Introduction This introduction i

7、s not part of IEEE Std 1581-2011, IEEE Standard for Static Component Interconnection Test Protocol and Architecture. In 1999, an idea was presented, at the International Test Conference (ITC), on testing the interconnections between certain complex memory devices that do not comply with IEEE Std 114

8、9.1 and other IEEE 1149.1 devices on a printed circuit board (PCB). The process of testing for interconnections is also referred to as interconnect testing and connectivity testing. The complex memories at which this technique is directed are those that cannot be conveniently tested using static tes

9、t techniques, such as boundary scan, because they involve high frequencies. Another reason is that those devices often contain a state machine that can be exercised only using data and address lines that are yet to be tested. The idea presented was a test method comprising a combinational function d

10、esigned into the memory. The combinational function replaced the memory function when the test mode was activated and did not otherwise interfere with memory operation of the memory. Thus, the complexity of the memory may be bypassed during test by the combinational function. The idea was described

11、in two papers. One paper described the theoretical background of the combinational function in relation to detection and diagnosis of defects (Biewenga et al. B1).aThe other paper described a practical approach: an implementation in synchronous dynamic random access memory (SDRAM) (de Jong et al. B2

12、). The novel idea attracted much attention from the test community. A fringe meeting at ITC was held and resulted in a plan to have this idea captured within a test standard. Since implementation would be within the silicon of memory devices, standardization was planned to start within JEDEC Solid S

13、tate Technology Association (JEDEC). It was later decided to first develop an IEEE standard, as this approach would lead to a more extensive and unambiguous description of the implementation. The continued need for JEDEC involvement was, however, clearly recognized. In 2000, first attempts were made

14、 to form a study group of people enthusiastic about this novel test concept. This group was the precursor of the IEEE working group. At the beginning of 2001, the P1581 Working Group was officially formed after having had two preliminary telephone conferences. Shortly after formation of the working

15、group, one member found an alternative to the method first introduced in 1999. This method, a simple extension of traditional connectivity tests such as NAND trees, etc., was brought to the attention of the working group in 2001. In addition, the original proposal for standardization was extended wi

16、th a number of test mode entry/exit methods as well as a set of general rules for test logic implementations. This standard is the result of the work performed to date by the P1581 Working Group.

42、iew 1.1 Scope This standard defines a low-cost method for testing the interconnection of discrete, complex memory integrated circuits (ICs) where additional pins for testing are not available and implementing boundary scan (IEEE Std 1149.1)1is not feasible. This standard describes the implementation

43、 rules for the test logic and test mode access/exit methods in compliant ICs. The standard is limited to the behavioral description of the implementation and will not include the technical design for the test logic or test mode control circuitry. 1.2 Purpose There is currently no defined, independen

44、t standard for test technology in memory devices. Each vendor is free in the way of implementing test hardware functionality in their ICs to support connectivity tests. Without an independent standard, testability is reduced, and test coverage may not be complete making the test technology less usef

45、ul for others. This standard will improve interconnect testing for discrete memory devices by specifying implementation rules for test logic and test mode entry/exit methods included in memory ICs as guidance both to IC vendors implementing the standard and to test equipment manufacturers supporting

46、 this standard. The standard is aimed at ICs that are otherwise not provisioned with design for testability (DFT) for any reason, targeting primarily memory devices but also allowing for implementation in other devices, while supporting the highest fault coverage and pin-level diagnostics of board-l

47、evel connectivity faults on such devices. 1Information on normative references can be found in Clause 2.
