“…Also, as part of any design process, one shall prepare Endof-Line (EOL) test specifications which will be used for inspection of units on production line. That, together with Hi-Pot test specification, DFMEA (Design Failure Mode and Effect Analysis) report, functional safety (FuSa) analysis [71], Hardware Automotive SPICE ® [81], [82], [83], technical cleanliness, and validation of power converters can be a topic of a future study.…”

In literature covering laboratories for switch-mode power supplies (SMPS) the focus was on university ones and learning outcome of their students. And there were almost no publications by authors from industry. Moreover, in a small number of older papers, description of the lab setup or equipment was provided. This paper addressed missing gaps by presenting an industrial laboratory for SMPS. Different aspects like lab structure, organization, procedures, equipment and software resources, calibration and safety, and typical standards used for hardware development, are covered comprehensively. The SMPS lab serves for development of dc-dc converters for commercial project(s) and for research. The developed dcdc converters are used as auxiliary power supplies (APS) of inductive charging systems. Additional investments in the lab, SMPS related, during period of 1.5 years, were paid-off quickly since the APS was project blocker. Side benefits and outcomes were created by publishing research papers that targeted industry and academia thus bridging the gap between the two. The publications increased company's visibility in academia, created an opportunity for a cooperation project, and served as partial documentation for engineers. It was also shown that investments in equipment and software are not enough. And that one has to invest in knowledge of engineers through buying books, attending seminars, visiting trade fairs, memberships, and subscriptions. Hence, notes on learning of power electronics were given too. Several results of applied research activities are presented to demonstrate lab capabilities. They were characterization of custom-designed magnetic parts at high operating temperatures for operating current range, and solutions for the APS with different flyback topologies. A comparison with few university labs revealed large difference in resources and outcomes in favor of the university ones. But differentiation of our industrial lab to them was covered as well.

“…Different norms check this traceability such as Automotive SPICE [ASPICE 2017] ASPICE 2017 2] and Automotive SPICE extension for Cybersecurity [ASPICE 2021], Functional Safety, and cybersecurity norms like ISO 21434 for proof of coverage of a cybersecurity case. Assessments are made to check this coverage and if the development process supports this ][Höhn 2015][Messnarz 2007][Messnarz 2009][Messnarz 2012][Schlager 2018][Wegner 2020].…”

The new generations of cars have a number of ECUs (Electronic Control Units) which are connected to a central gateway and need to pass cybersecurity integration tests to fulfil the homologation requirements of cars. Cars usually have a gateway server (few have additional domain servers) with Linux and a large number of ECUs which are real time control of actuators (ESP, EPS, ABS, etc. – usually they are multicore embedded controllers) connected by a real time automotive specific bus (CAN-FD) to the domain controller or gateway server. The norms (SAE J3061, ISO 21434) require cybersecurity related verification and validation. Fir the verification car manufacturers use a network test suite which runs > 2000 test cases and which have to be passed for homologation. These norms have impact on the way how car communication infrastructure is tested, and which cybersecurity attack patterns are checked before a road release of an ECU/car. This paper describes typical verification and validation approaches in modern vehicles and how such test cases are derived and developed.

“…Principle 'use dynamic and adaptable models as needed' Do integrate different norms into one V-model so that with one assessment and improvement all norms can be handled. [5][6][7][8][9][10]42,43 Do not create thousands of templates and one template per different norm, letting projects drown in formalism. Do define a structured portfolio of functions (see Figure 3) and map them to customer project releases.…”

The Verein der Deutschen Automobilindustrie (VDA) guidelines used for the interpretation of Automotive SPICE 3.1 contain many rules and recommendations and assessors apply them to check the consistency of ratings in an assessment. The VDA guidelines contain detailed procedures and templates to be used in planning, performing and reporting an assessment. However, an assessment is only a small part compared with the support and effort needed to implement improvements and to establish a company‐wide process improvement programme based on best practices. Whereas the VDA guidelines define the assessment process in detail, the ISO norm ISO/IEC 33014:2013 (Information technology—Process assessment—Guide for process improvement) defines a process improvement process. This paper analyses the ISO/IEC 33014:2013 norm and interprets it for the automotive sector and describes a state of the art improvement strategy typical of the automotive industry. Also, the SOQRATES group experiences about good and bad practices in implementing improvement programmes are shared and mapped onto the SPI manifesto principles. The paper concludes with a recommendation to add an improvement strategy‐related appendix to the VDA guidelines.
