Compilation et vérification de programmes LOTOS

Abstract : LOTOS (Language Of Temporal Ordering Specification) is a language for
the description of concurrent and communicating systems, standardized by ISO
and CCITT to allow formal definition of telecommunication protocols and
services. LOTOS is based on algebraic abstract types to specify data structures
and on a process calculus, close to CSP and CCS, to express control structures.

This thesis proposes a compiling technique which allows to translate
a significant subset of LOTOS into both interpreted Petri nets (which may
serve as a basis for executable code generation) and finite state automata
(which allow formal validation of LOTOS programs, either by reduction and
comparison according to equivalence relations, or by evaluation of temporal
logics formulas).

The method is different from existing approaches, based on term
rewriting, that directly build the state graph corresponding to a given LOTOS
program. Conversely, translation is achieved by three successive steps
(expansion, generation and simulation) dealing with intermediate semantic
models (namely SUBLOTOS language and networks).
It involves a static and global analysis of program behaviours. It can handle
data structures, that have to be compiled by already known algorithms.

These compiling principles are fully implemented in the software tool
CAESAR. Its demonstrated performances confirm the interest of the approach
