Among multiple synthesis stages of a digital microfluidic biochip, droplet routing which schedules the droplet movements in a time-multiplexed manner is a critical challenge due to the complex control constraints on different biochip architectures. We propose the first unified droplet manipulation algorithm to cope with the droplet manipulation problem on cross-referencing microfluidic biochips. Based on a novel graph model called cell-activation graph (CAG), the proposed method simultaneously performs droplet operations and droplet routing and guarantee the functional correctness of bioassays. It further improves the routing performance by 15% with only half of the runtime as compared with the state-of-the-art router. Experimental results on real-life benchmarks show that our algorithm achieves higher routability and scalability than previous droplet routing methods. |
