Ty. Chou et Zj. Cendes, CAPACITANCE CALCULATION OF IC PACKAGES USING THE FINITE-ELEMENT METHOD AND PLANES OF SYMMETRY, IEEE transactions on computer-aided design of integrated circuits and systems, 13(9), 1994, pp. 1159-1166
Finite element techniques are presented for determining the capacitanc
e of three-dimensional interconnection structures. Results are present
ed for two typical intergrated circuits packages: the plastic leaded c
hip carrier (PLCC) and the dual in-line package (DIP). The symmetry of
the capacitance matrix in the package is described and a set of formu
las is presented to take advantage of this symmetry in capacitance cal
culation. This leads to the reduction in cpu time and memory usage and
better converged solution.
