  1. 1. Build Your Own PCB with EAGLE II – Drawing a Schematic <ul><li>Source: CadSoft </li></ul>
  2. 2. Introduction <ul><li>Purpose </li></ul><ul><ul><li>To explain how to draw a schematic using EAGLE Schematic Editor. </li></ul></ul><ul><li>Outline </li></ul><ul><ul><li>EAGLE Schematic Editor User Interface </li></ul></ul><ul><ul><li>Key steps for drawing a schematic </li></ul></ul><ul><ul><li>Schematic output </li></ul></ul><ul><ul><li>Component design </li></ul></ul><ul><li>Content </li></ul><ul><ul><li>14 pages </li></ul></ul>
  3. 3. Schematic Editor User Interface Title Bar Toolbar Menu Bar Parameter toolbar Command Line Command Toolbar Working Area Coordinate Display Status Bar
  4. 4. Creating a New Schematic <ul><li>If your right click on the project and select “New -> Schematic”, it will bring up the Schematics Editor Window; or </li></ul><ul><li>You can select “File -> New -> Schematic to start the Schematics Editor. </li></ul>
  5. 5. Adding a Frame <ul><li>Click “Add” button ( ) in command toolbar or type “add” in command line to open “ADD” dialog. </li></ul><ul><li>Select a suitable frame from the frames-library (frames.lbr) . </li></ul><ul><li>After add a frame, click the stop icon or press ESC to Terminate the ADD command. </li></ul>ADD Command : Add elements into a drawing. Library List Search Box Symbol Preview Package Preview Description Area
  6. 6. Adding Components <ul><li>If you have place a component with ADD, and then want to return to the ADD dialog in order to choose a new component, press the ESC key or click the ADD icon again. </li></ul>Definition of attributes for devices Cope devices Delete devices Swap equivalent gates on a schematic Call a specific symbol from a device Mirror devices Move devices Display and change the name of a device Define a package variant for a device Replace a device Rotate a device Highlight a device Separate text variables and attributes from devices Display and change values Define the possible technology parts of a device name
  7. 7. Wiring the Schematic <ul><li>Use the NET command ( ), not WIRE to draw net connections. </li></ul><ul><li>Nets with the same name are affiliated with each other. </li></ul>NET Command : Draw nets on a schematic. Nets with same name
  8. 8. Drawing a Bus <ul><li>A bus has to be drawn with the BUS command ( ). </li></ul><ul><li>A bus does not create any electrical connections. </li></ul>BUS Command : Draw buses in a schematic. Bus Name List of Net name
  9. 9. Electrical Rule Check (ERC) <ul><li>The ERC command ( ) is used to test schematics for electrical errors. </li></ul><ul><li>The results are warnings and error messages listed in the ERC window. </li></ul><ul><li>The ERC can only discover possible error sources. </li></ul>ERC Command : Electrical rule check. A line points to the corresponding location in a schematic for the selected errors or warnings.
  10. 10. Schematic Output <ul><li>For documentation purposes, the drawing can be output using the PRINT command. </li></ul><ul><li>The PRINT command allows generating PDF files. </li></ul><ul><li>The EXPORT command is used to provide you with ASCII text files which can be used to transfer data from EAGLE to other programs. </li></ul><ul><ul><li>Netlist: generates a netlist for the loaded schematic. </li></ul></ul><ul><ul><li>Partlist: generates a component list for schematics. </li></ul></ul><ul><ul><li>Pinlist: generates a list with pins, containing the pin directions and the names of the nets connected to the pins. </li></ul></ul><ul><ul><li>Image: exports an image file (*.bmp, *.png, *.pbm, *.tif, etc.) </li></ul></ul>
  11. 11. Generating Bill of Material <ul><li>Select “File -> Run…”, a dialog pops up for selecting the User Language Programs. </li></ul>Select “bom.ulp” to generate the BOM
