UK question. SPICE software on coverdisks

[gazza]

Group,

I'm trying to find cheap full versions of SPICE based circuit design
software (e.g. Tina, Circuitmaker etc). The newest versions tend to
cost
ŁŁŁ, so I wondered if anyone could suggest coverdisks from back issues
if magazines that had full versions on.

Regards,
Gary Pearson.

How about LINUX? If acceptable, the "gEDA" can be good solution.
It is free. Take a look at www.geda.seul.org

It's darn near impossible to beat the value offered by
LTSpice/SwitcherCAD III from Linear Technology. Not only is the
full-up program (no size limitations, no nag-screen, no crippled
features) free, but they don't charge for it!! For personal, student,
hobbyist or even semi-pro users there are few programs that offer more
features and none that do so at that price level (zero cost).

Download a copy (about 5 meg filesize) from:
<http://www.linear.com/software/>
The current version is 2.06X dated 5 Nov 2003.

A neat feature is that the program is under active development, and
updates (typically bug fixes and new models) are posted approximately
once a week. Notable enhancements and added features appear every
month or so. On a 'net-connected computer (is there any other kind
these days?) the program will actually update itself if you select the
"Sync Release" entry on the "Tools" menu.

There are probably special situations where you'd select somebody
else's low-cost program (e.g., an original IBM XT, with DOS 6, will
realistically run the student version of PSPICE 5.5 if you have a
coprocessor!) but I'd need a good reason NOT to go with LTSPICE.

However, the demo version of SuperSpice http://www.anasoft.co.uk is
actually able to do just about all hobby projects. You are allowed one
level of *schematic* hierarchy. This means you can place 30 blocks on a
top level, and 25 real components per schematic block. This means 750
real components. In addition, you can one button press make a .subckt of
those blocks essentially allowing for an unlimited number of components.

There are also no feature limits at all in the demo SuperSpice, of
course, theres still that nag screen...

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

Understanding, is itself an emotion, i.e. a feeling.
Emotions or feelings can only be "understood" by
consciousness. "Understanding" consciousness can
therefore only be understood by consciousness itself,
therefore the "hard problem" of consciousness, is
intrinsically unsolvable.

Physics is proven incomplete, that is, no
understanding of the parts of a system can
explain all aspects of the whole of such system.

I don't see why these component limits should be a problem even for
serious developers. Who wants to have spend valuable time scrolling
through a large circuit to get to the bits they want, anyway? Far
better (surely) to treat any project as a series of stages and develop
each seperately; just simulate the signal characteristics from the
output of one to the input of the next. If the signal characteristics
are accurately rendered, there's no need to work on anything more than
one, easily managable stage at a time, IMV.

Well, quite. The price of Guinness is shocking.

Try reading the 'Bluffer's Guide to Philosophy' available from all
good bookshops for less than a fiver.
