SW that would draw a switching circuit

[Newberry]

Hi, does any SW exist that given a Boolean formula it would draw a
switching circuit? Thanks.

Not that I know of, but given a boolean formula I can then reduce it
and implement it quite simply. The implementation method would depend
on the complexity and overall cost, power consumption and stability of
the various options, of course, depending on the design parameters of
the system it is part of.

Why do you ask?

[I do note it is Sunday night and a lot of students are scrambling to
get their first pieces of major homework done and in to the instructor-
there have been a lot of obvious homework requests today on usenet].

I am studying some aspects of Boolean algebra and a switching circuit
sometimes gives me a better intuitive understanding of a formula. By
"switching circuit" I mean AND, OR, NOT gates. I am not too concerned
about power consumpton, fan in, fan out at this stage.

It is surprising that such a SW does not exist. I presume that SW for
circuit design does exist. So how do you use it? You drag and drop the
icons and connect them manually? BTW, I am not a student doing homework.

You're acting like one.

A minimized Boolean expression can be reduced to schematic by trivial
observation.

I can't see an application for this type of software. Even for educational
purposes you can better do the drawing by hand. More complicated designs
will not be documented by drawing gates. The formula defines the required
function and is programmed into a PLD or similar device. These days Verilog
and VHDL are the tools to design logic circuits. They have the possibillity
of schematic capture but do not translate formula in drawings. As I said, I
see no use for it.

Not bad, but when I click Map --> Fill with --> Formula nothing happens.

I guess you'll have to visualise the gates yourself.

Without wishing to seem mean, I wonder why you think such a tool will
help you. I can visualise virtually any gating arrangement from a
boolean expression (and I can minimise it, of course - can you?).

If I can not visualise it, I draw it, which is not difficult. I am at a
loss to understand why you want a computer to do this for you if you
are trying to understand it.

Actually, the software for hardware design exists, but there is no
software that exists to actually *design*. That is the realm of
thought.

There are limits on software (the ability of the writer comes to mind).

Hi Petrus,

It looks quite nice on the website. Have you personally used it?
Thanks!

It will save me time + it will look neater.

Had the older free version which supported formula input, upgraded to
the current free version which has more variables but formula input
appears to be disabled. Have not found a practical use for it since a
truth table and a piece of paper usually suffices.

I can do 8-inputs by hand, but it's a pain. It certainly looks like
it's worth $40 (pro version).
