Hierarchical techniques for symbolic analysis of large electronic circuits

摘要

A hierarchical symbolic analyzer (SAGA2) for the analysis of electronic circuits is presented. SAGA2 analyzes lumped, linear, or linearized (small-signal) circuits in the S- and Z-domain. For large circuits, a hierarchical two-port method is used that is two to three order faster than that without using the hierarchical method. Also, the memory used is dramatically reduced.
