Automatic device driver synthesis is a radical approach to creating drivers faster and with fewer defects by generating them automatically based on hardware device specifications. I will present the design and implementation of a new driver synthesis toolkit, called Termite-2. Termite-2 is the first tool to combine the power of automation with the flexibility of conventional development. It is also the first practical synthesis tool based on abstraction refinement. Finally, it is the first synthesis tool to support automated debugging of input specifications. I will explain the main principles behind the tool and give a brief demo of its capabilities.
