    PCB Editor Libraries Reply
    I am looking for a new set of libraries that runs with Allegro PCB Editor.  My old libraries have footprints that are valid with Layout Plus but not PCB Editor.  I do not want to take a design through layout then convert the ".MAX" file into a ".brd" file.  So, where can I find libraries that have the proper footprint already enabled for Allegro PCB Editor?

    Make them manually,

    find them from vendor, like

    http://www.analog.com/en/pcb-design-resources/content/pcb_design_resources/fca.html

    buy them from someone else

    buy a tool that makes them for you e.g. pcb matrix lp wizard

     This seems strange to me.  How can a company have a product but not supply a key component of the program?  Because there are no footprints in majority of the packages, I can't export a netlist to view my circuit in Allegro PCB Editor.

     Greetings,

    Library management is one of the most important facets of PCB design. Accordingly, there are many ways of creating symbols and conventions. Many end IC vendors will have a different footprint for the same package type. It would be impossible for EDA vendor to keep track of all these variations. A library is also a marketable item. Each company generally has a librarian that has developed a system that works for that company. Cadence does provide a basic library that you can modify as you desire.

    Cheers,

    Ron Scott CID+

    It sounds like you want the schematic symbol's footprint property should match a library name in Allegro?

    Cadence ships with a fairly extensive schematic library with Capture (OrCAD) or Concept.  Also, when you install Allegro you will get all of the Cadence footprints.  Your job is to match the symbol with the footprint.

    As the others have said, it's your job to make sure it all matches.
