Multiscale Universal Interface: A Concurrent Framework for Coupling Heterogeneous Solvers
Yu-Hang Tang, Shuhei Kudo, Xin Bian +2
Concurrently coupled numerical simulations using heterogeneous solvers are powerful tools for modeling multiscale phenomena. However, major modifications to existing codes are ofte…
Stochastic Testing Simulator for Integrated Circuits and MEMS: Hierarchical and Sparse Techniques
Zheng Zhang, Xiu Yang, Giovanni Marucci +5
Process variations are a major concern in today's chip design since they can significantly degrade chip performance. To predict such degradation, existing circuit and MEMS simulato…
Enabling High-Dimensional Hierarchical Uncertainty Quantification by ANOVA and Tensor-Train Decomposition
Zheng Zhang, Xiu Yang, Ivan V. Oseledets +2
Hierarchical uncertainty quantification can reduce the computational cost of stochastic circuit simulation by employing spectral methods at different levels. This paper presents an…
