This paper presents the expendable multi-language analysis and verication system
SPECTRUM, which is being developed within the framework of the project SPEC-
TRUM. The project prospects are discussed using the example of C program verication.
The project aims at the development of a new integrated approach to program verica-
tion which will allow the integration, unication and combination of program verication
techniques together with accumulation and reuse of knowledge about them. One of the
project features consists in the use of the specialized executable specication language
Atoment. This language provides a unied format to represent both verication meth-
ods and data for them (program models, annotations, logic formulas). The C-targeted
component of the SPECTRUM system is based on our two-level C program verication
method. This method represents a good illustration of the integrated approach, since
it provides a complex C program verication that combines operational, axiomatic and
transformational approaches
