Magnetic angle position sensors have proved popular over the last decade. Because of their robustness they have prevailed as standard in a large variety of applications in the automotive, industry, consumer and medical area. Application examples in these areas include: throttle pedals, sewing machines, smartwatches and special surgery tools. Magnetic angle position sensors consist of an integrated circuit and a permanent magnet which serves as signal source and is attached to an object whose position needs to be sensed. The optimization of magnetic angle position sensors, in order to achieve high performance at low cost is complex. This thesis aims to solve these issues with a simulation-based approach. In general, the simulation of magnetic position sensors is complicated by several factors, therefore it requires expensive tools which are difficult to master and to use. These difficulties are overcome by a software called POS-Simulator. One part of the software is installed on the user's PC, which connects to a webserver where the other parts of the software are installed. All simulations are performed on the webserver. The simulation results are sent back to the user after the simulation has been completed. The simplicity of the POS-Simulator is attained by its high degree of specialization to the customer's needs. The POS-Simulator enables customers to design and verify the operation of position sensor systems within hours instead of several weeks. The simulation results have been verified by measurements where correlation with simulations was remarkably good. The accuracy of the simulation results is high enough to enable the optimization of applications and to predict their expected errors.
