I3C Triple Check Development

Abstract

The rapidly increasing number of sensors creates new design challenges for mobile, automotive, and Internet of Things (IoT) devices. These challenges include significantly higher overall pin count and increased bandwidth requirements. To address these challenges the MIPI Alliance has defined the I3C interface for connecting all sensors in the system with a single 2-wire high speed connection. Compliant with the MIPI I3C and compatible with legacy I2C specification, the Cadence IP for MIPI I3C master controller is engineered to quickly and easily integrate into any mobile embedded System on Chip (SoC) device and expand sensor communication capabilities with better performance and power efficiency. In this project, Triple Check IP Validator helps IP developers to verify that their designs meet all the required specifications that define standard interfaces. It simplifies and accelerates compliance testing and interfaces verification by providing the three things that verification engineers need most which are: Test Suits, Coverage Model and Verification Plan. By developing various test cases to test the specifications and functionality of Design Under Test (DUT) and by observing resulted wave forms and checker files data one can resolve the issue by making some required changes if any error or protocol violation is occurred. VIP should include functional coverage metrics to ensure that all corner cases of the protocol have been verified. Here an I3C VIP with coverage points enumerates all the different ways of completing a transaction. Covering these points ensures that important protocol functionality has been verified. If any of these points is not covered, verification is incomplete. By observing cover group analysis, one can estimate if any test case or specification is not covered and make necessary changes. In this project the goal is to give functional coverage of VIP more than 95 percent as it is very important to give a well tested VIP to costumers.
