MIPI LLI (M-PHY)
MIPI (Mobile Industry Processor Interface) serial buses are the backbone for communication in mobile products. The serial bus interface provides content-rich points for debug and test. However, since these protocols transfer bits serially, using a traditional oscilloscope has limitations. Manually converting captured 1’s and 0’s to protocol requires significant effort, can’t be done in real-time, and includes potential for human error. In addition, traditional scope triggers are not sufficient for specifying protocol-level conditions.
Extend your scope capability with Keysight Technologies, Inc. MIPI Low Latency Interface (LLI) triggering and decode application. This application makes it easy to debug and test designs that include MIPI LLI buses using your Infiniium Series oscilloscope.
The following are the MIPI LLI protocols and features that will be supported by the application.
MIPI LLI (M-PHY) Setup, Protocol Triggering, and Search Capabilities
Get access to a rich set of integrated protocol-level triggers. The application includes a suite of configurable protocol-level trigger conditions specific to MIPI LLI. When serial triggering is selected, the application uses software-based triggering.
With software-based protocol triggering, the oscilloscope takes signals acquired using either the scope or digital channels and reconstructs protocol frames after each acquisition. It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.
MIPI LLI (M-PHY) Protocol Decode
Get access to a rich set of integrated protocol-level triggers. The application includes a suite of configurable protocol-level trigger conditions specific to MIPI LLI. When serial triggering is selected, the application uses software-based triggering. With software-based protocol triggering, the oscilloscope takes signals acquired using scope channels and reconstructs protocol frames after each acquisition. It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.
Quickly move between physical and MIPI LLI protocol layer information using the time-correlated tracing marker. Display protocol content using embedded decode in the waveform area, or see protocol events in a compact listing format. Minor tick marks indicate clock transitions. Major tick marks indicate segments of the serial packet MIPI LLI measurements are automatically time-correlated with measurement on other scope channels.
Compact protocol using the full screen listing
The protocol viewer window shows the index number, time stamp value identifier, packet type, and data values for each MIPI LLI packet. Data in the listing window can be saved to a .csv or .txt file for offline.
MIPI LLI decode embedded in waveform area
Utilize the oscilloscope waveform area to display decode information. Minor ticks indicate clock transitions and major ticks show segments within each MIPI LLI packet.
