a model checker for programs
dSPIN is an extension of the SPIN
model checker that offers efficient means for the verification of concurrent
programs written in high(er)-level programming languages. It provides a
number of novel features implemented on top of standard SPIN's state space
exploration and reduction algorithms:
The design of dSPIN is driven by the need
to enhance the expressiveness of existing modeling techniques, while coping
with potential complexity blow-ups caused by adding extra functionalities.
The input language of dSPIN is a superset of PROMELA containing a small
number of new constructs such as pointer type variables, memory allocation
statements, function definitions and invocations. Such constructs are supported
by both the random simulator and verifier generator. The tool is SPIN-backwards
compatible that is, every standard SPIN model can be also verified using
memory references (pointers);
dynamic memory allocation/deletion;
function code references (function pointers)
