Eclipse M32 UniPro/UFS Analyzer/Exerciser
The Eclipse M32 analyzes bi-directional UniPro and UFS traffic, performing protocol sequence and timing analysis and packet header and payload inspection, to provide complete protocol debug and analysis of UFS and UniPro devices. Trace Validation uses state machine logic to analyze captured traces algorithmically without user intervention. The Eclipse M32 also provides compliance/conformance verification, as well as margin, corner case, and automated stress testing.
The Eclipse M42 updates the Teledyne LeCroy family of UniPro/UFS protocol analyzers and exercisers. Supporting MIPI M-PHYTM Gear4 at speeds up to 11.8Gbps, the Eclipse M42 stands as the markets most complete analyzer/exerciser. The Eclipse M42 analyzes bi-directional UniPro and UFS traffic, performing protocol sequence and timing analysis and packet header and payload inspection, to provide complete protocol debug and analysis of UFS and UniPro devices.
MIPI® M-PHY is a serial interface technology with high bandwidth capabilities, which is particularly developed for mobile applications to obtain low pin count combined with very good power efficiency. It is targeted to be suitable for multiple protocols and for a wide range of applications.
M-PHY uses lanes for communication. Each lane is a differential pair. M-PHY supports multiple lanes and lanes can be asynchronous.
M-PHY defines both low speed and high speed data rates. Within both low speed and high speed, multiple gears are defined. Low speed uses a Pulse Width Modulation and Gears 1-7 support a range of speeds from 3Mbps up to 576 Mbps. High Speed uses NRZ signaling and supports speeds of .998Gbps up to 11.66Gbps via Gears 1-4. Information transmitted on the lanes uses 8b/10b encoding.
UniPro is a MIPI defined transport specification. Uniport-M is the UniPro transport over M-PHY. UniPro enables upper layer applications to move data over the M-PHY bus although it is Phy layer agnostic. UniPro is applicable to a wide range of Device types such as modems, storage subsystems, Non-volatile memory, displays, and camera sensors. It is also applicable to different types of data traffic such as control messages, bulk data transfer and packetized streaming. A full Layer 1.5-4 specification, UniPro defines packets and frames for moving information across a network from device to device. It also defines the structures and mechanisms for connection management, power and state management, flow control and error handling.
JEDEC defines the Universal Flash Storage (UFS) specification. UFS is a simple, high performance, mass storage device with a serial interface. It is primarily for use in mobile systems, between host processing and mass storage memory devices. The UFS electrical interface is based on the MIPI M-PHY specification which together with the MIPI UniPro specification forms the interconnect of the UFS interface. UFS is based on the SCSI Architectural Model (SAM). The UFS command set is based on the SCSI Primary Command (SPC) and SCSI Block Command (SBC) sets.Protocol Analysis and Traffic Generation
Teledyne LeCroy offers both protocol analyzers and traffic generators or exercisers to address the M-PHY market. Our protocol analyzers offer unique and configurable views that allow users the ability easily visualize the M-PHY traffic. From the low level M-PHY primitives up through the UFS SCSI command sets we show activity on the bus as a complete picture of all events, and allow views to the lowest level bytes or to the highest level command transactions. Our exerciser and expert system analysis run conformance and stress test cases, then verify that the resulting protocol sequences and packets conform to the CTS. Extensive reporting and analysis tools include reports by test parameters – status, individual tests, or test rules, and within tests by packet characteristics such as packet number, byte, speed, link, etc. Summary and full reports and pass/fail reports are also provided.
As a contributing member of both MIPI and JEDEC, Teledyne LeCroy stays informed and up to date on the latest specifications and continues to update the roadmap for their M-PHY and UniPro/UFS tools.
The Eclipse M32 M-PHY Gear 1/2/3 is the right tool for engineers and developers who need to ensure the correct and efficient operation of technologies employing the high data transfer speeds of the UFS and UniPro specifications supported by M-PHY interfaces. Connected to the Controlling PC via Thunderbolt 3, the Eclipse M32 delivers protocol analysis, compliance conformance verification, and automated quality testing in one powerful package. Teledyne LeCroy’s UniPro M Series Protocol Suite provides all the views you need to debug captured data. The Events window shows activity on the bus as a complete picture of all events, and allows drill-down to the lowest level bytes. This unique time-aligned display includes fillers, Prepare, SYNC, Hibern8, sleep, stall and other M-PHY level packets.
Trace Validation powers a number of the Eclipse M32’s most exciting features. It identifies transactions on the link by analyzing millions of packets in a trace capture, then evaluates the complete protocol sequences and individual packets for conformance to the specification. With Trace Validation, complex transactions such as power mode changes, Link Startup Sequence and NAC/Replay events can be automatically analyzed and easily debugged. Trace Validation finds the problems an engineer can’t.
In Conformance Test Suite mode, the Eclipse M32 initiates conformance test cases, then uses Trace Validation to verify that the resulting protocol sequences and packets conform to the CTS. Extensive reporting and analysis tools include reports by test parameters – status, individual tests, or test rules, and within tests by packet characteristics such as packet number, byte, speed, link, etc. Summary and full reports and pass/fail reports are also provided. Exerciser stress testing controls the DUT and executes hundreds of thousands of tests automatically. Stop after any number of loops or No Result Test Cases, and analyze the results with Trace Validation.
