    Thanks in advance for any info.

    Best free? Best at any price? (Got a Cray in the basement?) Best for
    hobby use? Best for 90 nm silicon layout?

    Let's make two distinctions:

    a. Best for hobby use at a reasonable price, say US $ 300.
    b. Best for professional use (without taking price in account).

    LTSPice from Linear is free and well thought of around the newsgroup.

    In the low price range, I've been using BeigeBag for years (since they
    were selling it on 3.5" floppies in real brown paper bags). They've
    recently done a re-write to the codebase for their V5 release and, while
    there still are a few rough edges left from the move, it's a good
    product. Interoperates with Eagle CAD.

    Can't help you on the very high end stuff, tho.
  5. "Best" never exists. What are you trying to do?

    SuperSpice, a very affordable Mixed-Mode
    Windows Simulator with Schematic Capture,
    Waveform Display, FFT's and Filter Design.

    SIMetrix SPICE has a good reputation. It's included with the Pulsonix ECAD
    software I use.

    Here's one for RF & Microwave , AppCAD Version 3.0.2

    gerbtool.exe ,

    linesim.exe , ,

    Impedance calculator / PCB stackup SB8000 combined package
    for multi-layer boards ,
  8. What exactly do you mean by A/D?

  10. OK, and do you intend to simulate A to D converters or are you looking for
    general purpose simulation software? The best deal out there for general
    purpose software is LT Spice (aka SwitcherCad) as it is free and works well.
    You can't go wrong trying it.

    If you are willing to purchase a high-end tool for IC design, I would
    suggest Ansoft Nexxim.
    Its new algorithms are about 5 times faster than current tools on the
    For example, if you are simulating a PLL netlist for 4 days, you can
    get the same transistor-level accurate results in less than a day. The
    same holds for difficult simulations that include post-layout
