    Hi all,

    Does anyone know any free or open source software(s) can simulate
    digital volt meter, oscilloscope and generate the final PCB layout from
    it?

    Thanks,
    Jimmy

    Did you take English lessons ?

    Mmmm... LTSpice and gEDA, perhaps?

    Google "free eda tools" or something; you'll get plenty of hits.

    Thank you very much for all pointers :) And I'll look at them later.
    Have been playing with Verilog lately which triggers the interest back
    to some good-old electronic theories.
    Wouldn't it be nice to write code in Verilog then _convert_ to an
    electronic schematic diagram for analysis, or even _produce_ a PCB from
    it and have a working circuit ... by using the same software tool!
    Guess there's no one tool does it all, right? If there's, it won't be
    cheap ... well, not affordable as a hobby ... for now.
     
  6. I skipped simulating the digital volt meter, oscilloscope and
    generating the final PCB, and simply bought both of them.

    Not really. Unless you're doing a really large Verilog design, it'll most
    likely fit into a single part (e.g., FPGA or CPLD), so there's little point in
    the guys who write Verilog synthesis & place/route tools to try to do PCB
    design as well.

    The big-guns of HDL simulation -- ModelTech and Aldec -- do have integrated
    design entry & simulation, and you can probe around during a simulation on a
    "schematic" that contains, e.g., block diagrams of your Verilog modules.
    Although they're calling external programs to do it, they also provide
    seamless synthesis & place/route from within their IDEs. In general the best
    EDA solutions end up using different vendors tools for solving different
    problems, but try to tie them all together in a nice "flow."
