This course covers the Low Latency Interface (LLI) MIPI bus

Objectives The course starts with an overview of MIPI specification. The chapters are studied with a bottom-top approach, starting with M-PHY and ending with LLI. The electrical characteristics and related tests of the M-PHY layer are described. The course explains the M-PHY state machines and clarifies the configuration of M-PHY through attributes. LLI bridge from local interconnect to external M-PHY differential pairs is detailed. All layers of LLI from Physical Adapter to Transaction are explained through Service Access Points and Primitives. Companies interested in attending this course must adhere to MIPI organization. This course has been designed for engineers in charge of SoC architecture, functional verification or silicon validation. A more detailed course description is available on request at training@ac6-training.com
