Read documentation from the EAGLE and the community. Simple example of how to get started with a EAGLE design. by CadSoftSupport. start the tutorial take 5 minutes to go through the Cadsoft EAGLE Guided tour, to get an EAGLE can also be used to design multi-layer and single-sided PCBs.

    Tutorial for Creating Device Models in CAE Tool CadSoft EAGLE Abstract: Tutorial for handling the EAGLE1 library to create customized device models used. EAGLE. EASILY APPLICABLE GRAPHICAL LAYOUT EDITOR. Manual This software and documentation are copyrighted by CadSoft Computer, doing. PCB introduction. • CadSoft EAGLE introduction. • Schematic design. • Board layout and routing. • CAM processor export. • DFM. • Fabrication. • Assembly. 2.

    This preview shows page 1 - 8 out of 28 pages. Table of Contents 1. Introduction 1. Schematic Capture 2. PCB Layout 3. Project Submission 4. Although it is capable of producing professional designs, EAGLE has a large hobbyist following because of its freeware version. It will cover basic tools and navigation in the schematic editor, creating traces in PCB layout, and generating the gerber files used in fabrication. Figure 1. There should be a green dot next to the name indicating that it is active. Figure 2. Eagle Schematic Editor On the left is the toolbar, and the large white space is where you design the schematic.

    It is possible to export data from your schematic or layout into any format. Importing data is possible as well. Provided you have a good description of the data format you could write such a program by yourself in order to import data into EAGLE.

    ULPs can be used to modify your project and automate certain tasks. You are allowed to specify several folders, if you like. For example you may prefer to have the default libraries available on a server and your personal ones located in your private folders.

    EAGLE creates a number of backup files each time you save your project. There is a maximum of 9 possible backups. They are named with the file extension. They get the extensions. Right above the design space is the command bar where you can type in commands to access different tools. Above the command bar are the action buttons open, save, zoom etc.

    The toolbar contains many useful tools, and this tutorial will cover most of them. There are many parts that you can access, enough that it might actually be difficult to find the part that you are looking for. To aid you, you can use the search bar circled in red to type in what you are looking for.

    The results will vary with part implementation, source, and symbols, so browse through and find the part that suits your need best. The Eagle search engine can be difficult to use at times, so it may take a few different searches to find a particular part.

    To do that, use the Net Tool , not the Wire Tool this does not make an electronic connection.

    To keep the schematic neat, we recommend using only right angled nets electrical connections. One is where you have two crossing wires that are connected and the other is where you have a T-intersection.

    Eagle will probably place a green dot where a junction occurs, but if not you must use the Junction Tool to place a green dot at these junctions otherwise Eagle will interpret these intersecting or crossing wires as not connected. To delete any connections or junctions, simply use the Delete Tool. If this is the case then you must call the Invoke Tool on the IC.

    A window similar to picture A should come up. In the end, Vdd should be connected to the positive supply voltage, and Vss should be connected to ground. Eagle provides an ERC tool that will check any electrical errors such as missing junction dots, floating pins that require connections, or unpowered components. Instead, we have to layout our current schematic on a PCB Board, so click the Board tool corner to move to the board layout screen. First off, like the schematic editor, the board editor is laid out on a coordinate grid current coordinates shown on the top left and has a similar toolbox except for a few additional tools which we will be using.

    Second, the white outline in the black portion of the interface is outline of your board. Third, for reference, the dotted crosshair in the bottom left corner of the white outline is the origin 0 0. Our first step will be to resize the board. Using the Move Tool , grab the top left corner of the board and drag it down to 2.

    Proceed similarly with the two other corners. Next we will deal with our components and jumbled mess of yellow wires. To help us, the components are connected by airwires the yellow wires that correspond to electrical connections in the schematic.

    You should ideally place the components on your board such that you have as few yellow lines overlapping as possible. This is easier said than done especially with complicated circuits, so here s a possible layout you can try to save time: By no means is this the best or the most efficient solution, but it works and can be easily routed. Note that some components are blue because they have been put on the bottom layer using the Mirror Tool.

    This is also a good time to click the Ratsnest Tool to recalculate the air wires and try to clean up the mess a bit. This tool reroutes airwires such that ground and power wires have the shortest distances and least wires. Click the tool, and with the Top layer selected, create a 10 11 polygon along the border of the board.

    It will appear as dotted line. This tells Eagle to connect all ground wires to this plane. Repeat this process for bottom layer. Now when you click the Ratsnest Tool , Eagle will flood the ground planes like so: 3.

    Making all these traces manually is tedious, but luckily, Eagle comes bundled with a really useful feature called the Autorouter which will route most of your traces for you automatically. Most of your traces will be routed and you will notice some airwires still remain.

    Most, if not all, of the remaining traces will be ground connections that got disconnected from the ground plane in the autorouting process.

    This occurs because the ground planes get split up into islands due to interweaving traces.

    To complete the routing, use the Route Tool to drag a trace out form an airwire endpoint out to an area where a via can be placed. A via is a copper-lined hole that makes a connection between layers along its conductive lining. Use the Via to make connections between layers.

    Instead, you must use the Ripup Tool. This tool deletes a segment of a trace or a via.

    You may encounter clearance and dimension errors where traces or vias are too close to each other or to the edge of the board. This tool will also tell you of any overlapping traces you may have accidentally made. Like with the ERC tool, please use this tool to double check your board before sending it out to be fabricated.

    You might be wondering, aren t the white labels I see on my screen going to be on my board? Sadly, no. Those letters are just identifiers in Eagle s interface.

    In order for the final board to have the labels on it, you must put the labels on a silkscreen. To do that, first smash the labels you want to show up on the board.

    This will make the label has a crosshair in one of its corners that you can use to select and manipulate the label, so select the crosshairs with your move tool to move the text to the location of your choice. When you are close to finishing up, make sure everything is nice and neat by making sure all labels you don t want aren t there and none of the labels overlap with pads.

    In the end, you should end up with a picture like: Now, let s do some magic. Now, go back to your schematic and press the ULP button.

    If you did all that, a silkscreen layer will be made with a beautiful yellow color. Now if you have extra room on your board, you can put your logo on the silkscreen, as shown above. To do this, you first need to g enerate a logo following some rules outlined below 1.

    The next and pictures must be one color, black Black helps to reduce problem later on, but remember your picture will be pure white on the PCB 2.
