    geda Problem :

    When I open a schematic I am getting on the status bar
    Did not find optional gschemrc and gafrc file....

    Where are these files ?

    The system does pick up the system-gschemrc file
    from share/gEDA/sym/


    gschem Problem:
    I am using the components from gschem and want to
    add my models. When I query the component I do not
    see "model" and "model-name" attributes to my
    model.

    I using the transistor from the analog library.


    Thanks

    : Where are these files ?

    : The system does pick up the system-gschemrc file

    Some RC files are optional, some are mandatory:

    system-gafrc -- mandatory
    system-gschemrc -- mandatory

    user's gafrc -- optional. NOrmally in $HOME
    user's gschemrc -- optional. Normally in $HOME

    local gafrc -- optional. Normally in local direcctory
    local gschemrc -- optional. Normally in local directory.

    The files are set correctly when you install gEDA. The user and local
    gafrc files are optional files for you to create if you wish. If you
    don't create them, no problem.

    If gschem runs when you start it up, and you can get to all components
    in the libraries, thne you are fine. The warning you see is just a
    warning.

    : see "model" and "model-name" attributes to my
    : model.

    You need to enter these attribute names manually. Type them into the
    appropriate spot in the attribute editor.

    Wow this is cool. I have been using PCB (the layout
    program for some time now under Solaris).

    Having problems building GSCHEM under that
    environment so I installed the Windows port from
    2002

    Is that what you guys are using?
    Did you build more recent ports?

    Nice to know others are using these open source
    programs. I did a 2 layer board with PCB last
    month ... I have a 4 layer board planned for the
    next few months

    actually there is a recent release which you can burn on a CD and
    it auto configs and compiles/installs. I haven't tried to build
    it under Solaris or Cygwin, but use it under Linux.

    http://geda.seul.org/download.html

    I think the most recent version is 20050329.
    I have been using PCB on SunOS/Solaris/Linux for almost 10 years now
    and have several 2, 4 and a 5/6 layer board. It has been getting better
    and better over the years.

    I just completed my first completely gEDA based design, a 2-layer USB
    programming dongle for Rabbit microprocessor. The design is mostly SMD
    parts (0805 and QFP32) and I even used the autorouter in PCB. I had to
    touch up some traces from the autorouter. They were functionally
    correct and passed DRC, they just didn't look "pretty" enough.

    I haven't tried this; PCB understands size attributes in the netlist
    (like Power,Signal,Skinny, etc...). I haven't figured out how to set
    the attributes in gschem and whether/if gsch2pcb can understand and
    generate them.

    Other than that, it's very very very nice to be able to do this all
    under Linux. I used to have to switch to windows for part of my toolchain.

    See ya, -ingo
