Patent ID: 8539408

Claim:
A method for steady state and transient thermal simulation of a block-based structure or system comprising the acts of: selecting building blocks for a technology; performing a detailed numerical simulation of each selected block; constructing a reduced-order thermal model of each block using either one of the following techniques: (i) generating interior and boundary thermal modes of said reduced-order model from detailed numerical simulation data for each selected block and using interior and boundary thermal modes to enforce a coupling of modal solutions between said blocks; or (ii) generating thermal modes of said reduced-order model from detailed numerical simulation data for said entire domain of each selected block and using a discontinuous method to enforce a coupling of modal solutions between said blocks; storing thermal modes and model parameters of said constructed reduced-order thermal models for said selected building blocks in a library for said selected technology; constructing said reduced-order thermal model for said block-based structure from said generated thermal models for individual blocks in said library; wherein said acts perform a steady state and a transient thermal simulation of said structure; further wherein said thermal modes are basis functions of a function space; further wherein said thermal simulation is performed in said function space, where a temperature for each thermal mode in said function space is calculated; and further wherein said acts are performed using a computer.
