Formal Functional Verification of Device Drivers

  title={Formal Functional Verification of Device Drivers},
  author={Eyad Alkassar and Mark A. Hillebrand},
We report on the formal functional verification of a simple device driver for an ATAPI hard disk in Isabelle/HOL. The proof is based on a functional model of the hard disk, which has been integrated into the instruction set architecture of a verified RISC processor as one of several memory-mapped devices. The result is an interleaved computational model, in which the devices and the processor take turns in execution. Even in this concurrent context, the verification can be kept largely… CONTINUE READING
