General decoupled method for statistical interconnect simulation via polynomial chaos

This paper proposes a technique that allows to decouple the polynomial chaos equations for statistical interconnect analysis. The methodology is based on a transformation that renders the voltage and current polynomial chaos coefficients decoupled. Hence, these new decoupled coefficients are computed via repeated non-intrusive simulations. The advocated method maintains comparable accuracy with respect to the state-of-the-art approaches, nevertheless considerably easing the simulation procedure. Comparisons against literature results are provided to validate the proposed methodology.
