Well, thank you too--I appreciate it.

Actually, that's not the worst part of the process. Yeah, I suppose it can get a little tedious, but it tends to be straightforward once the parts in question have been described, and you can learn about the functioning of the circuit as you go. Plus you don't have to do it all at once; you can focus on a portion of the circuit, get that working, and then concentrate on a different section.
The real source of potential heartache and frustration is when you have completed the netlist and then find that it won't emulate at reasonable speeds without serious work. Much of the trouble I had with 280-ZZZAP was due to this. Several of the oscillator circuits are numerically unstable, and it was hard to get the solution process to work without making it so slow as to be useless. We also had to figure out how to emulate LM3900 op-amps more efficiently; they are a bit peculiar. There was a lot of trial and error involved.
> I know the net-list process is more than just programming. Knowledge of electronic components is a must to make this happen.
Indeed, I had to learn a lot about analog electronics even to get to the point where I could do this, and I've been learning still more in the process.

Thank you again for your support.
