Efficient model order reduction via multi-node moment matching

摘要: The new concept of multi-node moment matching (MMM) is introduced in this paper. MMM technique simultaneously matches the moments at several nodes a circuit using explicit around s=0. As compared to well-known single-point (SMM) techniques (such as AWE), has advantages. First, number required by significantly lower than SMM for reduced order model same accuracy, which directly translates into computational efficiency. This higher efficiency increases with inputs circuit. Second, much better numerical stability SMM. characteristic allows calculate an arbitrarily high approximation linear system, achieving accuracy systems complex responses. Finally, highly suitable parallel processing especially approximations while sequentially and cannot be adapted techniques.
