Self-Testing of Microcontrollers
Denk, Filip ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This Master's thesis deals with functional safety of electronic systems. Specifically, it focuses on self-testing of the microprocessor and its peripherals at the software level. The main aim of the thesis is to design and implement a set of functions written in programming language C or assembly language, which automatically test the selected areas of the microcontroller. Resources and methods used in the implemented solution also aim to meet the requirements according to the safety standard IEC 60730-1, Annex H, Software Class B. The microcontroller NXP LPC55S69 was chosen as a hardware platform. It consists of two ARM Cortex-M33 cores. As a result, the example application is provided, which uses implemented test functions at the run-time. Example application also contains a graphical user interface with fault injection ability.

Functional Safety for Microcontrollers
Klecker, Jan ; Pavlík, Michal (referee) ; Hejátková, Edita (advisor)
This Master’s thesis deals with the principles and mechanisms of functional safety for microcontrollers. The IEC 60730 and IEC 60335 standards are described, from which the requirements for testing of microcontroller functional blocks are derived. Furthermore, the requirements for designing safety software are discussed. The most important chapter of the theoretical part is the design and discussion of functional safety tests for the given peripherals. In the practical part, a demo hardware of a gas boiler with safety features and diagnostic mechanisms controlled by two NXP KV46 microcontrollers communicating via a UART interface is designed. In the software chapter, the design of the application software for the gas boiler is described and then functional safety tests are implemented for the microcontrollers. For testing and demonstration purposes, a graphical user interface is designed in the FreeMASTER tool.
