D9010MPMP

MIPI M-PHY Protocol Trigger and Decode Package for Infiniium Oscilloscopes

Introduction

The D9010MPMP software package for Infiniium oscilloscopes gives you the ability to trigger and decode various MIPI® M-PHY® based protocols, such as CSI-3®, DigRFSM, LLISM, USB 3.0 SSIC, UFS, and UniPro®. This package applies to all Infiniium Oscilloscopes.

Product Overview

MIPI (Mobile Industry Processor Interface) serial buses are the backbone for communication in mobile products. The serial bus interface provides content-rich points for debugging and testing. 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. As well, traditional scope triggers are not sufficient for specifying protocol-level conditions. Extend your scope capability with the Keysight Technologies, Inc. D9010MPMP MIPI M-PHY triggering and decoding application. This application makes it easy to debug and test designs that include DigRF, LLI, CSI-3, UniPro, UFS, and SSIC buses using your Infiniium Series oscilloscope. The benefit of an oscilloscope with MIPI decoding is viewing the physical layer and protocol layer simultaneously. Timecorrelated views help quickly troubleshoot serial protocol problems back to their timing or signal integrity root cause. Viewing decoded information on up to four live or saved waveforms couldn’t be simpler – just use Infiniium’s Auto Setup (Figure 1).

Quickly move between physical and protocol layer information using the time-correlated tracing marker (Figure 2). 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. Measurements are automatically time-correlated with measurements on other scope channels. The protocol viewer window shows the index number, time stamp value identifier, packet type, and data values for each packet. Data in the listing window can be saved to a .csv or .txt file for offline. D9010MPMP also provides access to a rich set of integrated protocol-level triggers. The application includes a suite of configurable protocol-level trigger conditions specific to MIPI M-PHY buses. 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 protocollevel trigger conditions and triggers when the condition is met.

DigRF v4 (M-PHY)

Keysight MIPI DigRF v4 (M-PHY) protocol decode software supports SYS-BURST mode decode along with HS-BURST (high-speed) mode. Keysight MIPI DigRF v4 (M-PHY) protocol decoder software supports both high-speed (HS-BURST) and low-speed (SYS-BURST) modes on Tx and Rx packets. Also, it supports decodes with or without cyclical redundancy check (CRC) support.

LLI (Low Latency Interface)

D9010MPMP supports LLI v1.0 and v2.1 decode and triggering, high-speed (HS-BURST) and low-speed Pulse Width Modulation (PWM-BURST) decoding, decode on Tx and Rx traffic, and search capability for various frames, sequences and errors.

CSI-3 (Camera Serial Interface 3)

Camera Serial Interface version 3.0 (CSI-3) standard was developed by MIPI Alliance to increase performance throughput and greater feature set from CSI-2 standard. The CSI-3 interface runs on top of the MIPI M-PHY electrical layer as well as the MIPI UniPro protocol layer that is also developed by MIPI Alliance standard body. D9010MPMP supports CSI-3 v1.0 decode and triggering, and it can be used together with the MIPI UniPro protocol decode to show both CSI-3 and UniPro packets at once. It can also decode High-Speed (HS-BURST) and Low-Speed Pulse Width Modulation (PWM-BURST) modes and supports search capability for Host and Device transactions as well as symbol sequence and errors.
