    QEDA

    QEDA is a Node.js library aimed to simplify creating libraries of electronic components for using in EDA software. You can easily create both symbols for schematic and land patterns for PCB.

    Features

    • Downloading component definitions from global repository
    • Generating schematic symbols:
      • Single and multi part IC (dual-in-line, quad)
      • Connector
      • Capacitor, crystal, diode, FET, fuse, inductor, LED, pushbutton, resistor, switch, test point, transistor, TVS
      • Power supply, ground
      • GOST style alternative
    • Borrowing packages dimensions from standards:
      • Industrial (JEDEC, JEITA)
      • Manufacturer's (NXP)
    • Land pattern calculation according to IPC-7351 (tending to comply latest IPC-7351C):
      • Chip Array
      • Dual (CFP, DIP, SOIC, SOJ, SOL, SON, SOP)
      • Grid Array (BGA, CGA, LGA)
      • Mounting hole
      • Oscillator (corner concave, side concave, side flat)
      • Quad (CQFP, QFN, QFP)
      • Radial lead (Cylindrical)
      • SOT (SOT143, SOT223, SOT23, SOTFL)
      • Test point
      • TO (*PAK)
      • Two Pin (Aluminum Electrolytic Capacitor, Chip, Crystal, Molded body, MELF, SOD, SODFL)
      • Custom element
    • Generating libraries:
      • KiCad format
    • 3D models generation

    Installation

    QEDA module for using in scripts as well as command line interface:

    npm install -g qeda
    

    Examples

    First example will download component descriptions from library repository then save them to disk and add to library manager. Last string is to generate component library in KiCad format (schematic symbols for Eeschema as well as PCB footprints for PcbNew).

    CLI

    Run in terminal (note that component names are case insensitive but power and ground nets are not):

    qeda reset
    qeda add altera/5m1270zt144
    qeda add analog/ad9393
    qeda add st/l3gd20h
    qeda add ti/iso722
    qeda power +5VDC
    qeda power +3V3DC
    qeda ground GNDDC
    qeda ground signal/GNDS
    qeda ground earth/GNDE
    qeda ground chassis/GNDCH
    qeda generate mylib
    

    And find generated files in ./kicad directory.

    Read more about available commands.

    From script

    Example is written on CoffeeScript but one can use vanilla JavaScript.

    script.coffee:

    Qeda = require 'qeda'
     
    lib = new Qeda.Library
    lib.add 'Altera/5M1270ZT144' # Add Altera MAX V CPLD 
    lib.add 'Analog/AD9393' # Add Analog Devices HDMI interface 
    lib.add 'ST/L3GD20H' # Add STMicroelectronics gyroscope 
    lib.add 'TI/ISO722' # Add Texas Instruments digital isolator 
    lib.power '+5VDC' # Add power supply symbol 
    lib.power '+3V3DC' # Add another power supply symbol 
    lib.ground 'GNDDC' # Add ground symbol 
    lib.ground 'Signal/GNDS' # Add signal ground symbol 
    lib.ground 'Earth/GNDE' # Add earth ground symbol 
    lib.ground 'Chassis/GNDCH' # Add chassis ground symbol 
    lib.generate 'mylib'

    Run it:

    coffee script.coffee
    

    And find generated files in ./kicad directory.

    Custom component description

    Any electronic component is described using YAML-file located in ./library directory (or some subdirectory within). You can clone all available descriptions from https://github.com/qeda/library, add your ones, copy from any source. Then just point correspondent path as parameter for qeda add ... command or Qeda.Library.add method (without ./library/ prefix and .yaml suffix).

    library/dummy.yaml:

    name: Dummy
     
    pinout:
      DIN: 1
      ~DOUT: 2
      Vcc: 3
      GND: 4, 5
      NC: 6-8
     
    properties:
      power: Vcc
      ground: GND
      in: DIN
      out: ~DOUT
      nc: NC
      inverted: ~DOUT
     
    schematic:
      symbol: IC
      left: DIN, NC
      right: ~DOUT, NC
      top: Vcc
      bottom: GND
     
    housing:
      outline: JEDEC MS-012 AA

    Read more about component description.

    Then run in terminal:

    qeda reset
    qeda add dummy
    qeda generate dummy
    

    Or create custom.coffee:

    Qeda = require 'qeda'
     
    lib = new Qeda.Library
    lib.add 'Dummy' # Adding custom element 
    lib.generate 'dummy'

    And run:

    coffee custom.coffee
    

    Result:

    Symbol Footprint
