Experience

Digital Oscilloscope Development

I developed the firmware for an FPGA-based digital oscilloscope, using Verilog in Vivado to implement real-time signal acquisition and processing. The project required designing a high-speed system to capture and analyze multiple signal channels with minimal latency. I implemented custom DSP algorithms directly on the FPGA, including filtering and noise reduction, to ensure precise and accurate signal representation.

Additionally, I integrated Block RAM and FIFO buffers, optimizing the system for efficient data storage and processing of large volumes of high-frequency data. Leveraging pipelining techniques, I ensured smooth data flow, achieving a latency of less than 10 nanoseconds per channel. I also incorporated advanced debugging and testing frameworks to verify system performance, enabling seamless integration with ADCs and external communication interfaces.

Throughout the project, I extensively documented the design and testing processes, creating detailed user manuals and design specifications for future maintenance and enhancements. This project required close collaboration with hardware and software teams to ensure seamless hardware-software co-design, resulting in a reliable and high-performance digital oscilloscope.
