Still waiting for a Ltspice expert answer.

Stay away from open flames, Maynard. You would burn down the whole
trailer park, if you caught fire.

Jamie/Maynard/WTF is just one banana peel short of insanity... and yet
he's smug about it.

He has no clue of the technical competency of 'qrk' who properly
advised, "Do you blindly trust your models??? If you do, beware, they
are often wrong. With experience, you will learn a healthy distrust in
your simulator and test equipment."

I happen to know 'qrk' quite well. His company was a past chip design
customer of mine. 'qrk' really knows his stuff.

Yet Jamie/Maynard/WTF smart-mouths his superiors. Time to shun him
into non-existence.

than that.

If seems your above statement is completely contradictory to what I
stated by Ltspice not being reliable, spice in general i guess and bench
equipment is the only truth.

Oh well, I'll just past it off as age on your part. I have an aging
father in-law and I see the resemblance.

Just goes to show how some people are not able to make proper
assessments of others. Most of those generally do not become management.

Glad you added "test equipment" Too often THAT is trusted more than
it warrants!

I embarrassingly once spent 4 hours tracking down, yes, test equipment
problem, not a circuit problem! Learned a healthy respect to distrust
EVERYTHING, That even includes distrusting the values marked on the
components when you breadboard - especially after using 10 ohm
resistors marked as 1k And, worst of all? a bad lot of IC's! It is
surprising how much one blindly trusts incoming parts more than they
trust their own designs to work properly. Now I don't even trust data
sheets to accurately describe a component. Once, Intel's spec sheet
was so wrong that my software group worked 6 weeks trying to 'fix'
their software, all wasted time, all caused by an error in Intel's
data sheet! When confronted, Intel's response was, oh, yes, that is
an error. Thanks a lot for the heads up!

All of the above experiences really describe why one should NEVER
trust a 'garage' design. You know, the design works, so build more
just like it and start shipping.

After the above experiences, I now trust well worded Buying Contracts,
and well documented designs with verification testing using test
equipment traceable to the N??? standards. Now, when you do that;
THERE is recourse if something doesn't work right.

the company, and it only takes a few seconds to find his public

would be enough legal reason to fire him.

More than once I was called from my bench to see what was wrong on a
test setup, to find the problem in seconds becasue the tech didn't
follow the procedure to verify the test setup was working. Things like
not bothering to zero the offset voltage on a function generator, then
failing boards becasue the 'video' output was against one rail. It
would piss me off, because I had taught them the proper procedure,
before giving them the product to work on.
