Need a Design Tool to Do Large Data-Flow Diagrams and State Machine Logic ...?

Discussion in 'Embedded' started by David T. Ashley, Apr 18, 2005.

  1. Hi,

    I'm reverse-engineering some embedded software that is best viewed as
    processes that communicate via shared variables.

    I'm looking for a design tool that will do large data-flow diagrams (like,
    plotter size), and will also capture state-machine logic.

    UML notation would be of interest, but not strictly necessary.

    Any recommendation or pros and cons?

    Thanks, Dave Ashley.

    I use Microsoft Visio for this - the professional version supports UML
    and flow diagrams (among many, many other stencils). Whether or not it
    will choke on plotter sized diagrams depends on your machine.

    You might also want to check Rational Rose... I used it 5 years ago
    when Visio didn't support UML. It was funtional... but ugly.

    Not sure about the print/plot-size, but check out www.rff.com

  5. You can try EventStudio 2.5.

    EventStudio will let you define data flows as sequence diagrams.

    Poster size diagrams with a very large number of entities are
