27、12 IEEE Std 1445-1998 This introduction is not part of IEEE Std 1445-1998, IEEE Standard for Digital Test Interchange Format (DTIF). A digital automated test program generator (DATPG) produces test pattern and diagnostic data that can be used for testing printed circuit assemblies on automatic test

28、equipment (ATE). The use of several DATPGs, all with individual output formats, created a need for many unique post-processors to be developed and maintained for the life of the ATE. These post-processors supported the link from specic DATPGs to specic testers. The proliferation of unique formats an

29、d post-processors created logistical support problems and therefore identied a need for standardization. A DATPG and ATE independent output data format is required to limit the number of post-processors (one for each ATE) requiring life cycle support. The digital test interchange format (DTIF) was c

30、hosen because of its wide use and because it was becoming known in industry as the de facto standard. This document provides the basis to standardize digital test information for use on ATE. The digital test information consists of the unit under test (UUT) Model information, Stimulus and Response d

31、ata, Fault Dictionary data, and Probe data. DTIF is unique from other standards such as IEEE P1450 (Draft 0.95, dated July 1998), 1Draft Standard Test Interface Language (STIL) for Digital Test Vector Data, and IEEE Std 1029.1-1991, IEEE Standard for Waveform and Vector Exchange Specication (WA VES)

32、 STIL is being developed to standardize the output interface of existing computer-aided engineering (CAE) tools with the input interface of ATE for integrated circuit (IC) testing only. W A VES is a hardware descriptive language used for dening stimulus and response, and their associated timing for

33、 IC/board-level design. Neither STIL nor WAVES provides for board-level fault diagnostics. A future revision of this standard will consider the use of the information model. 1 IEEE P1450 is an IEEE authorized standards project that was not approved by the IEEE-SA Standards Boardat the time this publ

34、ication went to press. For information about obtaining the draft, contact the IEEE. IEC 61445:2012 IEEE Std 1445-199 - vii - 1. OverviewThe digital test interchange format (DTIF) is designed to provide a mechanism for digital test data inter- change independent of specic digital automated test progr

35、am generators (DATPGs) and test systems. The DTIF provides a neutral database for the development and delivery of digital simulation based test program sets (TPSs). DTIF functionally supports the unit under test (UUT) Model, Stimulus and Response, Fault Dictionary, and Probe databases.1.1 ScopeThis

36、standard denes the information content and the data formats for the interchange of digital test program data between DATPGs and automatic test equipment (ATE) for board-level printed circuit assemblies. This information can be broadly grouped into data that denes the following: a) UUT Model; b) Stim

37、ulus and Response; c) Fault Dictionary; d) Probe.1.2 PurposeThe purpose of this standard is to provide a standard output format for test data generated by a DATPG. A DATPG produces test patterns and fault diagnostic data for ATE. This data is used in applications such as board-level assemblies where diagnostic data interchange is important.1.3 ApplicationThis standard is primarily intended for use by digital simulator developers/maintainers and TPS developers/ maintainers.
