Question: Symbolic circuit analysis algorithm for large networks

Some years ago I have read about the method of Determinant Decision Diagrams. With this method one can analyze relatively large electrical circuits symbolically (for example opamp uA741 as a benchmark) . The authors wrote they had implemented the algorithm in Maple. I wonder if anybody read about this or tried to implement this algorithm. It would be nice to have this capability in Maple.
