Universal Analyzer of Serial Buses
Gajdoš, Matúš ; Hanák, Pavel (referee) ; Sysel, Petr (advisor)
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.

I2C-Based Interfaces and Their Implementation Possibilities in Current ASIC Technologies
Podzemný, Jakub ; Ambrož, Jaromír (referee) ; Fujcik, Lukáš (advisor)
This work deals with implementation possibilities of I2C, SMBus and PMBus interfaces in current ASIC technologies. In first part of this work are descriptions of these interfaces considering their actual specifications and differences between them from digital and functional point of view. The analog part of this issue is for the most part ignored. Additional part is focused on comparison of selected Verilog HDL I2C/SMBus slave modules developed by ON Semiconductor company by size, function and mainly by optimization and extension possibilities. Last part of this work deals with newly designed I2C-based interfaces. New I2C slave, SMBus and PMBus slave modules are described in Verilog HDL language.
