Simulation Program

[John Boy]

One guy posted a message earlier complaining about a simulation
program he was using called VisualSpice that went into demo mode
suddenly, then he could'nt use it anymore.

Well I have that same program and the SAME BUG happenned to me too,
but it was not that big a deal, the company gave me a FREE fix for it,
and its been working fine for me since and I use it for my job every
single day with no problems.

I just used it to help design TWO working Satallite GPS receivers plus
lots of other stuff and no problems here. All SPICE simulation
programs can be a little tricky, you have to know what you are doing,
but they all work the SAME because SPICE is a standard from Berkeley
University.

Programs out there with zero bugs raise your hands....

The $99 price for VisualSpice I think it's a good deal, and personally
I think it's WAY easier to use than the $12,000 PSPICE. Using PSPICE
is even more complex because you have to run at least three programs
to do anything! What tha hell!!!

Besides PSPICE does'nt even have any built in test instruments. The
VisualSpice I have got a built in real-time 64 channel scope, logic
analyzer, live spectrum analyzer where you just click on a wire to see
the waveform during the simulation, or change the componet values
during the simulation was nice.

My main complaint is that VisualSpice claims it comes with 7000 device
models, but some models I wanted was'nt there. But, I just went to the
device model manufacturer web site, downloaded the model I wanted for
FREE, then imported it into the program, no problem. I heard they have
a newer version that comes with 25,000 device models for the same
price or a little more. Not too bad.

Yo! Just my honest opinion.

I wouldn't mind your spam so much if your c.r.a.p. program was not so
bad. You're so damned DUMB you can't even write a consistent three
paragraph tutorial- how stupid are you that you can't even keep track of
a three-component gate LED driver. The DEMO doesn't SIMULATE- because
you're so damned dumb you intercept the requisite SAVE operation and
terminate. Looking at some component PARAMETERS, I see you're so damned
dumb, you defaulted every timing parameter of the TTL 7400 family to
1ns. Your program is a worthless and malfunctional piece of trash, and
you're a damned dumbass who ought to get off his high horse and start
picking up litter in the local park so you can say you did at least one
useful thing in your lifetime.

My comments about the program (at least the demo version):
None. I couldn't run it, 'cause it REQUIRES A PRINTER to be installed - and I
don't have one. But I faked one by creating a 'generic' printer that dumped to a
file. Let's open... argh. The interface is c.r.a.p.

Your program is not worth any amount of money- I wouldn't use it if you

flaws- single line spacing- that ought to be good for an easy $10,000.

Not at all. Its certainly advertising, but not Spam. Not all
advertisements are Spam.

else doing that!!!! But I guess he needs the money.

Indeed.



This is an example of the the definition of SPAM.

Not at all. Many here post links to their own services.

Why dont you call
his posting SPAM?

Because I don't make posts, saying hey, try my SS as the theme. I
*respond* to other peoples post. By far the majority of times, SS don't
get a mention, other than in the signature. However, thanks for giving
me the opportunity to highlight SS as a direct response to your specific
issues.

Besides, Why are you calling me DUMB? Did I write
the program? A DEMO program is not fully functional as far as I know,
unless it says free FUNCTIONAL DEMO. Oh you probably missed school
when they were teaching about what FREE FUNCTIONAL means.

The SuperSpice demo is completely *fully* functional, and I don't use
that term. The only limit is the number of components that can be used.
Indeed, the limit is rather large, 30 on a top level, and 25 on a lower
level of hierarchy. This means that you can get around 750 real
schematic components with the demo.

I told you I use it every day for my job, how much you want for $99?

Good for you. If your happy with it, use it. For me personally, VS is
completely unusable. I don't know your background, but my own opinion is
based on my personall experiance, over 20 years of professional analogue
design at both i.c. and board level. Do you want a real list of its
faults?. It was partly because of programs like this that I wrote SS.
Why don't you try another real, affordable, simulator that is really
usable.

I dont have $12,000 to buy PSPICE just so that I dont have to set a
default printer ONCE when I first run it. Besides even PSPICE got bugs
in there too.

Hey why dont you stop whining, go pimp out your mother to raise
$12,000 then use it to buy PSPICE. Then maybe you will shut up and
crawl back under your double wide.

I have a right to post my opinion just like anybody else. Why is your
opinion any better then mine?

What's you background then. Do you have extensive experience as an
analogue designer?

Seems like you are trying to get
attention by making fun of other peoples stuff, were you a bully when
you were in school?

It was an unsolicited opinion that gave the impression that it was a
company sponsored direct advertisement. The whole stucture of your post
come over as Spam.

Oh here's a thought, If you are so smart, why dont you WRITE YOUR OWN
SPICE PROGRAM then post it so that we can all download it to see how
it's "supposed" to be done, I dare you!!! Give us a date when we can
download your "Gods Gift to Simulation"

Writing a decent program is not difficult in itself. Its simply the time
it takes to write, and having knowledge of what is actually required.

Why do you keep calling it MY program? Are you that stupid? Since when
is posting an opinion about something automatically grants ownership?
I wish that were so. Besides I wouldnt pay you to wipe my nose.

Maybe you never said anything good about anything in your life, it
must be a foreign concept to you. You must be related to my wife, talk
bad about everybody else, but never do anything themselves so that
nobody can say bad about them.

Why dont you put your money where your mouth is and post a program YOU
WROTE so we can all see your expertise! I need a good laugh. Come on,
post your program so we can see the art of computer science.

I expect that your next posting in here will include a link to the
state of the art program that you wrote.

It's a signature. If you want, you can just scroll up and not read his

unless it says free FUNCTIONAL DEMO. Oh you probably missed school

That's called 'Student Version' or 'Evaluation Version'.
Look at SIMetrix Intro, for instance. You can use it to do circuits with 2 or 3
op-amps. Enough to be useful for students or hobbysts.

I told you I use it every day for my job, how much you want for $99?

LTSpice is FREE and fast. SIMetrix (my favorite simulator) starts at $500 IIRC
(for the version without IC design features). SuperSpice starts at $30 or so
IIRC for the Student edition.

Look at SIMetrix Intro, for instance. You can use it to do circuits with
2 or 3 op-amps. Enough to be useful for students or hobbysts.

I'll add my voice to stating that SIMetrix is a very worthwhile tool. I
liked the free version so much I eventually purchased a more full-featured
version. Unfortunately, now that SIMetrix is a part of Catena, the prices
have gone up significantly. For a 'real company,' the increase isn't enough
that it would kill anyone's budget (and it's arguably still a good deal),
but it does tend to at least give it the appearance of moving out of reach
of the 'enthusiastic' hobbyist. I've found Newbury Tech. (the makers) to be
quite reasonable about considering the end use in their pricing, though
(i.e., academic, hobbyist, Intel, etc.), even after the move.

I had actually tried out SuperSPICE beforehand and -- while it did convince
me that Kevin's a pretty darned savvy guy and cares a lot about the
program -- found it still a little 'rough' around the edges. The pricing is
quite attractive as well.

I haven't used LTSpice, but wouldn't be surprised if -- given a few more
years of development -- it rapidly starts kicking (the free version of)
PSPICE off of many college campuses. PSPICE works just fine, and OrCAD can
point to many real world successful designs with it, but I think it's
difficult to argue that it's really the best bang for the buck anymore.

Finally, as for the guy who stated that 'all SPICEs are the same at their
core anyway' -- that's probably quite true of the many SPICE packages that
just wrap a GUI around the Berkeley core, but what you're paying for with
the likes of SIMetrix and SuperSPICE are guys who understand how the
Berkeley core works _and have made extensive modifications to it_ to support
better performance, convergence, etc. Not to mention bug-proofing --
there's a lot of academic code out there that's choke full of bugs due to
the people writing it knowing that (1) they'd probably never get any credit
for making it rock solid anyway and (2) that thesis deadline was coming up
awfully fast...

I WAS responding to another post about VS, but their post was over a
month old so I had to start a new thread.

Personally I dont want to argue about stupid spice programs, you
people use anything you want, what do I care. All I did was post an
opinion, yes I admit it did sound like SPAM, so what, maybe they'll
give me a commission for it I need the money for a new computer
anyway.

I design circuits for a living also, but I dont have 20 years
experience, why do I need it, I'm not designing with vacuum tubes.
Typical engineer thinks he knows more than everybody else, and only
his opinion is the right one.

Of course YOUR program is the ONLY usable program in the world. But I
tried yours and I couldnt get it to do anything because it was too
slow even if it was the only thing running.

Honest bible truth, I clicked on a menu item in SuperSpice and it took
like a minute before the menu poped up. The hard drive started going
like mad each time I tried to pick something from the menu. Are you
creating the menu in real-time on the fly each time you try to click
on it? why?

I had to start plannng ahead of time what menu item I'm gonna click
next because if I made a mistake I would have to go eat a sandwich
while waiting for the correct menu to come up. It reminded me of the
time I tried using the Protel demo, unbelivable, you need a 3Gz
machine for that thing.

But SuperSpice could be a nice program, but I could not give it a
good try because of the speed problem. If you get that fixed maybe I
could try it again. It looks identical to VS, so maybe it's good. I
think you programmers are copying each other.

I tried Electronic Workbench, forget that one, you need a 3Gz dual
processor machine to boot that one up. PSPICE was ok but I gotta run
three programs to get a simulation. CircuitMaker was ok, but the
interface was clunky old pre Windows 3.1 style and cost $1000. Beige
Bag B2 Spice was ok but clunky interface also.

They are all basically the same under the hood, because they all use
the exact same SPICE engine from berkeley and then add some fluff to
"pretty it up". Then charge you a lot of money depending on how pretty
it is.

My opinion take it or leave it!

SuperSpice doesn't normally suffer from such extreme speed problems. It
