MIPI Mobile Segment Protocol Decode Solutions Datasheet

Device driver ICs for peripherals like camera, display, memory, RF, and USB interface with application processors in mobile handsets - each of these interfaces has their own protocol to communicate to the application processor. System validation teams face constant challenges in terms of integration and validating communication between the devices. Tektronix provides a complete suite of these protocol decoders for M-PHY, D-PHY and various other interfaces in the mobile handset. The decoding solution helps designers efficiently and cost-effectively perform protocol validation in conjunction with electrical validation for MIPI specifications using a single oscilloscope.

The decoding solution offered has the ability to trigger on the signal of interest using hardware-based triggering and software-based triggering. The ability to use oscilloscope hardware triggers on live waveforms improves the accuracy of locking onto packet types of interest, search on different packet types and correlate with M-PHY electrical signals. Oscilloscope-based hardware triggering provides much higher accuracy than software triggers for capturing decoded signals. Hardware-based triggering is a unique capability offered by Tektronix for oscilloscope-based decoders. Various decoders are available and are listed below in detail.

Oscilloscope-based decode for M-PHY UniPro and LLI

M-PHY design and test engineers need to monitor and debug UniPro/LLI protocol interfaces to ensure reliable operation of the system. Manually interpreting the protocol layer information using oscilloscope data is time consuming and prone to human error in a versatile UniPro and LLI protocol standard.

PGY-UPRO and PGY-LLI Decode

The Prodigy PGY-UPRO/PGY-LLI Protocol Decode software offers extensive protocol decoding for M-PHY UniPro/LLI protocol specifications respectively. With this software, the M-PHY design and test engineers can now automatically make accurate and reliable decodes of multi-lane data, acquired by a Tektronix DPO/DSA/MSO70000 oscilloscope, and significantly reduce the development and test cycle.

The PGY-UPRO/PGY-LLI software automatically identifies all gears and signaling schemes such as NRZ and PWM, and decodes the protocol frames of multi-lane traffic. Built up on oscilloscope serial trigger features, the software computes CRC and verifies for CRC errors in a UniPro/LLI protocol packet. The software also links the decoded data to the electrical signal in the oscilloscope display, enabling better correlation from protocol- to physical-layer data. Furthermore, the software generates comprehensive and customizable reports, along with protocol data exportable in TXT and CSV formats. The software conforms to the M-PHY specification v1.0, the UniPro specification v1.4, and the LLI specification v0.8.

Oscilloscope-based decode for M-PHY 8b-10b

The SR-810B Serial Analysis application option enables Decode, Search, and Trigger on 8b/10b bus events for fast verification. All Tektronix MSO/DPO/DSA70000 Series oscilloscopes are equipped with a dedicated trigger chip for triggering on 8b/10b data patterns in high-speed serial signals up to 6.25 Gb/s. Installed as part of TekScope firmware, this software ensures finding even rare events. Furthermore, the DPO/DSA/MSO70000 Series oscilloscopes with PTD software support several 8b10b data values for triggering.

A very unique feature of the SR-810B option and perhaps the most powerful debugging tool is the capability to trigger on 8b/10b code errors. No serial trigger would be able to trigger on all possible character errors, disparity errors, or losses of byte synchronization, but the Tektronix 8b/10b serial trigger allows triggering on common errors such as disparity or character errors.

Report Generation

RF Front End control interface (RFFE) developed for controlling front interfaces including Power Amplifiers, Low-noise amplifiers, filters, switches, and power management modules in new generation mobile devices. Engineers designing RFFE interfaces need to test and debug the RFFE interface for its protocol specification. System designers need to debug the communication taking place in the RF interface. This process is time consuming and error prone, due to manually decoding the clk and data signals of RFFE for testing and debugging the hundreds of RFFE messages.
