  1. UFS Characterization and Compliance Testing Perry Keller Compliance and Enablement Chairman UFS Assn. Board of Directors Digital Applications and Standards Lead Agilent Technologies Mobile Forum 2013

  2. 3rd Wave of Personal Computing Windows 8 Windows PHONE Windows ios blackberry android Mac os Cloud-Based Services WiFi Ethernet LAN Client- Server Broadband Mobile Web Servers Hundreds of Millions of users Mobile Connected Society Billions of users Millions of Apps Tens of Thousands of Apps Less than 10 watts Greater than 100 watts 10’s of watts

  3. 3rd Wave Computing Infrastructure Continuous Internet Landline speed Processor And Modem Multiple cores and faster clock rate Flash RAM Double (and then redouble) clock rate Increased capacity and transfer rate, Server class protocol eMMC V UFS LPDDR/2 V LPDDR3 More channels, wider busses Desktop class performance powered by a battery!

  4. Universal Flash Storage (UFS)The Next Generation Mobile Storage Built on e.MMC heritage • Incorporate e.MMC features adopted by mobile systems for a smooth transition in mobile applications SSD Technology Reliability & Low Power Server Class SCSI CMD Set e.MMC

  5. UFS Ecosystem UFS Device • The UFS Standard is developed in JEDEC JC64 committee • Physical and link layer standards developed by MIPI • The Universal Flash Storage Association (UFSA) focuses on ecosystem enablement and compliance certification UFS Enabled Chipset Host System Developer Standards & Trade Associations MIPI Alliance OS and Driver UFS is a pioneer in cross-standard integration

  6. What is the UFSA? The Universal Flash Storage Association (UFSA) was founded in 2010 as an open Trade Association to promote widespread industry adoption and acceptance of the UFS standard Primary missions: • UFS technology promotion • UFS infrastructure enablement • Product compliance and certification management • Technical input into JEDEC / MIPI for future specifications

  7. Principles of Certification • Assure Devices and Hosts interoperate reliably • Uniform positive customer experience • Maximum breadth of compatible products • Allows products to differentiate on basis of core competencies • All parts of the specification are covered • Embedded and removable devices supported • Maximize benefits to developers at minimum cost • Mix of interface and interop tests provides maximum coverage with least effort • Test matrix focuses on key predictors of conformance and interoperability • Technical test procedures developed by the experts in MIPI, Jedec, etc. who wrote the spec itself • “Class” certification supports product enhancement without recertification • IP protection integral part of the process • Promote completeness and advancement of UFS/MIPI specifications • “Real life” input to specification developers • Assure ultimate integrity of UFS brand • Vendor independent (3rd party) testing, certified by UFSA • Integrated with UFSA logo program

  8. UFS Certification Process Accredited Labs Logo Committee Compliance Certificate Adopter Member Products Success Criteria Compliance Test Spec JC 64.5 Logo License Compliance Committee UFS Test Spec What & How to Measure MIPI M-Phy & Unipro Test WGs M-Phy/Unipro Test Spec UTP Test Spec Logo Branded Product

  9. Compliance Test Elements • Test platforms • Provided by T&M vendors and IP developers • Instrumentation • Test fixtures • “Golden” references • M-Phy, Unipro, UFS Test procedures • Developed by the specification experts in Jedec and MIPI • Rigorous, repeatable, technically clear • Maximum coverage of entire specification • Useful for development, debug, characterization and compliance • UFS Test Specification • Developed by UFSA contributor members • Provided to UFSA adopter members • Defines certification test matrix • Clear description of test configurations • Simplifies development team scheduling and budgeting

  12. Physical Layer Testing • Typical platform components: • Metrology grade test fixtures • Oscilloscopes • Bit Error Rate Testers • Waveform generators • Network Analyzers • Time Domain Reflectometers • Scope of testing • M-Phy Tx • M-Phy Rx • UFS channel (Tx ball to Rx ball) • Power integrity (future)

  13. Protocol Testing • Typical platform components: • Host, Device, snoop test fixtures • Oscilloscope protocol decoder • Protocol analyzer • Protocol generator/exerciser • Instrumented “golden” hosts and devices • Scope of testing • Unipro • UFS Transport Layer (UTP)

  14. Interoperability Testing • Typical platform components: • Host, Device, snoop test fixtures • Set of “Golden” hosts (for device test) • Set of “Golden” devices (for host test) • Host test application or procedures • Phy/Protocol test equipment (for debugging) • Scope of testing • Complete UFS HW/SW stack • Interoperation with defined set of “Golden” hosts/devices UFS UFS UFS UFS Device DUTs Golden Device Host DUT Golden Host

  15. Workshops, Plugfests And Certification • UFS Workshop • Trial execution of UFS Compliance Test Specification • By Invitation only • Test and debug of the UFS CTS itself, test platforms and individual test procedures • Test results are anonymizedbefore Compliance Committee review • UFS Plugfest • Open to all UFSA adopter and above members under NDA • Standard CTS executed in private • Test results returned only to UFSA member undergoing test • Learnings used by CTC to improve CTS and generate feedback to partner organizations (individual test results are anonymized before committee review • Certification Test • Provided as service by certified test houses (generally for-fee, no UFSA fee) • Results returned to company requesting test • Certificate of Compliance issued by test house to UFSA Adopters if all tests pass

  16. Key Take-Aways • 3rd wave of personal computing requires complete infrastructure update • UFS is the next generation of mobile mass storage engineered by the industry to enable 3rd wave • UFS is the first memory technology to be backed by formal certification program • The UFSA is an industry driven organization supporting UFS ecosystem and assuring end-user confidence in UFS • For more information: • www.universalflash.org • www.jedec.org • www.mipi.org
