PGY-UFS3.X-PA supports PWMG1 to HSG4B data rates and two TX, and two RX lane decode. The active probe has minimum electrical loading on the device under test (DUT) and captures protocol data without aﬀecting the performance of DUT. PGY-UFS3.X-PA Protocol Analyzer supports 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 of 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 the industry’s best protocol correlation between UFS to UniPro and MPHY layers. Time correlation between the different protocol layers significantly reduces debug time of designs. The floating window design of this software allows engineers to view the UFS view, UniPro view, and MPHY view on different computer monitors and automatically correlate the UFS packets to the MPHY layer. This makes analysis very easy while analyzing the gigabytes of Protocol information.

PGY-UFS3.X-PA UFS Protocol Analyzer provides USB 3.0 and Gbe interface for host computer connectivity. High-speed host connectivity enables continuous streaming of protocol data to host HDD and storage for a long period of time. The software offers multi-view such as MPHY view, UniPro view, and UFS View. Each view lists the respective protocol packets and their details with a correlation of each layer for easy debugging. The lightweight Analyzer is easy to carry during field visits.
Equalizer and Memory
PGY-UFS3.X provides the flexibility to 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. A newly introduced hardware-based circular buffer provides the flexibility to continuously capture the protocol data and analyze the data in circular buffer size. Users can set triggers on the circular buffer and capture the protocol data at specific events.
UFS Protocol Layer Decode
PGY-UFS3.X-PA Software can display each UFS packet parameter in a listing window. Right-click lists all the packet parameters for user selection. Users can color code the fonts or background color for easy identification of 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 links to UniPro packets. Users can view the MPHY states stall, prepare, and sync information in UniPro view apart from the 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 lists all the events. The list of events is 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 make it easy to view the data of interest
in the protocol listing window.
Comprehensive Protocol Analysis Using Multiview
PGY-UFS-PA UFS Protocol Analyzer provides USB 3.0 and Gbe interface for host computer connectivity. High-speed host connectivity enables continuous streaming of protocol data to host HDD and storage for a long period of time. The software offers multi-view such as MPHY view, UniPro view, and UFS View. Each view lists the respective protocol packets and their details with a correlation of each layer for easy debugging.
PGY Protocol Analyzer’s easy-to-use interface reduces the protocol analysis time. Time-stamped view of protocol decode listing provides an easy view of protocol activities between the host and the device. At a click of a button, the 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 debugging. Autocorrelation of each selected packet from UFS to MPHY layers simplifies the debug activity
Solder Down Probe Tips
Probing the UFS signal is one of the key challenges 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 types of 14 Gbps Probe tips which provide flexibility to choose the probe tips to meet the need. P5021-L and P5021-L-WE Probe tips have isolation resistors that can be changed based on the 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 the P5021 probe tip can be used to probe the test points.
