This quantity comprises the contributions offered on the foreign Workshop on present traits in utilized Formal equipment prepared October 7-9, 1998, in Boppard, Germany. the most target of the workshop was once to attract a map of the most important matters dealing with the sensible software of formal equipment in undefined. This seems to be really well timed with security and safety matters changing into a true hindrance to business software program and improvement. hence, just about all significant businesses have now arrange departments or teams to paintings with formal tools and plenty of ecu international locations face a critical labour scarcity during this new box. Tony Hoare's prediction of the artwork of software program (and undefined) improvement changing into a formal engineering technology with its personal physique of instruments and strategies is now changing into a truth. So the point of interest of this software orientated workshop was once now not loads on spe­ cial educational issues yet fairly at the many functional points of this rising new expertise: verification and validation, and gear aid and integration into the software program life-cycle. by means of comparing the cutting-edge with admire to commercial functions a dialogue emerged between scientists, practicing engi­ neers, and participants of regulatory and investment firms approximately destiny wishes and advancements. This dialogue result in roadmaps with appreciate to the way forward for this box, to device help, and capability program parts and promising industry segments. The contributions of the individuals from in addition to from the respective nationwide protection bureaus have been fairly important and hugely appreciated.

T h a n k s for the critical remarks received on drafts of this paper from Donatella Barnocchi, Don Batory, J o n a t h a n Bowen, Axel Dold, Mike Holcombe, J i m Huggins, Hans Langmaack, H a n n o Nickau, Peter Pappinghaus, Gerhard Schellhorn, Peter Schmitt, Wolfgang Schonfeld, Dilip Soni, Lothar Thiele, Kirsten Winter, Jeff Zucker. To Michel SintzofF thanks also for the stimulating discussion on the history of the concept of abstract machines. Last but not least thanks to my students in the Fall 1998 Specification Methods Course, in particular Marenco Yari, Fabrizio Sanna, Cristian Gozzi, Tommaso Mangini, Emanuele Lupi, Andrea Pieroni and Cinzia Ridolfo, for the ASM reuse experiments mentioned above.

The correctness proof for the first refinement step in the model for pipelining a RISC machine in [35] has been checked in KIV [67] and in PVS [124]; the proof checker applied in [79] has discovered an omission of a hazard case in the last refinement step. The properties proved for the production cell ASM [36] have been successfully model checked in [132]; this work is part of an effort to exploit the abstraction possibilities of ASMs to contain the state explosion problem when designing FSMs for model checking.

Stream X-machines are Mealy-ASMs where Rule is restricted as in X-machines, the o u t p u t is defined as concatenation of the current with the previous o u t p u t , and Cond(in) is restricted to a £ A for the underlying function alphabet A. T h e (stream) X-machines, in the form they are defined and used in [82,92, 83], are exposed to the difficulties of the frame problem. They inherit from their algebraic origin a global (Cartesian product) memory view, showing u p in the frequent " d o n ' t care" and " n o change" entries in function definitions.
