dc.description.abstract | The verification of integrated Circuits (ICs) in deep submicron technologies requires that all mutual inductive effects are taken into account to properly validate the performance and reliable operation of the chip. However, the inclusion of all mutual inductive couplings results in a fully dense inductance matrix that renders the circuit simulation computationally prohibitive. In this paper, we present efficient techniques for the solution of the linear systems arising in transient analysis of large mutually inductive circuits. These techniques involve the compression of the dense inductance matrix block by low-rank products in hierarchical matrix format, as well as the development of a Schur-complement preconditioner for the iterative solution of the transient linear system (which comprises sparse blocks alongside the dense inductance block). Experimental results indicate that substantial compression rates of the inductance matrix can be achieved without compromising accuracy, along with considerable reduction in iteration counts and execution time of iterative solution methods. © 2019 IEEE. | en |
