BLAST: Berkeley Lazy Abstraction Software Verification Tool


BLAST is a software model checker for C programs.  The goal of BLAST is to be able to check that software satisfies behavioral properties of the interfaces it uses. BLAST uses counterexample-driven automatic abstraction refinement to construct an abstract model which is model checked for safety properties. The abstraction is constructed on-the-fly, and only to the required precision.
The first version of BLAST was developed at UC Berkeley by Ranjit Jhala, Rupak Majumdar, and Gregoire Sutre and was supported by the US National Science Foundation.

BLAST Documentation


Getting Started

 To get started with BLAST:
  1. Download and extract BLAST binaries and examples. To build BLAST from the sources, go to blast/ and run "make".
  2. Add the directory "blast/bin/" to your PATH environment variable.
  3. Go to "blast/test/" and run "./regrtest -block SHORT_REGRESS" to run the (small) examples in "blast/test".
  4. See the Tutorial Introduction section in the BLAST User's Manual to learn how to start with BLAST using the examples in "blast/test".
    The model-checking algorithm of BLAST is best explained in Section 2 of our journal paper on BLAST.

Experiments

The experiments page provides data on run time of BLAST on several open source programs and properties.
The applications page provides example programs that we have used for checking memory safety and generating test cases.
The lazy shape analysis page provides example programs that we have used for our experiments on lazy shape analysis.


People

BLAST is now developed at several universities.
  1. In Tom Henzinger's group at EPFL.
  2. In Ranjit Jhala's group at UC San Diego.
  3. In Rupak Majumdar's group at UC Los Angeles.
  4. In Dirk Beyer's group at Simon Fraser University.
Many people have contributed to BLAST, including Yvan Bidiville, Adam Chlipala, Jeff Fischer, Ken McMillan, Shaz Qadeer, Andrey Rybalchenko, Gregoire Sutre, Gregory Theoduloz, and Damien Zufferey.
