In the last 25 years, the notion of performing software verification with logic model checking techniques has evolved from intellectual curiosity to accepted technology with significant potential for broad practical application. In this paper we look back at the main steps in this evolution and illustrate how the challenges have changed over the years, as we sharpened our theories and tools. Next we discuss a typical challenge in software verification that we face today - and that perhaps we can look back on in another 25 years as having inspired the next logical step towards a broader integration of model checking into the software development process.
steady increase in computational power of general purpose computers, our ability to analyze routine software artifacts is also steadily increasing. As a result, we are witnessing a shift in emphasis from the verification of abstract hand-built models of code, towards the direct verification of implementation level code. This change in emphasis poses a new set of challenges in software verification. We explore some of them in this paper.
In this paper we explore a different approach to software verification. With this approach, a software application can be included, without substantial change, into a verification test-harness and then verified directly, while presearving the ability to apply data abstraction techniques. Only the test-harness is written in the language of the model checker.
