Verification of the Legacy Compatibility of the MIPI I3C Master

For decades now, an I2C technology has been an industry proven communication protocol in mobile and stationary devices. As the industry advances and the number of peripheral devices and data speeds rise, new protocols are being developed and implemented. The I3C is a backward-compatible successor to the I2C and achieves multiple gains in speed, operations and energy efficiency. A test method is developed to verify I3C Master parameters. The method can evaluate both, the new I3C and Legacy (I2C) signal parameters. The approach to the latter is presented in this paper.
