- October 24, 2007 Technical Report Software (Re-)Engineering with PSF III: an IDE for PSF, B. Diertens
We describe the design of an integrated development environment (IDE)
In the software engineering process we used process algebra in the form
of PSF for the specification of the architecture of the IDE.
This specification is refined to a PSF specification of the IDE system
as a ToolBus application, by applying vertical and horizontal
We implemented the various tools as specified and connected them with
a ToolBus script extracted from the system specification.
- November 30, 2006 Technical Report Software (Re-)Engineering with PSF II: from architecture to implementation, B. Diertens
This paper presents ongoing research on the application of PSF
in the field of software engineering and reengineering.
We build a new implementation for the simulator of the PSF Toolkit
starting from the specification in PSF of the architecture of a simple
simulator and extend it with features to obtain the architecture of
a full simulator.
We apply refining and constraining techniques
on the specification of the architecture to obtain a specification
low enough to build an implementation from.
- October 27, 2005 Technical Report Software (Re-)Engineering with PSF, B. Diertens
This paper investigates the usefulness of PSF in software engineering
PSF is based on ACP (Algebra of Communicating Processes) and
as some architectural description languages are based on process algebra,
we investigate whether PSF can be used at the software architecture level,
but we also use PSF at lower abstract levels.
As a case study we reengineer the compiler from the Toolkit of PSF.
