LIM-SPICE for the analysis of power distribution networks

This paper presents the implementation of a new LIM-SPICE simulator. The latency insertion method (LIM) is improved and integrated into SPICE as an accelerating option. Since LIM has linear computational complexity and is substantially faster than SPICE, the new LIM-SPICE simulator can simulate large linear networks with substantially higher speed within the SPICE simulation framework. In addition, mutual inductance between branches are handled by utilizing a K matrix formulation.
