UFS Protocol Analyzer (PGY-UFS3.X-PA)

UFS Protocol Analyzer (PGY-UFS3.X-PA)

UFS Protocol Analyzer(PGY-UFS3.X-PA) is the Protocol Analyzer with multiple features to capture and debug communication between host and design under test. PGY-UFS3.X-PA, UFS Protocol Analyzer, value based analyzer in its class, offers capture and debug of data across MPHY, UniPro and UFS protocol layers. It allows for instantaneous decoding of UFS layer, UniPro layer and MPHY layer with flexibility to correlate decoded data across these protocol layers.

PGY-UFS3.X-PA supports PWMG1 to HSG4B data rates and two TX, two RX lane decode. The active probe has minimum electrical loading on device under test (DUT) and captures protocol data without affecting the performance of DUT. PGY-UFS3.X-PA Protocol Analyzer support two lane data. Comprehensive decoding of UniPro & UFS data on the Fly enables validation of communication between UFS host and device.

PGY-UFS3.X-PA Protocol Analyzer allows Design and Test Engineers to obtain deep insight into UFS host and device communication. MPHY/UniPRO/UFS packet-based triggering allows specific protocol data capture and analysis. PGY-UFS Protocol analyzer instantaneously provides decoding of UFS, UniPro and MPHY layers with a correlation to MPHY, UniPro and UFS layers.

Solder down active probes allows probing the MPHY test points. This allows the design and test engineers to capture UFS traffic between the host and UFS memory with high signal fidelity. Today’s test engineers need to test the use case scenarios in their labs that mimic real-life use cases. The PGY-UFS3.X-PA, UFS Protocol Analyzer has been designed to enable engineers to closely monitor and analyze the traffic between the host and the device while executing the various use case scenarios.

Windows based protocol analysis software, provides industry best protocol correlation between UFS to UniPro and MPHY layers. Time correlation between the different protocol layers significantly reduces debug time of designs. Floating window design of this software allows engineers to view UFS view, UniPro view and MPHY view on different computer monitors and automatically correlate the UFS packets to MPHY layer. This makes analysis very easy while analyzing the gigabytes of Protocol information.

Test Setup

PGY-UFS3.X-PA UFS Protocol Analyzer provides USB3.0 and Gbe interface for host computer connectivity.High-speed host connectivity enables continuous streaming of protocol data to host HDD and storage for long period of time. Software offers multi-view such as MPHY view, UniPro view and UFS View. Each view lists the respective protocol packets and its details with correlation of each layer for easy debug. Lightweight Analyzer is easy to carry during field visit.

Equalizer and Memory

PGY-UFS3.X provides flexibility the set TX and RX CTLE and DFE equalizer to address reflection and poor SI signals while probing the MPHY signals. This helps in reducing the error decoding of packets. Newly introduced hardware based circular buffer provides the flexibility to continuously capture the protocol data and analyze the data in circular buffer size. User can set trigger on circular buffer and capture the protocol data at specific events.

UFS Protocol Layer Decode

PGY-UFS3.X-PA Software can display each UFS packet parameters in a listing window. Right click lists all the packet parameter for user selection. User can color code the fonts or background color for easy identification for each UFS packet.

PACP and UniPro View

PGY-UFS3.X-PA Software separates the PACP packets in a separate view for easy analysis of power mode change packets and link to UniPro packets. Users can view the MPHY states stall, prepare, sync information in UniPro view apart from user selection for L_Data and AFC/NACK Packet details.

Error Events, Search and Filter

PGY-UFS3.X-PA Software does the live decode and list all the events. The list of events are shown in this picture. Users can easily note the errors in captured protocol data. In large buffer capture, it takes extremely difficult to locate the errors. But PGY-UFS3.X-PA software simplifies this by listing events while decoding the captured data. Search and Filter allows you directly locate the error events or UFS or UniPro or PACP packet in the protocol listing windows. Filter-in and Filter-out makes it easy view the data of interest
in the protocol listing window.

Comprehensive Protocol Analysis Using Multi view

PGY-UFS-PA UFS Protocol Analyzer provides USB3.0 and Gbe interface for host computer connectivity. High-speed host connectivity enables continuous streaming of protocol data to host HDD and storage for long period of time. Software offers multi-view such as MPHY view, UniPro view and UFS View. Each view lists the respective protocol packets and its details with correlation of each layer for easy debug.

PGY Protocol Analyzer’s easy to use interface, reduces the protocol analysis time. Time stamped view of protocol decode listing provides easy view of protocol activities between host and the device. At a click of a button, user can view the decode of each packet and the intended function. Floating window software architecture allows the user to view each protocol layer on separate monitors for easy debug. Autocorrelation of each selected packet from UFS to MPHY layers simplifies the debug activity

Solder Down Probe Tips

Probing UFS signal is one of the key challenge in reliable UFS protocol decode. In most of the DUT, test points are located close to each other without enough space to solder the probe tips. Prodigy Technovations offers three type of 14 Gbps Probe tips which provides flexibility to choose the probe tips to meet the need. P5021-L and P5021-L-WE Probe tips has isolation resistor which can be changed based signal strength at test points. This helps in reducing reflections while accessing the test point and maintaining the signal integrity. The passive equalizer in P5021-L-WE helps in maintaining the differential impedance between the lane. If test points are easily accessible, then P5021 probe tip can be used to probe the test points.
