Universal Analyzer of Serial Buses
Gajdoš, Matúš ; Hanák, Pavel (oponent) ; Sysel, Petr (vedoucí práce)
The purpose of this master’s thesis is to design and to realize the universal analyzer of serial buses. At the beginning there are described in detail specifications and properties of buses IC, SMBus, PMBus and of the UART interface. The second part is targeted especially to design and to realize the control unit, which is the main part of the whole analyzer. It provides connecting to the unknown bus, to buses IC, SMBus, PMBus and SPI and to the UART interface. The main part of the control unit is the microcontroller PIC24HJ128GP204, which partially analyses connected bus. In the next part there is created the user application for PC, which controls and sets the control unit and receives from it partially analyzed data through the USB port. These data are used for the rest of the analysis that is done by the user application. Results may be presented to user in graphical or text form. The user application provides export of results into some of image formats. Supported formats are PS, SVG, PDF, PNG and BMP. In case of the control unit is not available, the user may choose the simulator to simulate some functions that the application provides. It supports simulation of the analysis of the unknown bus and the IC bus. The user application also contains the function of the generating own signals. Signals can be created interactively by using the mouse in the graphical representation of this signal. They can be sent to the control unit and after that it applies them to output. This function is not supported in current version of the control unit software. The user application includes some items, which do not have implemented any methods and they are prepared for the future upgrading of the analyzer. It means especially user controls and components for signal conversions between any buses.

Rozhraní typu I2C a jejich implementační možnosti v technologiích ASIC
Podzemný, Jakub ; Ambrož, Jaromír (oponent) ; Fujcik, Lukáš (vedoucí práce)
Práce se zabývá možnostmi implementace I2C, SMBus a PMBus rozhraní v současných technologiích ASIC. V první části se práce zaměřuje na popis jednotlivých sběrnic a jejich vzájemných rozdílů dle nejnovějších specifikací z digitálního a funkčního pohledu. Analogová část problematiky je zde z velké části zanedbána. Dále se práce zabývá porovnáním vybraných I2C/SMBus slave modulů vytvořených firmou ON Semiconductor, popsaných v jazyce Verilog HDL, z hlediska počtu klopných obvodů, funkčnosti a především vhodnosti pro jejich optimalizaci a rozšíření na PMBus slave modul. V poslední části se práce zabývá návrhem jednotlivých rozhraní na bázi I2C, tedy návrhem modulů I2C slave, SMBus slave a PMBus slave v jazyce Verilog HDL.
