Talk abstract:
On the Stability of Partial Element Equivalent Circuits for the
Electromagnetic Modeling of VLSI Interconnects
Albert Ruehli, IBM T.J. Watson Research Center
The Partial Element Equivalent Circuit (PEEC) model technique is an
approach for the modeling of tree dimensional geometries. One of the
applications is the modeling of VLSI interconnects on chips and
packages. For these problems time-domain solutions are of interest.
We will give examples of time-domain PEEC models. However, the
stability of these models is not guaranteed since so called
late-time instabilities may occur. We will give some insight into the
problem at hand and we will outline a pseudospectral technique
for observing the roots which are responsible for the
instabilities.
This is joint work with Jane Cullum.
