Application of Model-Based Systems Engineering in Complex System Development: a Power Management IC case study

This thesis explores the use of Model-Based System Engineering (MBSE) in the design and development of Power Management Integrated Circuits. PMICs are critical components in modern electronic systems, responsible for managing and regulating power supply to various components of a system; the use of MBSE can greatly improve the efficiency and reliability of systems design, by providing a systematic and hierarchical approach to the development and description of the system. The thesis work begins with a study of the principles and advantages of MBSE, followed by a detailed overview of sysML, the model description language chosen for the project, intending to be a preliminary approach to SysML and Enteprise Architect modeling tool for the reader. Proceeding further, the case study is presented, where MBSE is applied to the design of a first set of modules of PMIC, demonstrating the effectiveness of this technique and the quality of the final design, including the set of simulations performed on the model and final results.
