Summary:This paper presents a Laguerre-based discontinuous Galerkin time domain (LBDGTD) method for transient thermal simulation of 2.5-D integrated systems. The proposed method eliminates the time variable by employing weighted Laguerre polynomials as the temporal basis functions. With the Galerkin temporal test procedure, a set of recursive linear equations is derived. This algorithm inherits the element-level domain decomposition property from discontinuous Galerkin time domain (DGTD) method. Furthermore, as a march-on-in-order algorithm, LBDGTD is not subject to the restrictions imposed by the Courant-Friedrichs-Lewy (CFL) condition. A numerical example verifies the precision and efficiency of the LBDGTD.
