-click the AllegroV15.2.bat file to run the batch file.
The batch process creates additional files needed to support the import. First the padstack tool is loaded and then the part building software runs.
3.Move the files created by the batch run to an appropriate directory structure where the parts are available for use in your board.
To open your new library file after successful import:
1.Open OrCAD/Allegro PCB Editor and create a board file.
2.Select the Place > Manually menu options.
The Placement window opens.
3.Browse through the list of symbols on the left side of the window.

4.If an item is missing from the selection list, click the Advanced Settings tab and verify both the Database and Library check boxes are selected.

When you return to the Placement List tab and browse for the missing symbols, the files should now be included in the list. However, if the files are still missing, the actual file may be saved in a different directory. If that is the case, move the files to the same directory as your other PCB Editor library files.
5.To select a symbol in the list, place a check mark in the box to indicate your selection.
6.Place the symbol on your board with a left mouse click.
