Introduction

asysc is an analog system compiler based on the lightweight Computer Algebra System lightcas.

With ASysC, you can write your own components by using algebraic descriptions. For instance, consider the resistor declaration:

NAME.CR(@1,@2,R) := { 
    NAME.U=ACROSS(@1,@2); 
    NAME.I=THROUGH(@1,@2); 
    NAME.U=R*NAME.I 
};

For more examples, see the component.rule and examples directories.

The analog system compiler is invoked with the following command (Example with the RLC circuit in AC mode analysis):

cd examples/ac/RLC
../../../lightcas/bin/asysc -i RLC.cir -o RLC.py -t ac

This command generates Python code containing equations for AC simulation.
