A Multi-Objective-Driven Placement Technique for Digital Microfluidic Biochips

Abstract

Microfluidic biochips are extensively utilized in biochemistry procedures due to their low cost, high precision and efficiency when compared to traditional laboratory procedures. Recent, computer-aided design (CAD) techniques enable a high performance in digital microfluidic biochip design. A key part in digital microfluidic biochip CAD design is the biochip placement procedure which determines the physical location for biological reactions during the physical design. For the biochip physical design, multiple objects need to be considered, such as the size of the chip and the total operation time. In this paper, a multi-objective optimization is proposed based on Markov decision processes (MDPs). The proposed method is evaluated on a set of standard biochip benchmarks. Compared to existing works, experimental results show that the total operation time, the capacity for routing and the chip size can be optimized simultaneously.
