%X This paper describes the application of the Analytical
   Software Design methodology to the development of a
   mathematically verified I2C device driver for Linux. A model
   of an I2C controller from NXP is created, against which the
   driver component is modelled. From within the ASD tool the
   composition is checked for deadlock, livelock and
   other concurrency issues by generating CSP from the models
   and checking these models with the CSP model checker FDR.
   Subsequently C code is automatically generated which, when
   linked with a suitable Linux kernel run\-time, provides a
   complete defect\-free Linux device driver. The performance
   and footprint are comparable to handwritten code.
