Converting from Eagle to KiCad.




  • Quick Introduction Video
    Recommended video player Firefox 43+ with VLC video player plugin
  • The following 5 ulp (eagle user script file) and one ulp include file, work together or stand alone to convert Eagle sch/pcb version 6.xx(7.xx maybe?) file(s) and any version of Eagle lib(lbr) to KiCad sch/pcb and lib/mod files.

  • The Programs will do
    • Eagle mulit sheet sch to KiCad mulit sheets.
    • Global and local net labels for mulit sheets.(This is a real nasty bit of hacking!)
    • Mulit part gate’s.
    • Build KiCad PCB modules and SCH libs from Eagle SCH.
    • Make project director to store all the converted files.
    • And basic error checking.
    • Eagle 6.xx PCB files can be directly import to KiCad.
    • Eagle LBR’s(any version of Eagel libs or size ) can be converted to KiCad lib/mod using eagle-lbr2kicad-1.0.ulp see
    • Eagle Lib conversion for more details.
    • Converts Via’s to Pads, which helps with KiCad’s flood fill, when Via’s have no connections.
    • Documents fill’s over SMD pad’s on Eagle Layer 155,156
    • Documents on layer’s 150,152,153,154 of (Eagle) the unconnected Via’s and tracks.
    • The examples director contains a number of converted sch’s/board’s.
  • By using the following ulp’s a consistent link from the SCH to PCB is maintained so forward and backward net-list annotations work under KiCad!

WARNING KiCad via’s and tracks don’t retain NET information from Eagle when they are not connect to a PAD!,** So KiCad flood fill will not connect to them !!! There is an option to convert and document on layer’s 150,152,153,154 of (Eagle) the unconnected Via’s and tracks which will make finding and fixing the problem much easier.**

Installing.

  • Download the zip file, (click on the button on the bottom right of this page. Download ZIP) And unzip using your favorite zip program to your target directory OR if your prefer git:
        git clone https://github.com/lachlanA/eagle-to-kicad.git  
    
  • WARNING: The ULP’s file-name will conflict with Eagles ULP’s file-name’s so
    DO NOT install them in Eagle’s ULP directory.
  • There are 5 ulp’s and one ulp include file have been hack together.
    renumber-sheet.ulp …………………… stage 1: Add missing number(s) to parts Prefix’s.
    fix_via_hack.ulp ………………………… stage 2: Converts unconnected Via’s to Pad’s.
    eagle6xx-sch-to-kicad-sch.ulp …. stage 3: Build sch and project files, etc
    exp-lbrs.ulp ………………………………… stage 4: Extract libs from eagle SCH/PCB
    eagle-lbr2kicad-1.0.ulp……………….. stage 5: Converts Eagle lbr to KiCad lib/mod
    eagle_to_kicad_include.inc ………. Include file used by the other 4 ULP’s

    HOW TO RUN THE ULP’S

    WARNING Always backup your Eagle SCH/PCB files before running this program!

  • 1: Start your Eagle program (Make sure your using version 6.xx of Eagle)
  • 2: Open the eagle SCH/PCB file you wish to convert. Make sure the eagle SCH and PCB file’s are both, Correct and pass all ERC/DRC checks in Eagle.
  • 3: Next Open the top left hand File menu and select Run ULP
  • 4: A file requester window will open. Using this, to select find or type the location of the renumber-sheet.ulp ULP you download from this website. We use this script to make sure all part prefix’s are ending in a number IE: R0, X1 etc. As KiCad will ask to renumber any prefix which dose not end in a number. (It may do this any way, but don’t worry it wont change any Prefix’s which have already been numbered unless you tell it too!) Keeping prefix’s consistent from SCH to PCB will allow net-list forward and back annotation to work in KiCad. Select OK (this will run the scrip). When this completes all references with out a number, should have a number appended to them. Note: This number will start from the largest reference number on the SCH/PCB.
