Configurable Software Verification: Concretizing the Convergence of Model Checking and Program Analysis

Dirk Thilo Beyer, Grégory Théoduloz

In automatic software verification, we have observed a theoretical convergence of model checking and program analysis. In practice, however, model checkers are still mostly concerned with precision, e.g., the removal of spurious counterexamples; for this p ...

Path invariants

Dirk Thilo Beyer

The success of software verification depends on the ability to find a suitable abstraction of a program automatically. We propose a method for automated abstraction refinement which overcomes some limitations of current predicate discovery schemes. In curr ...

Runtime Checking for Separation Logic

Viktor Kuncak

Separation logic is a popular approach for specifying properties of recursive mutable data structures. Several existing systems verify a subclass of separation logic specifications using static analysis techniques. Checking data structure specifications du ...

A profiling framework for high level design space exploration for memory and system architectures

In 1971, the first microprocessor produced in mass production had 2300 transistor and was able to compute 60'000 operations per second at 740 kHz. Nowadays, even a common gaming console uses a central unit including 243 millions of transistors running at 4 ...

Path Invariants

Dirk Thilo Beyer, Andrey Rybalchenko

The success of software verification depends on the ability to find a suitable abstraction of a program automatically. We propose a new method for automated abstraction refinement, which overcomes the inherent limitations of predicate discovery schemes. In ...

Lazy Shape Analysis

Dirk Thilo Beyer, Grégory Théoduloz

Many software model checkers are based on predicate abstraction. If the verification goal depends on pointer structures, the approach does not work well, because it is difficult to find adequate predicate abstractions for the heap. In contrast, shape analy ...

Integrating Shape Analysis into the Model Checker BLAST

Dirk Thilo Beyer, Grégory Théoduloz

Many software model checkers are based on predicate abstraction. Values of variables in branching conditions are represented abstractly using predicates. The strength of this approach is its path-sensitive nature. However, if the control flow depends heavi ...

Foundations for SCALA

Vincent Cremet

SCALA is an attractive programming language because it is both very expressive and statically strongly typed. This marriage against nature comes at the price of a certain complexity in the language constructs and the static analysis. This complexity makes ...

OASIS - An ASIS Secondary Library for Analyzing Object-Oriented Ada Code

ASIS has proven to be an effective platform for developing various program analysis tools. However, in many cases ASIS, as defined in the ASIS ISO standard, appears to be at a very low-level of abstraction compared to the needs of the tool developer. Highe ...
