5.4 Chapter Summary and Conclusions
In this chapter, we have introduced the concept of design-for-testability for
microfluidic biochips. We have presented a test-aware design methodology
that allows the design of a pin-constrained biochip with 100% testability.
An Euler-path-based functional test method, which extends the applica-
tion of the functional test on irregular chip layouts, has also been presented.
The presented functional test method and the test-aware method have been
evaluated by applying them to design and test biochips for a multiplexed
bioassay and a PCR procedure. These DFT techniques form a bridge between
biochip design and testing. They not only allow the design of easy-to-test
biochip platforms but also broaden the application of the recently proposed
test methods to cover more generic chip layouts.
