FPGA based remote programmable and monitorable circuit board design and application

FPGA (Field Programmable Gate Array) chips offer advantages such as high performance, parallel processing capability, and low power consumption. Due to these features, they are widely used in fields such as defense, artificial intelligence, medical electronics, and communications. However, dependence on high-cost foreign hardware that does not always meet specific requirements remains a challenge. The development of domestic and customizable FPGA boards has thus become a critical necessity to provide both flexibility and cost efficiency. In this thesis study, a remotely programmable and observable FPGA development board has been designed. The design incorporates the Xilinx XC3S50AN FPGA chip and the ESP32 microcontroller. The ESP32 controls the FPGA chip through reset, trigger, and 4-bit data signals. The web interface has been developed using HTML (HyperText Markup Language) and JavaScript. Users can monitor the circuit via a live streaming panel. Additionally, they can download compiled projects from the code panel or send them via email, with the designed UCF (User Constraints File) content included in the email. Furthermore, bit files can be uploaded through Google Drive, and a Python script detects these files and programs the FPGA chip via JTAG (Joint Test Action Group), completing the programming process in an average of 7.579 seconds. vi In this study, various applications such as LED (Light Emitting Diode) control, half adder, full adder, mod-4 counter, up-down counter with a 7-segment display, and bit shifter have been successfully tested. The system ensures secure usage with different authorization levels for Administrator, Laboratory, and User access. This study successfully implements an FPGA-based remotely controlled laboratory application, providing a viable alternative to high-cost imported FPGA development boards. The developed domestic FPGA development board enables programmability and real-time observation of design outputs, contributing to more flexible and cost-effective FPGA applications.
