The objective of this project is to design and implement a reliable and efficient **SPI to I2C protocol conversion module using Verilog HDL**, enabling seamless communication between devices operating on different serial protocols. The work aims to understand and bridge the functional differences between SPI and I2C by developing a protocol converter that correctly handles data formatting, clock synchronization, control signaling, and timing requirements. The design is implemented, simulated, and verified to ensure correct data transfer, low latency, and robustness, making it suitable for embedded systems and SoC applications where interoperability between SPI- and I2C-based peripherals is required.
