The Verified Software Challenge: A Call for a Holistic Approach to Reliability

  • Thomas Ball


The software analysis community has made a lot of progress in creating software tools for detecting defects and performing proofs of shallow properties of programs. We are witnessing the birth of a virtuous cycle between software tools and their consumers and I, for one, am very excited about this. We understand much better how to engineer program analyses to scale to large code bases and deal with the difficult problem of false errors and reducing their number. We understand better the tradeoffs in sound vs. unsound analyses. The software tools developed and applied over the last eight years have had impact. This list of tools includes Blast [HJMS02], CCured [NMW02], CQual [FTA02], ESC/Java [FLL + 02], ESP [DLS02], Feaver [Hol00], MAGIC [CCG + 04], MC [HCXE02], MOPS [CDW04], Prefast [LBD+04], Prefix [BPS00], SLAM [BR01], Splint [EL02] and Verisoft [God97], to name a few.

This bottom-up approach to improving code quality will continue to be successful because it deals with a concrete artifact (programs) that people produce, has great economic impact and longevity. Furthermore, because many of the tools listed above are specification-based, they are easy to extend to new classes of bugs. Finally, a lot of the science to support the development of these tools has been done; there is now before us a long road of engineering to make these tools truly useful and useable by a wide audience.
