Now please present us with your "solution" with component names and
values and I'll simulate it side-by-side with my design.


I rarely simulate. Design is the reverse of simulation. Design forces
the desired results, so why simulate?

So you've been converted to the Bob Pease school of hand waving ?:-)

My POV: Design puts the idea onto paper. Simulation proves that what
is on the paper really works. But simulators don't "design". In my
business, simulation "proof" is required for each and every process
corner, otherwise the customer doesn't "buy".

I used to be in Larkin's corner, defending "build and test" over
"simulate", but after writing a few simulators to solve specific
problems posed here on sed, which couldn't be solved, practically,
any other way, I decided to lay down my wire-wrap gun until the
machine worked in the computer.

Then, along came wonderful, free LTSPICE.

I've designed stuff using it which I never had to physically build,
but which worked and which I got paid for, which is a joy.

A feeling I'm sure you enjoyed before I did. :-)

It took me MANY years to trust simulators. Initially even bipolar
device models were bad.

But I still "design" by first "sketching", even if the "sketching"
does use a schematic capture program... I'm faster that way, no
erasing... drag stuff around... such fun!


You don't drag them, you push them around! ;-)
