Processes for constructing safety-critical structures impose specified calls for on making sure necessities traceability. reaching useful traceability details, even though, is principally tricky about the transition from necessities to layout. Bernhard Turban analyzes platforms and software program engineering theories cross-cutting the problem (embedded structures improvement, platforms engineering, software program engineering, specifications engineering and administration, layout idea and approaches for safety-critical systems). As an answer, the writer proposes a brand new instrument method of help designers of their considering with a view to in achieving traceability as a spinoff to basic layout actions and to increase traceability details with information regarding layout selection rationale.

22 I. General Context and Theories new domain specific adoption Automotive SPICE (cf. [HDH+06]], [MHD+07]), or CMMI (Capability Maturity Model Integration, cf. [Kn06]). , fail safe modes, HW and SW redundancies) and increasing complexity put additional stress on the quality of development processes [BHM01]. Secondly, this implies that the worlds of the OEMs and the suppliers are in some way different and not completely comparable. Thus, problems may be different in both branches18. However, also the OEMs experience a paradigm shift towards intensified model-based development efforts [CFG+05], [KCF+04].
1). This is followed in ch. 2 by a general discussion about developing embedded systems in general. A certain category of embedded systems, called safety-critical embedded systems, demand special concerns about quality, because malfunctions in these systems can involve significant fatal consequences. Correspondingly, special standards for development processes (ch. 7) have evolved to ensure quality of the developed systems. One central demand are especially rigid demands for requirements traceability.
CFG+05] – interpreted by the author – describe that this model based shift consists of three cornerstones: • Usage of enhanced requirements engineering and management techniques. An experience report of Heumesser and Houdek [HH04] – from formerly Daimler Chrysler – mentions requirements specifications for the electronics of the whole system 'car' to contain about 20 000 pages, in which the requirements specifications for the single ECUs contain 200 to 600 pages. These high numbers of requirements must be adequately handled.
