Gate Deisgner?

[QuickHare]

Hi all,

Hopefully I'm not repeating a question asked many times before, but I did try to
search the net and found no answers.

I'm interested in logic gates, and would like to know if there are any pieces of
software out there that allows be "wire up" theoretical gates on the screen,
edit the wiring, see what happens with certain inputs, etc. I'm not looking for
a piece of software that does the wiring for actual physical components, just
something that will allow me to connect an AND gate to a NOT, from an OR to a
NAND, etc, to build up a logic diagram.

Any ideas?

Of course, in an ideal world, free is good... ;-)

well for a beginner, I would suggest "Electronics WorkBench"
there are others including free one's i'm sure others will
tell you about .

That will give you an idea.

and here comes one now! ^_^

The Beige Bag spice products include logic simulation and there's also
an older, stand-alone logic simulator available. Demo versions (that
revert to "Lite" versions after the trial period) are available at
http://www.beigebag.com/demos.htm#v5

Just a satisfied customer who has been using BB products from the days
when they really were packaged in little brown paper bags.

Download Quartus from Altera www.altera.com
With that you can build your logic out of primitives and simulate it.
You need to register it, but its free.

TkGate is free, open-source, and is likely at the feature/complexity level you want

See www.play-hookey.com for lots of fun.

Also, why not just get a white solderless protoboard and a power supply
for $20 and some 25 cent gate chips from Rat Shack and have at it?

If worse comes to worse, use BASIC or any programming language and
tie the propositions together with Boolean variables?

I would like to thank everyone for their contributions, they were all
interesting. I was unable to find free versions of most things listed, and what
I did find weren't Windows compatible.

I do program in BASIC myself, but I wanted something graphical to drag and drop
about the place. TkGate seemed perfect for my needs, except it was Linux-based.

Not to worry, I shall continue my search. I have learned a few lessons from
this, such as to look for "logic simulators" rather than "editors" and such
like, so thanks for all your help!

I'll post back if I find anything worth sharing.

Thanks again!

If you haven't already, use Google, to search for "logic simulator"

You might find what you are looking for.

I like Logisim, free, easy to use, and cross-platform:

switcher cad III (AKA LT-spice) has gates and flip-flops etc... and a fairly
simple user inteface where you just draw lines on the screen to connect them.
it's a free download from the linear technology website

The only problem is it doesn't do interactve input, but you can use programmed
voltage sources instead.

Electronics workbench is easier in that you can do interactive input but the
version I was exposed to seemed unstable.

If you are still looking, try googling for: CircuitMaker 6 Student
Its free for student use, runs on Windows 9x up, supports up to 50
components in a circuit and in its digital simulation mode switches and
indicators are fully animated so just point and click to test your circuit.
