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

Using a Computer Algebra System (CAS), you can write your own components by using algebraic descriptions.

Description example for a resistor:

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

Once the libraries and netlists are compiled, the Python code is generated for simulation.

- g++ or clang
- make

- numpy
- matplotlib

git clone https://github.com/analog-system-compiler/asysc.git
cd asysc
git submodule update --init

make clean
make

make run

To execute a particular test, type:

cd examples
make
cd examples/<directory>
python3 simulation.py
