However, due to the increased demand for high quality and long-term reliable performance, techniques are focused to address placement for reliability. For instance, Huang and Fu [6] proposed a thermal force-directed algorithm based on a fuzzy model to manage the thermal placement problem of MCMs. Lee [7] developed a novel thermal force model based on a new force-directed algorithm and heat conduction analogy. This model is appropriate to solve the thermal placement problems of MCMs and hybrid circuits.
