1 Prtcl Insight UFS Test Executive UFS20COMP Test Executive prvides cmplete prtcl debug and analysis f UFS devices, including deep packet inspectin, stress testing, custm test case executin, and CTS and UFSA interperability verificatin. It is available as a 12 mnth license with an annual renewal ptin, and perates in cnjunctin with the Keysight Technlgies U4431A MIPI M-PHY prtcl analyzer. Key Features and Benefits Deep packet inspectin perfrmed with a unique prtcl-aware Rule Checker engine with full prtcl decde and rule checking against the JEDEC JESD220B UFS 2.0 spec and JESD224 UFS CTS. Fr example, Test Executive evaluates ver 30 majr packet characteristics against the UFS 2.0 standard alng with the fur checks required by the CTS fr Test Case cmpliance, prviding a much richer picture f packet characteristics and device behavir. Perfrm extensive stress testing executing hundreds f thusands f tests with multiple packet inspectin rules per test. Execute any test r set f tests against any selectin f LUNs, speeds and link widths. Run the tests in ascending, descending r randm rder, lped in nest rder with flexibility t specify the nesting rder by LUN, speed, link width r test case. Stp after any number f lps, Warnings r Failures. All failures and warnings are tagged, allwing the user t find, view and analyze the full test sequence in the Keysight analyzer. Design custm test cases t test crner cases r intrduce errrs fr margin, stress, r errr recvery testing. Test Case Builder allws cmplex test case creatin, with virtually unlimited transactins, device cntrl, and cmmand and respnse packet cnstructin, Data Buffer and Paylad supprt, and Lp and Cmpare functins. Lcal and glbal variables and run cnditins are used t create test case cnditins. Syntax checker verifies custm test case validity. Perfrm cmpliance testing t the JEDEC JESD224 Universal Flash Strage (UFS) Prtcl CTS, t verify cmpliance with JESD220B UFS Standard versin 1.1A.

3 Deep Packet Inspectin and Analysis Failure and Warning status flags A Warning is any respnse packet that des nt cnfrm t a shall specified in JESD220B UFS 2.0. A Failure is a respnse packet that des nt meet a rule specified in JESD224 prtcl CTS Pass and Inf status flags Any respnse packet that cnfrms t bth JESD220B and JESD224 is marked as Pass Any packets nt inspected due t run cnditins are highlighted and explained with the Inf flag Grup, filter and summarize test results By test parameters status, test categry, individual tests, r test rules By packet characteristics packet number, byte, LUN, speed, link Full packet decde in 8, 16 r 32 bit mde Offline analysis f previusly acquired packets Summary reprts and full file exprts Applicatins Device cmpliance and Hst-Device interperability verificatin f silicn and end-prducts Initial device turn-n debug System integratin debug Interp wrkshp preparatin UFSA device cmpliance certificatin Specificatins Test Executive perates in cnjunctin with the Keysight Technlgies U4431A MIPI M-PHY prtcl analyzer, and supprts UFS lane widths and speeds within the capabilities f the U4431A hardware. Inspectin f the entire packet ffers a much richer picture f packet prtcl characteristics and device behavir. Belw is an example f the additinal detail prvided in the Basic UPIU Header Check, Data In Check and Respnse UPIU Check:

4 Basic UPIU Header Checks - All Messages are checked fr prper UIPI headers: The message structure is >= 32 Bytes and ends n a 4 byte bundary 1.1. TRANSACTION TYPE Bth the DD and HD bits are set t 0 That it is a valid and defined Transactin Type 1.2. FLAGS This field is 0 unless the Transactin Type is Cmmand r Respnse N reserved flag bits are set in any Transactin Type IF Transactin Type is cmmand: R & W flag are nt bth set Flag Attribute Type is nt ACA IF Transactin Type is Respnse U & O flags are nt bth set 1.3. LUN N Checks 1.4. TASK TAG N checks as all values are valid 1.5. COMMAND SET TYPE Bits [7:4] are reserved and that these bits are 0 The value f bits[3:0] is 0 r h8 t hf. A value f 1 is UFS Specific cmmand which is nt currently supprted A value f 2-7 is reserved 1.6. QUERY FUNCTION / TASK MANAG. FUNCTION This field is 0 unless the Transactin Type is Task Management Request, Query Request r Query Respnse IF Transactin Type is Task Management Request The value is ne f the fllwing valid values h1, h2, h4, h8, h80, h81 IF Transactin Type is Query Request r Query The value is ne f the fllwing valid values h1, h40 t h7f, h81, hc0 t hff 1.7. RESPONSE This field is 0 unless the Transactin Type is Task Management Respnse, Respnse, reject r Query Respnse IF Transactin Type is Task Management Respnse, respnse, reject r Query Respnse The value is nt a reserved value, h80 t hff 1.8. STATUS This field is 0 unless the Transactin Type is Respnse IF Transactin Type is Respnse The value is a ne f the fllwing valid values h0, h2, h4, h8, h18, h28, h30, h TOTAL EHS LENGTH This value shall be 0 has Extra Header Segments are nt supprted DEVICE INFORMATION This field is 0 unless the Transactin Type is Respnse r Query Respnse IF the Transactin Type is Respnse r Query Respnse The value is a ne f the fllwing valid values h0 r h DATA SEGMENT LENGTH That the number f bytes in the Data Segment are equal t r greater than the Data Segment Length field IF greater nt greater than 3 bytes All padding byte are 0

5 Respnse UPIU Check The Status and Respnse fields match the expected values The flags match the expected flags IF an verflw r underflw flag is set The Residual Transfer cunt is nn zer and equal t the expected value 2.1 SENSE DATA CHECKS IF the Data Segment Length is nn zer the Sense Data is checked: The Data Segment Length shall equal 20 The Sense Data Length shall equal the Data Segment Length - 2 (18) The fllwing fields f the Sense Data Frmat are static: Respnse Cde = 0x70 Obslete = 0x00 Data In Checks FILEMARK, EOM, ILI, Reserved = 0x0 Additinal Sense Length = 0x0A Cmmand Specific Infrmatin (4Bytes) = 0x00 0x00 0x00 0x00 Field Replaceable Unit Cde = 0x00 Sense Key Specific Infrmatin (3 Bytes) = 0x00 0x00 0x00 The fllwing fields are cmpared t an expected value (NOTE each check can be ignred by setting the value t X ) Sense Infrmatin Valid Sense Key Sense Infrmatin Additinal Sense Cde (can be a list f cdes t cmpare t) Additinal Sense Cde Qualifier (can be a list f cdes t cmpare t) This checks the Transactin Specific Fields f the Data In UPIU The Data Buffer Offset value shall equal the specified value The Data Transfer Cunt shall match the Data Segment Length The Reserved fields shall be 0 Prgram Outputs Test Executive issues UFS Cmmand packets t a device and captures and analyses the Respnse packets. Fr example, fr UFS_Inquiry_01 the fllwing are checked in the Respnse packet: 2. UFS_Inquiry 2.1. UFS_Inquiry_01 Basic UPIU Header Check n the Respnse and Data In message Data In Check n the Data In message Respnse UPIU Check n the Respnse message. If Sense data is present the default value checks are perfrmed but the expected value checks are ignred Status shuld be GOOD Respnse shuld Target Success The fllwing is checked n the Data In message: The crrect number f bytes are returned (36) with a maximum f 36 Bytes The Data Buffer Offset is equal t 0 The Data Transfer Cunt matches the Data Segment Length The first 8 bytes f the match the definitin in the UFS specificatin Reprts the Vendr Identificatin, Prduct Identificatin, Prduct Revisin Level

6 Sme f the checks are required fr cmpliance testing, but many f the checks are nt. These additinal checks prvide deeper prtcl insight by lking fr packet errrs as defined in the UFS specificatin. General Characteristics System requirements: Windws 7 32 r 64 bit OS are supprted. Minimum 12Gb RAM recmmended fr stress testing with multilevel gruping. The Keysight U4431A MIPI M-PHY prtcl analyzer is required fr peratin. Test Executive is cmpatible with Keysight U4431A applicatin sftware v6.1 r later and firmware v r later.
