Original Kurzfassung:
Flow-based microfluidic biochips are attracting increasing attention with successful applications in biochemical experiments, point-of-care diagnosis, etc. Existing works in design automation consider the flow-layer design and control-layer design separately, lacking a global optimization and hence resulting in degraded routability and reliability. This paper presents a novel integrated physical co-design methodology, which seamlessly integrates the flow-layer and control-layer design stages. In the flow-layer design stage, a sequence-pair-based placement method is presented, which allows for an iterative placement refinement based on routing feedbacks. In the control-layer design stage, the minimum cost flow formulation is adopted to further improve the routability. Besides that, effective placement adjustment strategies are proposed to iteratively enhance the solution quality of the overall control-layer design. Experimental results show that compared with the existing work, the proposed design flow obtains an average reduction of 40.44% in flow-channel crossings, 31.95% in total chip area, and 22.02% in total flow-channel length. Moreover, all the valves are successfully routed in the control-layer design stage.
