Direct symbolic analysis of large analog networks

A new symbolic analysis approach for large analog integrated circuits is presented in this paper. It is based on the Coates graph representation and nodes exploding technique for construction of symbolic formulas. It can symbolically analyze large analog ICs without circuit decomposition. There are no limitations for the circuit topology and size. The analysis time and the memory required to store the symbolic formulas are estimated to increase pseudo-linearly with the number of the circuit nodes.
