Indeed. All religions are residues of times when people knew no better
than to say, well mate, it was all made by this invisable alien that can
do anything, know everthing, and be everwhere...yeah sure...and pigs can

well, I have recently used verliloga models supplied by cadence, and
they have offsets, slews etc all parametized. You need to set them of

Reminds me, I need to add offset to my Configurable OpAmp model. I
already have slew rate, GBW and excess phase modeled.
And more importantly, how to correct/set them up so that they can be
trusted.
Yep!

MOST models should be viewed with a jaundiced eye.

Yep, I was using models a friend had once. I couldn't believe the
speed of the circuit I was designing. A kept cranking the step
interval down to get a good look. The idiot had divided all the
cap values by 1000 without telling me.
But that's how we separate real engineers from the little boys...
knowing when to trust simulations and when to not.

Sure, but even I didn't believe the speeds I was getting (the Ft of
the devices I was using were "only" around 7GHz). ;-)

Looked at any SiGe recently, fT > 35GHz+

Wasn't available in ~'76. ;-)

What subset of the population do you want as customers? Not, presumably,
the 50% of Americans who attend church.

What other exclusion criteria are you setting up? Those of us who wonder
whether to do business with you want to know.

Yes.

The issue with the novices in here, is that they make all these daft
claims that spice isn't up to the job, when the reality is that they are
not up to the job of using Spice.

Its like claiming a PhD math expert shouldn't be using MathCAD, or a
carpenter shouldn't be using a power drill etc. One has to learn how to
use the tools of the trade *correctly*. This can take many years for
some.

Well, I was thinking that Anasoft might not want to repel potential
customers, if Anasoft is in business to make money.

I have principles. Given a tossup being money and the truth, its a no
contest for me.

Giving credibility to pixies, elves, Santa Claus and gods, is the sign
of a twat, potential customer or not.

Anyway, my day job is as an anlogue i.c. design engineer, SS is just
pocket money.

On the other-hand, there are many who don't go to church, and do not care
what religious belief someone holds, and many who do go to church and don't
care, and this more than balances all the bigots like you. You may assume
anything you want about my religious position and I don't care.

I'm sure his business will do well without you.

I'm a bigot? Huh? You may have misread something.

I don't care what religious belief he holds (at least, it has nothing to do
with whether I do business with him). But *he* objects to religious people,
and says so right under his advertisement, which led me to wonder whether he
also wants to exclude other large groups of potential customers.

No, you didnt design it then, you just copied (replicated) something
else you already knew worked. The *only* way to know if something
actually works, is to measure if it works. Even then you could be
fooled.

Are you actually incapable of designing an original circuit that you
are confident will work? I do that all the time. I dislike copying
circuits, even my own. Sometimes I do a little math, sometimes even
use a calculator, and sometimes sketch a Bode plot or such to check
closed-loop stability. Simulation is reserved for just the rare,
really hardcore cases.

Of course it gets tested after Production builds the first, sellable
article, but all that simulation/breadboarding time was sliced out of
the critical path.

Pardon? So you think that praying to gods is worthwhile? Yeah, right on
dude. Many your gods have mercy on your souls.

I seriously pissed off a guy a few years back, who hassled my atheism
after preaching at me. I pointed out he shouldnt get so upset, his god
is just one of the many I dont believe in.

after preaching at me. I pointed out he shouldnt get so upset, his god
is just one of the many I dont believe in.

I terrified one at a video arcade once. Some guy came up and started
preaching, and I said, "It's too late." He said something like "It's never
too late for Jesus." I said, "No, I mean too late for you. I'm a Diabolist,
and if you're not out of my sight in three seconds, I'm going to put a
curse on you."

The only other time I've seen a human move so fast was the guy in the
intake of an A-7 when the rest of the crew acted like they were going
to start the engine. ;-)

As I have explained many times. The only way to achieve something truly
new is for that newness to be achieved by randomness. If it is random,
by definition, it operation can not be predicted with certainty.

Of course, I have designed many circuits that are "novel" by combining
existing circuits (cross coupled genes) that have worked 1st time. In
these case one can make a prediction based on existing knowledge.

I do that all the time. I dislike copying
circuits, even my own.


You still dont get the point. Its strickly imposible to design a "new"
circuit without copying something. Again, I have already explained, that
one must use *existing* knowledge (i.e. copying) to produce a usefull
design, for example, one will use diff pairs, current mirrors, cascodes,
push-pull outputs, salen-key filter, etc.

To obtain a totally original circuit you must use a pifetz, connected to
wizbangs, driven by gottenburgs, and you no can't connect them up with
wire, thats already been done, so not orginal.

Tell, when and how did you manage to invent these new physics
components?

You are not doing complex analogue designs then. Its that simple.

I think you are not being honest with yourself, or simply not
understanding what it is you actually do or what I am saying.

Whether a circuit's discovery is random or divinely inspired or
whatever, the predictability of its behavior can be evaluated
independent of its origin. Randomness is not a permanent pollutant.

Or are you saying that you only trust and use circuits that someone
else has already used and proven to be reliable?
