Operational MOdel Order REduction for Nanoscale IC Electronics
Call Identifier: FP62005Mobility3
Simulation plays a major role in computer aided design of integrated circuits (ICs). Mathematical models describe the dynamical processes and interactions of electrical devices. Verification of a circuit's behaviour by means of solving these model equations in time and frequency domain is a mandatory task in the design process. The structures' sizes are decreasing, the packing density gets higher and so do the driving frequencies. This requires to use refined models and take into account secondary, parasitic effects. The very high dimensional problems that emerge in this way may be solvable with the help of computer algebra in an unreasonable amount of time only. Clearly, this conflicts with the short timetomarket demands in industry.
ModelOrderReduction presents a way out of this dilemma. Redundancies are resolved, less relevant quantities are replaced by the most significant ones. In this way, the problem's complexity is reduced, keeping the main characteristics. Solving lower dimensional problems one can get statements on the circuit's performance more quickly. Knowledge and experience in this field of computational science is scattered across european universities and companies.
In this three years' transferofknowledge (ToK) project, algorithmic knowledge from university is combined with application knowledge held at industry. In this way, theoretical approaches can be verified with real life problems from semiconductor industry. The industrial partner benefits from new ideas from academia. Furthermore, activities held at the universities provide an insight for new researchers to the tasks one is confronted with in the industry.
Four partners from industry and university work on different approaches for modelorderreduction, always trying to find synergies.
