Abstract

Digital microfluidic biochips (DMBs) are microfluidic devices that manipulate droplets on an array of electrodes. Microfluidic operations, such as transport, mixing, and split, are performed on the electrode array to perform a biochemical application. All previous work assumes that the DMB architecture is given and most approaches consider a rectangular shape for the electrode array. However, nonrectangular application-specific architectures are common in practice. Hence, in this paper, we propose an approach to the synthesis of application-specific architectures, such that the cost of the architecture is minimized and the timing constraints of the biochemical application are satisfied. DMBs can be affected by permanent faults, which may lead to the failure of the biochemical application. Our approach introduces redundant electrodes to synthesize fault-tolerant architectures aiming at increasing the yield of DMBs. We have used a tabu search metaheuristic for this architecture synthesis problem. We have proposed a technique to evaluate the architecture alternatives visited during the search, in terms of their impact on the timing constraints of the application. The proposed architecture synthesis approach has been evaluated using several benchmarks.
