Nanoelectronic COupled Problems Solutions (nanoCOPS)

Designs in nanoelectronics often lead to large-size simulation problems and include strong feedback couplings. Industry demands the provision of variability to guarantee quality and yield. It also requires the incorporation of higher abstraction levels to allow for system simulation in order to shorten the design cycles, while at the same time preserving accuracy. The nanoCOPS project addresses the simulation of two technically and commercially important problem classes identified by our industrial partners: -- Power-MOS devices, with applications in energy harvesting, that involve couplings between electromagnetics (EM), heat, and stress, and -- RF-circuitry in wireless communication, which involves EM-circuit-heat coupling and multirate behaviour, together with analogue-digital signals. To meet market demands, the scientific challengs are to: -- create efficient and robust simulation techniques for strongly coupled systems that exploit the different dynamics of sub-systems and that allow designers to predict reliability and ageing; -- include a variability capability such that robust design and optimization, worst case analysis, and yield estimation with timy faliures are possible (including large deviations like 6-sigma); -- reduce the complexity of the sub-systems while ensuring that the parameters can still be varied and that the reduced models offer higher abstraction models that are efficient to simulate. Our solutions are -- to develop advanced co-simulation/multirate/monolithic techniques, combined with envelope/wavelet approaches; -- to produce new generalized techniques from Uncertainty Quantification (UQ) for coupled problems tuned to the statistical demands from manufacturability; -- to develop enhanced, parametrized Model Order Reduction techniqes for coupled problems and for UQ.
