Latency-Optimization Synthesis with Module Selection for Digital Microfluidic Biochips

Digital microfluidic biochip (DMFB) is one of the latest developments in bioelectronics. It can replace traditional bulky equipment to facilitate biochemical assays and save the labor cost. Latency optimization is a common optimization objective of synthesis on DMFBs for assay time reduction. It is helpful for latency minimization if an operation can freely select one from a set of functional modules with various area-latency tradeoffs. In this paper, we propose an efficient latency-optimization synthesis algorithm with module selection capability, LOSMOS, for DMFBs. Experimental results show that LOSMOS outperforms several existing state-of-the-art synthesis algorithms and an ILP-based method without module selection.
