Stochastic thermal simulation considering spatial correlated within-die process variations

Abstract: In this work, we develop a statistical thermal simulator including the effect of spatial correlation under withindie process variations. This method utilizes the Karhunen-Loève (KL) expansion to model the physical parameters, and apply the Polynomial Chaoses (PCs) and the stochastic Galerkin method to tackle stochastic heat transfer equations. We demonstrate the accuracy and efficiency of our simulator by comparing with the Monte Carlo simulation, and point out that the stochastic thermal analysis is essential… Show more

“…The description given above is delivered from any explicit formula of any particular process parameter. In contrast, the solutions from the literature related to Probability density Gaussian(0, 1) Beta (8, 8, −4, 4) Uncertain parameter Figure 5.3: Beta distribution fitted to the standard Gaussian distribution process variation are typically based on ad hoc expressions and should be individually tailored by the designer to each new parameter; see, for instance, [7,44,51]. The proposed framework provides great flexibility in this regard.…”

“…First, certain procedures cannot be undertaken without knowledge of time-dependent variations; one example of this is reliability optimization concerned with thermal-cycling fatigue, which is discussed in Section 3.6. Second, the static steady-state assumption that is considered, for instance, in [51,58,59,69] can rarely be justified, since power is not invariant in reality.…”
