Sparse and passive reduction of massively coupled large multiport interconnects
The large number of ports in an interconnect structure is a critical limiting factor when applying model-order reduction. This is due to the fact that the size of the reduced model grows rapidly with increasing the number of ports, leading to large and dense circuit matrices. To address this problem, a novel method based on transverse partitioning and waveform relaxation is proposed for passive model-order reduction of massively coupled large multiport interconnects. The new method effectively replaces the tightly coupled multiport reduced model with decoupled 2-port subcircuits. In addition to preserving the advantages of model-order reduction, the computational complexity of the new method grows only linearly with the number of lines.
