Program update of Zynq-based devices
Michálek, Branislav ; Buchta, Petr (referee) ; Kubíček, Michal (advisor)
Among many which are placed on modern embedded systems is also the need of storing multiple system boot image versions and the ability to select from them upon boot time, depending on a function which they provide. This thesis describes the development of a system update application for Xilinx Zynq-7000 devices. The application includes a simple embedded HTTP server for a remote file transfer. A client is allowed to upload the boot image file with the system update from either command line application or using the web page developed for this purpose.

Model of MOSFET transistor in program SystemVision
Michálek, Branislav ; Brančík, Lubomír (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis deals with modeling of MOS transistor. The theoretical part of the thesis is dedicated to analysis of basic MOSFET structure and operation, basics of modeling in general, descriptions of SPICE models LEVEL1 and LEVEL3 and model parameters extraction by using the optimization technique. The realization part is dedicated to creation of static models for DC analysis for three specific MOS transistors in the form of netlist used in SPICE circuit simulators, using the model parameters, which have been obtained by using the optimization technique in Matlab. Validity of realized models is then verified by comparing of its characteristics, obtained from simulation in SystemVision program, with characteristics from transistor’s datasheets.
