Digital microfluidic biochip is a revolutionizing plat-form to execute complex bioassay operations concurrently. De-pendability is an important feature of digital microfluidic biochipwhich is used for many safety-critical applications, such aspoint-of-care health assessment, air-quality monitoring, and food-safety testing. Therefore to ensure the proper functionality of thebiochip a robust offline and online testing is required. Testingcan be done before manufacturing or concurrently with otherbioassay operations. In this work, we are presenting an efficientparallel testing and diagnosis scheme to reveal the location ofall the faulty electrodes. Most of the algorithms present in theliterature are mainly focused on single fault identification. Butthe diagnosis of biochip with multiple faults is not addressedproperly. Even some of the algorithms have incorrectly classifiedthe non faulty electrode as a faulty electrode. Thus in thispaper, we are mainly focusing on the detection of multiple faults,correctly and efficiently. Moreover, this testing method is capableto check the given biochip with other concurrently runningbioassay operations.
