EAGLE Version 6 and 7 – Introduction to the Control Panel

Overview of the EAGLE Control Panel

The Control Panel is the first interface you encounter when launching EAGLE. It provides access to all the essential tools and settings required for PCB design. The main components of the Control Panel include:

1. Library Management
2. Design Rule Management
3. Project Management
4. User Language Programs (ULPs)
5. Options and Preferences

Library Management

EAGLE libraries contain a wide range of components, devices, and symbols used in PCB design. The Control Panel allows users to easily manage these libraries, including adding, removing, and updating them as needed.

Adding Libraries

To add a new library to your EAGLE installation, follow these steps:

1. In the Control Panel, click on the “Libraries” tab.
2. Right-click in the empty space and select “Add Library.”
3. Navigate to the location of the library file (*.lbr) and click “Open.”

The library will now appear in the list of available libraries.

Removing Libraries

To remove a library from your EAGLE installation:

1. In the “Libraries” tab, right-click on the library you wish to remove.
2. Select “Remove Library.”

Note that removing a library does not delete the library file from your computer; it only removes the reference to the library within EAGLE.

Updating Libraries

EAGLE libraries are regularly updated to include new components and fix any issues. To update a library:

1. Download the latest version of the library file (*.lbr) from a reliable source.
2. In the “Libraries” tab, right-click on the library you wish to update.
3. Select “Replace Library” and navigate to the location of the new library file.
4. Click “Open” to replace the old library with the updated version.

Design Rule Management

Design rules are a set of constraints and guidelines that ensure your PCB design meets manufacturing and reliability standards. The Control Panel provides a centralized location for managing and editing these design rules.

Creating a New Design Rule

To create a new design rule:

1. In the Control Panel, click on the “Design Rules” tab.
2. Right-click in the empty space and select “New.”
3. Enter a name for your new design rule and click “OK.”
4. Double-click on the newly created design rule to open the Design Rule Editor.
5. Adjust the various parameters, such as clearance, trace width, and via size, to meet your specific requirements.
6. Click “OK” to save the changes.

Editing an Existing Design Rule

To edit an existing design rule:

1. In the “Design Rules” tab, double-click on the design rule you wish to edit.
2. Make the necessary changes in the Design Rule Editor.
3. Click “OK” to save the changes.

Applying a Design Rule to a Project

To apply a design rule to a project:

1. Open the project in the EAGLE Schematic or Board Editor.
2. Click on the “Tools” menu and select “DRC…”
3. In the DRC (Design Rule Check) dialog box, select the desired design rule from the “Design Rules” dropdown menu.
4. Click “Check” to apply the selected design rule to your project.

Project Management

The Control Panel is also used for managing EAGLE projects, which consist of schematic and board files. Users can create new projects, open existing ones, and archive projects for storage or sharing.

Creating a New Project

To create a new project:

1. In the Control Panel, click on the “Projects” tab.
2. Right-click in the empty space and select “New Project.”
3. Enter a name for your project and click “OK.”
4. Right-click on the newly created project and select “New Schematic” to start designing your circuit.

Opening an Existing Project

To open an existing project:

1. In the “Projects” tab, navigate to the folder containing your project.
2. Double-click on the project name to open it.

Alternatively, you can use the “Open Project” button in the Control Panel toolbar to browse for and open a project.

Archiving a Project

To archive a project for storage or sharing:

1. In the “Projects” tab, right-click on the project you wish to archive.
2. Select “Archive Project.”
3. Choose a location to save the archived project file (*.zip) and click “Save.”

To unarchive a project, simply right-click in the “Projects” tab and select “Unarchive Project.” Browse for the archived project file and click “Open.”

User Language Programs (ULPs)

User Language Programs (ULPs) are scripts written in EAGLE’s built-in scripting language that automate tasks and extend the software’s functionality. The Control Panel provides access to the ULP Manager, where users can run, edit, and manage these scripts.

Running a ULP

To run a ULP:

1. In the Control Panel, click on the “User Language Programs” tab.
2. Navigate to the folder containing the desired ULP.
3. Double-click on the ULP file to run it.

Some ULPs may require additional user input or configuration before running.

Editing a ULP

To edit a ULP:

1. In the “User Language Programs” tab, right-click on the ULP file you wish to edit.
2. Select “Edit” to open the file in the EAGLE Text Editor.
3. Make the necessary changes to the script.
4. Save the file and close the Text Editor.

Managing ULPs

The ULP Manager allows users to organize their scripts into folders and share them with others. To create a new folder:

1. In the “User Language Programs” tab, right-click in the empty space.
2. Select “New Folder.”
3. Enter a name for the folder and click “OK.”

To move a ULP into a folder, simply drag and drop the file into the desired folder.
