A discontinuous Galerkin time-domain (DGTD) algorithm is proposed in this paper for transient thermal simulation of system integration. In order to reduce the complexity in the modeling of package structures, the equivalent thermal parameters of TSV interposer and bump layers are extracted properly. Then, by introducing the heat flux as an intermediate variable, the Laplace operator in the heat conduction...
Since accurate thermal analysis plays a critical role in the thermal design and management of the 3-D system-level integration, in this paper, a discontinuous Galerkin time-domain (DGTD) algorithm is proposed to achieve this purpose. Such as the parabolic partial differential equation (PDE), the transient thermal equation cannot be directly solved by the DGTD method. To address this issue, the heat...
