Of course, but can you imagine how much work that is?
It must be a compiler because of speed. Model evaluation is the
biggest factor in run time on large circuits. Gnucap pays a
lot of attention to minimizing the number of model evaluations.
The so-called "fast spice" simulators take several approaches to
making them faster. Gnucap is one of the first. It can be the
fastest if you are willing to lose accuracy. Just using
simpler models will go a long way.
To keep the speed, and actually get something done, I decided
that the best approach is to use an external compiler.
If you don't have a compiler, gnucap will still run, but with
limited behavioral modeling capability. Anything Spice can do,
gnucap will do without the compiler.
Nosy question that nobody will answer: How many of the
commercial proprietary simulators use gcc under the hood?
