Carrying out a data- and control flow analysis is required in almost all functional safety standards (ISO 26262-6 Table 7 Measures 1f/g, DO 178C Table A-7 Measure 8 and EN 50128, EN 50657Table A19 Measures3/4). In comparison to other measures, the data and control flow analysis causes a lot of questions, when it comes to the real execution. This is mainly since the technological capabilities have so far been lacking to carry out such an analysis.
The new non-intrusive system observation technology (www.accemic.de) offers the possibility to prove data- and control flows by tests. Therefore, a systematic check can be performed in future to prove the functional completeness of the requirements. Read more
