Thanks for all the suggestions and comments!!
I will try all those suggestions just to I can figure out how they
work. For phase 1 of this project, I will probably go with the eval.
thanks again, happy hacking...

I think you're going to have to write a
Another example is a filter. From the CppSim doc:
Filter filt("1+1/(2*pi*fz)s","C3*s +
C3/(2*pi*fp)*s^2","C3,fz,fp,Ts",1/gain,fz,fp,Ts);

Overall I am trying to learn OOP by porting
CppSim (http://www-mtl.mit.edu/~perrott) to Python.
In CppSim, classes are defined that allow various functions to be
defined, like amplifiers. In some cases they are linear:
y = A*x
some have offsets:
y = A*x + off
some are non-linear
y = A*x - C*x
