| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. FDR
(Failures-Divergences Refinement) and subsequently FDR2 are refinement
checking software tools, designed to check formal models expressed in
Communicating sequential processes (CSP). The tools have been developed
by Formal Systems (Europe) Ltd. Bill Roscoe of the Oxford University
Computing Laboratory devised the algorithms used by the tool and Michael
Goldsmith was instrumental in the implementation. FDR2 is downloadable
from Formal Systems. FDR2 is a commercial product of Formal Systems
(Europe) Ltd. It is often described as a model checker, but is
technically a refinement checker, in that it converts two CSP process
expressions into Labelled Transition Systems (LTSs), and then determines
whether one of the processes is a refinement of the other within some
specified semantic model (traces, failures, or failures/divergence). |
