Digital microfluidic biochip is a promising alternative to the traditional cumbersome laboratory equipment. Such automated biochips are used in many critical applications. Hence dependability is an essential attribute before the chip is in use. Due to mixed integration technologies, these chips have some unique failures. Hence robust offline and online tests are proposed to check the health of the biochips. When a chip undergoes a test in offline mode, then the entire biochip should be available for testing, whereas for the online mode test droplet might be stalled due to unavailability of the next cell in the routing path. However, in both the scenarios one or more droplets route across the chip and the arrival time is also recorded at the destination. So here we have proposed two test schemes to know the correctness of any biochip. Diagnosability is an important feature to find the exact position of the faulty electrode. Our proposed scheme reduces the overall testing and diagnosis time significantly. It also provides an alternative routing path in biochip for fault tolerance.

数字微流控生物芯片是传统繁琐实验室设备的有前途的替代品。这样的自动化生物芯片被用于许多关键应用中。因此，在使用芯片之前，可靠性是必不可少的属性。由于混合集成技术，这些芯片有一些独特的故障。因此，提出了健壮的离线和在线测试来检查生物芯片的健康状况。当芯片在离线模式下进行测试时，整个生物芯片应可用于测试，而对于在线模式，由于路由路径中下一个单元的不可用，测试液滴可能会停滞。但是，在这两种情况下，一个或多个小滴都会穿过芯片，并且到达时间也会记录在目的地。因此，在这里我们提出了两种测试方案来了解任何生物芯片的正确性。可诊断性是找到故障电极准确位置的重要功能。我们提出的方案显着减少了整体测试和诊断时间。它还为生物芯片中的容错提供了另一种路由路径。
