HIE-block latency insertion method for fast transient simulation of nonuniform multiconductor transmission lines

This paper describes a hybrid implicit-explicit block latency insertion method (HIE-block-LIM) for fast simulation of nonuniform multiconductor transmission lines. In the HIE-block-LIM, an implicit difference method is used with respect to the current variables in one direction, and an explicit method is adopted to update the other variables. The HIE-block-LIM can alleviate a time step size limitation of the existing block-LIM by taking both advantages of the explicit and implicit difference methods.
