Turbo-SPICE with latency insertion method (LIM)

In this work, the latency insertion method (LIM) for the time-domain simulation of networks is incorporated into SPICE3f5 for the faster simulation of power distribution networks. This integration is done so as to provide an accelerating option for simulation and an alternative to the resident modified nodal analysis (MNA) in SPICE. Since LIM has linear computational complexity and is substantially faster than SPICE, the new LIM-SPICE simulator allows to handle much larger networks while using the same SPICE framework. In addition, mutual inductance are handled by utilizing a K matrix formulation.
