19、 and Definitions This document uses the same acronyms and definitions as the Base specification: UUT: Unit under Test, meaning a device that is to be tested for conformance to the standard. 3. GENERAL VALIDATION CRITERIA 3.1 Execution of Other Test Specifications In order to ensure 1394 device inter

20、operability, other organizations have already defined compliance/interoperability specifications or are in the process of doing so. Although these specifications are targeted toward interoperability certification efforts in the consumer electronics market, they also form the basis for basic 1394 dev

21、ice connectivity testing, and therefore are applicable to the testing efforts as defined in this document. Tests covered by these specifications will not be explicitly specified by this document. Only additional tests required for compliance verification with the AS5643 standard will be explicitly s

22、pecified.The following test specifications will be executed fully or in part (when applicable) prior to tests specified in this document: AS5643/1 Test Plan or other Physical Layer Test Specifications 1394 Trade Association Document 2002005, Base 1394 Test Suite Definition Version 1.0 After successf

23、ully passing the specified test program, specific tests shall be performed in order to pass environmental, vibration, and other specific tests that are beyond the scope of this specification. SAE AS5657 Page 4 of 15 FIGURE 1 - TEST SEQUENCE SAE AS5657 Page 5 of 15 3.2 Black Box Testing For all speci

24、fied tests, the UUT will be viewed as a “black box” with the 1394 connector being the only access portal to the UUT. “Black Box” also means that the test person has little or no knowledge about the functions, features, and internal operations of the UUT.4. INDIVIDUAL DEVICE VERIFICATION (UUT ONLY) T

25、he tests specified in this section should verify basic device compliance with standard 1394 test criteria and are intended to ensure basic 1394 interoperability and requirements validation. They should target device validation and characterization on a single device basis, only connected to appropri

26、ate Test/Validation Instruments as needed. This document also requires that the UUT has successfully passed physical layer tests as defined in their respective Physical Layer Test Specifications. This means that the UUT conforms to all wiring, signal integrity, and physical layer transmission charac

27、teristics.4.1 Test Setup A typical test setup is shown below. Black box testing requires the UUT (completely powered up) to be connected to an adequate test instrument. Unless specified differently, the tests can be performed with commercial 1394b test equipment, i.e., 1394b Bus Analyzers.FIGURE 2 -

28、 “BLACK BOX” TEST SETUP The cabling (including wires and connectors) used in this Test Setup must itself conform to applicable Physical Layer Test Plans. It should have been tested by itself. The UUTs compliance is verified and tested by running test functions on these instruments. Tests can include

29、, but are not limited to: PHY Register Read/Writes Asynchronous Stream packets verification Timing verification This document does not specify environmental test parameters for the UUT. These parameters (e.g., temperature, vibration, noise, etc.) are specified in the program/device specific definiti

30、ons. All tests shall be performed in the specifiedenvironmental conditions for each UUT.4.2 Physical Layer Tests 4.2.1 PHY Chip Register Verification The following tests target PHY register validation. PHY registers define device functionality and therefore device compliance and interoperability on

31、the bus. Only proper PHY register settings guarantee proper device functionality. SAE AS5657 Page 6 of 15 Instrumentation requirements: Commercial data analyzer with remote PHY register read capability. Writes to the remote registers are not required for these tests. Automated test capabilities are

32、not required but can reduce validation time. 4.2.1.1 Link Control Register This bit shall be tested according to Trade Association Document 2002005, Base 1394 Test Suite Definition Version 1.0. 4.2.1.2 Power Class RegisterThis bit shall be tested according to 1394 Trade Association Document 2002005,

33、 Base 1394 Test Suite Definition Version 1.0.4.2.1.3 Root Hold-off RegisterThe base specification defines that only CCs can be root nodes. The following test verifies the corresponding control bit setting. Connect UUT to Data Analyzer. Read PHY register RHB field value and compare against Pass/Fail

34、criteria Pass/Fail Criteria: Pass: See Table 1 Fail: anything else TABLE 1 - RHB REGISTER VALUES Field Name Required Register Value Requirement Level RHB 12if UUT is a CC 02if UUT is a remote node Mandatory4.2.1.4 Maximum Port Speed Register For physical layer chips with programmable port speed sett

35、ings, the maximum port speed should be verified. The speed value must not exceed the speed rating of used physical media (cable) or the specified network speed. This test should be performed for each available PHY port. Connect UUT (port0) to Data Analyzer. Read PHY register MAX_PORT_SPEED field and

36、 compare against Pass/Fail criteria. Pass/Fail Criteria: Pass: See Table 2 Fail: anything else Repeat for all other available ports. SAE AS5657 Page 7 of 15 TABLE 2 - MAX_PORT_SPEED REGISTER VALUES Field Name Required Register Value Requirement Level Max_Port_Speed 0002if cabling supports S100 only

38、fields (for each port separately) has to be verified. A negotiated speed lower than the maximum port speed is a strong indication of a failed speed negotiation, and therefore, a faulty/unreliable physical layer connection. Connect UUT (port1) to Data Analyzer. Read NEGOTIATED _SPEED register for all

39、 connected PHY ports and compare against Pass/Fail criteria.
