UFS 4.0 Protocol Analyzer





PGY-UFS4.0-PA, UFS Protocol Analyzer is the industry-first working and tested UFS4.0 Protocol Analyzer. It offers protocol data capture and debugging of data across MPHY, UniPro, and UFS protocol layers. It allows for instantaneous decoding of UFS, UniPro, and MPHY layers with the flexibility to correlate decoded data across these protocol layers. PGY-UFS4.0-PA supports PWMG1 to HSG5B 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-UFS4.0- PA Protocol Analyzer supports two-lane data. Comprehensive on the fly decoding of UniPro & UFS data enables validation of communication between UFS host and device.

PGY-UFS4.0-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.

MDIO Protocol Exerciser and Analyzer Datasheet

Key features

Multi-Domain View

Multidomain View provides the complete view of MDIO Protocol activity in a single GUI. Users can easily set up the analyzer to generate MDIO traffic using a GUI or script. Users can capture Protocol activity at a specific event and decode the transition between Master and Slave. The decoded results can be viewed in the timing diagram and Protocol listing window with autocorrelation. This comprehensive view of information makes it the industry’s best, offering an easy-to-use solution to debug the MDIO protocol activity.


PGY-MDIO-EX-PD supports MDIO traffic generation using GUI and Script. Users can generate simple traffic generation using the GUI to test the DUT. Script-based GUI provides flexibility to emulate the complete expected traffic in the real world including error injections. In this sample script user can generate MDIO traffic as below:

Script line #1: Set system Frequency 25MHz, CLK to DATA delay to 0ns, Duty cycle 50%, System inter message gap to 0us
Script line #3: WRITE
Script line #4: WRITE
Script line #5: READ
Script line #6: READ
Script line #7: WRITE

Timing Diagram and Protocol Listing View

The timing view provides the plot of MDC and MDIO signals with a bus diagram. Overlaying of Protocol bits on the digital timing waveform will help easy debugging of Protocol decoded data. Cursor and Zoom features will make it convenient to analyze Protocol in the timing diagram for any timings errors.

The protocol window provides the decoded packet information in each state and all packet details with error info in the packet. The selected frame in the Protocol listing window will be autocorrelated in the timing view to view the timing information of the packet.

Key Specifications

Setup View

PGY-MDIO-EX-PD supports both Clause 22 and Clause 45. Users can set this in the setup view according to their preference.
