I3C Basic is a scaled-down and less complex version of the powerful, flexible and efficient I3C interface, suitable for a wide range of device connectivity applications, including sensor and memory interfaces. The I3C interface was developed by the MIPI Alliance and is designed to overcome the limitations of the I2C interface, while maintaining backward compatibility. Similar to I2C, devices on the I3C bus communicate in a controller/target environment, where both the controller and target device can initiate communication. In this project, the I3C target device used is the I3CS IP, which supports functions based on the MIPI I3C v.1.1.1. Due to the size and complexity of the project, functional verification becomes a challenge throughout the design flow.
