Mixed mode circuit simulator SPLIT2 using dynamic network separation and latency

The authors describe a mixed mode circuit simulator called SPLIT2. They suggest a dynamic network separation technique based on the tightness of the coupling between subnetworks at the level of the Newton-Raphson stage. First, the dynamic network separation algorithm is described. Next, this algorithm is introduced into the simulator SPLIT with hierarchical decomposition and latency. The validity of this mixed mode circuit simulator SPLIT2 is verified. SPLIT2 can select the direct method or the relaxation method and determine the block size of the latent circuit dynamically by using dynamic network partitioning.<>
