Physical defects in digital microfludics chips (DMCs) can be very complicated and extremely difficult to find precise models, because each defect may occur anywhere. In this thesis, we develop high-level abstract fault models based on investigating the faulty and fault-free behaviors of droplet moving. Two new fault models that were not found previously are proposed to enhance the reliability of DMCs. We believe that the high-level fault models can completely cover all defects involving two cells in a DMC array. Based on the new high-level fault models, we propose march algorithms (march-d and march-p/p+) to generate test patterns that can detect and distinguish fault types for each faulty digital microfludics chip. This is accomplished by merging both march-d and part of march-p without causing too much test length increase. These algorithms are implemented into a FPGA board attached to the simulated digital microfluidics chip such that built-in self-test can be accomplished without human intervention. We also develop an EDA tool and simulation platform for the proposed DMC-BIST system. Experimental results demonstrate that the proposed fault models, test and fault type distinguishing methods, built-in self-test circuit design, and emulation tool can effectively and efficiently achieve high quality test with minimal test cost.
