So what? You want the simulator to hold the hand of the person using it
(I am not advocating that) or do you expect the person using it to know
what is behind the simulation tool? The latter would require another
several courses of schooling for the user and would not solve the problem
at hand. You could go to school forever and not know enough to write a
Spice program that would converge no matter what. If you want the tool to
aid the average engineer, then do that much, but when he doesn't know
about a given portion of the algorithm behind the Spice, don't give him a
bunch of Academic grief to the point that he won't use Spice at all. When
I first started work as an engineer we built a circuit and made it work.
We then built lots of them and made them work. We then shipped the final
product. This was silly and time consuming. Now that we have the
capability to do otherwise, we should. Make the design tool and not a
design instrument. Please give the new guys some breathing room.
