UFS Protocol Software
PGY-UFS4.0-PA, UFS Protocol Analyzer is the industry first working and tested UFS4.0 Protocol Analyzer. It offers protocol data capture and debug of data across MPHY, UniPro and UFS protocol layers. It allows for instantaneous decoding of UFS, UniPro and MPHY layers with flexibility to correlate decoded data across these protocol layers. PGY-UFS4.0-PA supports PWMG1 to HSG5B 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-UFS4.0- PA Protocol Analyzer support 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.
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- UFS4.0-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.
Test Setup
PGY-UFS 4.0-PA UFS Protocol Analyzer interfaces to solder down probe tips using mSMP Flexi coax cables. The active probe tips are powered by a power module which is powered by PGY-UFS4.0-PA. Protocol Analyzer is interfaced to host computer using USB3.0 interface. High-speed host connectivity and 16GB buffer enable continuous streaming of protocol data to host SSD and storage for a longer 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.
UFS Protocol Layer
PGY-UFS 4.0-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-UFS4.0-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 DL_Data and AFC/NACK Packet details.
Error Events, Search, and Filter
PGY-UFS4.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 PPGGY-UFS3.X-PA software simplifies this by listing events while decoding the captured data. Search and Fliter 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 Multi-View
PGY-UFS4.0-PA UFS Protocol Analyzer provides a USB3.0 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. Solder-in probe tips that can be soldered directly to test pads between the UFS host and device. This probe tip has high analog bandwidth to boost the HSG5B (23.32Gbps) signals. The active circuit in the probe tip efficiently drives the low-power MPHY signal to UFS 4.0 Protocol Analyzer for error-free Protocol Analysis at UFS 4.0 speeds. Many of the UFS 4.0 development platforms have an SMPM connector to access the MPHY Signals. To probe such devices, Prodigy Technovations offers SMPM probe tips. SMPM probe tips have mating SMPM connector with DUT. This makes it convenient to connect to the DUT and analyze UFS 4.0 Protocol data.
