This thesis presents a power simulation of a MIPS MicroAptiv UP Core implemented as
a virtual ASIC prototype using Taiwan Semiconductor Manufacturing Company(TSMC)
65 nm CMOS technology. Based on the MIPS instruction set program data is generated
and introduced in the simulation by means of initialization files. Before the simulation,
technology specific SRAM modules are integrated into theMIPS core. Two different programs
are used for power characterization. The first program performs frequent memory
accesses by means of load/store word instructions, while the second program is a loop
which operates on registers only and mainly increments addresses. The simulation is
based on a virtual prototype which is generated by synthesis and place & route including
post-layout parasitic extractions. The stimuli for the power extraction is generated
via gate-level simulation and forwarded to the power calculation engine. The effect of X-propagation
on gate-level simulations is avoided by modifying the address-related statements
in the execution data path module, which use another form of 2 to 1 multiplexer,
setting the output to zero for all input signals even with an initial value of ’x’ without
changing the functionality. Finally, the consumed power is provided by reports generated
by the power simulation engine. The memory-centric program consumes 35.39mW
of internal power using instructions, which is 0.73mW less than the internal power of the
register-centric program, and the overall average power is also lower by almost 0.7mW.
In this thesis, the radiation sensitivity of the novel Cologne Chip GateMate A1 field-programmable gate array (FPGA) is evaluated. An initial introduction of radiation mechanisms and their effects on electronics is given, followed by a brief overview of radiation test standards. The common elements present in FPGAs are discussed, which is followed by details of the GateMate FPGA device and a description of the software design flow. Afterwards, the development of a purpose-built printed circuit board (PCB) for radiation tests with the GateMate FPGA is detailed.
Four components of the GateMate have been tested during three radiation campaigns, as well as a benchmark circuit to compare the radiation performance of the GateMate with other FPGAs tested at the European Organization for Nuclear Research (CERN). The test architecture consists of the device under test (DUT) FPGA and a TESTER FPGA whose task is to provide inputs to the DUT and record its response. The DUT and TESTER designs developed for all tests are discussed in detail. Finally, the results obtained during the irradiation campaigns are presented, showing that the GateMate FPGA performs similarly to other FPGAs using the same process technology. Only the benchmark test was not finalized, as implementation problems prevented its completion in the given time frame. The thesis concludes with a comprehensive summary and outlook.
The work presented in this thesis deals with the distance measurement aspect of a 3D Polarization ToF camera for automotive applications that uses a Time-to-Digital Converter (TDC) to measure the time interval between the emission of light from a source and its reception. Based on the measurement of the time interval, distance can be calculated by applying the equation of motion. In application, achieving an exact distance measurement is quite strenuous because the operating conditions of the design are susceptible to change due to environmental factors. Therefore, to achieve accuracy in distance measurement, the time interval between the emission and reception of light must be measured precisely. For this purpose, a delay asymmetry compensation logic is developed. This thesis elaborates the addition of debugging features, redesign of some components, digital calibration approach and the entire testbench environment of the delay asymmetry compensation logic. It also sheds light on the implementation of the designed logic for its successful realisation in real hardware. Lastly, it concludes by narrating future prospects and further scopes of development.
Growing demand for security in a wide range of fields gives raise to research for more efficient and modern methods. Additionally, the increase of systems that are deployed on hardware requires security to be embedded in small area to protect intellectual property, hardware, and integrity and confidentially of sensible data. Therefore, in this work a design and FPGA implementation of a highly resource-efficient AES-256 encryption and decryption engine is presented, as well as its comparison with state-of-the-art designs. The design shows a reduction in the resources used due to its architecture to reuse hardware throughout all the processing. The design is implemented on a Xilinx Artix-7 FPGA.
The aim of this master thesis is the design and implementation of mixed-signal
processing chain for the optical determination of rotation angles by means of four
sensors implemented as photodiodes with integrated polarization filters and a
high-precision CORDIC hardware design implemented on an FPGA in Verilog.
Furthermore, a light source and a polarizer are integrated in the measurement
setup which is configured using an QT application.
This thesis discusses the development of test environments using Xilinx Zynq System on Chip (SoC) for measuring leakage currents and radiation qualification of Static Random Access Memory (SRAM) based Field Programmable Gate Arrays (FPGAs) at European Organisation for Nuclear Research (CERN). The effects of radiation on electronic components are explained, followed by an introduction to the FPGAs used.
The GateMate FPGAs leakage current is measured in its application area with respect
to temperature and core voltages. A comparable testing environment is used from the
tester to the tested device, as it will later be used at CERN. The GateMate is being
prepared in this setup for the finalization of radiation qualification at CERN, to be
transferred later. For this purpose, the basic tests are explained and the outstanding
tests are then carried out. The Lattice iCE40 UltraLite FPGA is used in an initial
application test to determine its suitability for further radiation qualification tests at CERN. The analysis and presentation of the test results are followed by a summary and outlook.
