OverviewThe STIL environment supports transferring tester-independent test programs to a specific automated testingequip

25、ment (ATE) system. Although native STIL data are tester independent, the actual process of mappingthe test program onto tester resources may be critical, and it is necessary to be able to completely andunambiguously specify how the STIL programs and patterns are mapped onto the tester resources. TRC

26、(which stands for either tester resource constraints or tester rules checking, depending on the usage) is anextension to the STIL language to facilitate this operation. Figure 1 shows the usage model for tester targeting. The four ways that the TRC statements come into playin the flow of data from d

27、esign to test are indicated by the circled numbers in the diagram. These four usesare defined as follows:a) Tester rules checking: As early as possible in the process of inserting “Design for Test” logic andgeneration of test patterns, the rules of the target tester are identified by means of the TR

28、C filedefining the target tester.b) Tester resource reporting: As part of the pattern generation process, a report of resources requiredfor the pattern may be created in TRC format. This information is available for test planningpurposes, such as 1) when a pattern is for an embedded core to be integ

29、rated into a chip or 2) fortester scheduling purposes. Each resource report is associated with a particular STIL file/stream.The resource report data may be a separate file (as implied in the above diagram) or may be includedin the STIL pattern file.c) Tester resource targeting: The process of teste

30、r targeting is that of adding additional informationinto the STIL file/streams that specifies how the resources of a given tester are to be assigned. Notethe bars on the left side of the diagram, which indicate that this targeting operation can be done inone of three places: 1) by the EDA software t

31、hat generates the patterns, 2) by software created by thetest user, or 3) by the ATE sofware that loads the STIL patterns.d) Tester resource loading: The tester loader is a process that maps the device-oriented STIL data tothe resources of the tester. There may or may not be targeting information pr

32、ovided. If targetinginformation is not present, then the loader is expected to do the job of assigning resources. Iftargeting information is present, then it is to be used to direct the resource assignment.IEEEStd 1450.3-2007 IEEE STANDARD FOR EXTENSIONS TO STIL2 Copyright 2007 IEEE. All rights rese

33、rved.Note that the semantics of the various TRC statements change, based on which flow is being addressed;i.e., in a constraint flow, the TRC statements provide a set of rules that are to be applied to a set of data andan error shall be generated if the test pattern data does not conform to the rule

34、s; in a report flow, the sameTRC statements are providing a summary of test pattern data regardless of whether it conforms to any givenTRC constraints. Most TRC statements can be used in either context. The definitions in this standard arewritten from the constraint point of view.1.1 Scope Define st

35、ructures in STIL for the specification of resource mapping of ATE hardware architectures.An example of resource mapping is the assignment of tester resources to waveform characters thatare used in STIL vectors. Define structures in STIL for including ATE-specific instructions in-line with the STIL d

36、ata. Define structures in STIL that allow for “incremental processing” whereby, a set of STIL files maybe targeted to multiple ATE systems by allowing separately identified ATE data to coexist. Define structures in STIL for defining tester rules checks to ensure that the set of generated STILfiles c

37、onform to the selected resources on one or more ATE systems. Define structures in STIL for the specification of the resources required for the execution of a set ofSTIL files on a given ATE system.1.2 PurposeTransferring “tester independent” test program/pattern data as represented in STIL to a spec

38、ific ATE systemis a desired capability. It is required to be able to completely and unambiguously specify how the STILprogram/patterns are mapped onto a specific testers resources. Because of the various different use modelsfor the creation and consumption of test data, it is necessary to enable cer

The STIL language extensions enable the user/creator astandard way of specifying and controlling the application

42、of test program/pattern data to specific ATEsystems to the extent necessary for each use model scenario.1.3 TRC limitationsIn setting the scope for any standard, some issues are identified and determined not to be defined. Thefollowing is a list of issues that are not in the scope of this standard:a

43、) Violations: The tester-targeting operation naturally leads to situations where a given set ofconstraints cannot be met. It is not in the scope of this standard to define the content or format ofsuch constraint rule violations.b) Completeness: The variations in architecture of various ATE systems m

44、akes it virtually impossibleto address all the nuances and corner cases of each design. It is the intent of this standard to providea common way of describing key common attributes. This standard is intended to address 80% ofthe issues involved with TRC operations, because the effort to address the

45、remaining 20% is toocomplex and would make the standard unwieldy to apply in general.2.
