dc.description.abstract Data converters are used in mixed-signal designs and are important electronic devices with applications in many areas like consumer electronics, communications, computing, control and instrumentation. Design of these data converters to high performance is a challenging task whereas testing of these data converters for correct functionality has also got equal importance. The aim of this thesis is to develop a method for testing data converters using Verilog HDL code and to implement a platform design on a FPGA board. This platform uses the Fast Fourier Transforms as a spectral analysis method for determining the dynamic performance of data converters and associated logic. A focus of attention is to understand the fundamentals of digital signal processing and digital design using good Verilog HDL coding practice. This is achieved through the design and application of a 7-tap FIR filter both in MATLAB and Verilog RTL. This design system is achieved by developing an FPGA test platform using a Xilinx Zynq board FPGA which supports a 1M Sample ADC along with an Analog Mixed Signal card containing external Digital to Analog converters for signal generation. The FPGA supports a sine wave generator that uses sine wave signals as test vectors that are fed to DAC so that an analogue signal is provided to the ADC. The output samples are sampled by the ADC and stored in memory that is then accessed through a serial to parallel interface for spectral analysis in MATLAB. This design is furthered with development of a potential application where the ADC outputs are applied to Finite Impulse Response filters for further analysis. The final results of this thesis include FFT plots and also simulated timing diagrams. en_US
