23、 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 beused for testing printed circuit assemblies on automatic test equipment (ATE). The use of several DATPGs,all with indi

24、vidual output formats, created a need for many unique post-processors to be developed andmaintained for the life of the ATE. These post-processors supported the link from specic DATPGs tospecic testers. The proliferation of unique formats and post-processors created logistical support problemsand th

25、erefore identied a need for standardization. A DATPG and ATE independent output data format isrequired to limit the number of post-processors (one for each ATE) requiring life cycle support. The digitaltest interchange format (DTIF) was chosen because of its wide use and because it was becoming know

26、n inindustry as the de facto standard.This document provides the basis to standardize digital test information for use on ATE. The digital testinformation consists of the unit under test (UUT) Model information, Stimulus and Response data, FaultDictionary data, and Probe data.DTIF is unique from oth

27、er standards such as IEEE P1450 (Draft 0.95, dated July 1998),1Draft Standard TestInterface Language (STIL) for Digital Test Vector Data, and IEEE Std 1029.1-1991, IEEE Standard forWaveform and Vector Exchange Specication (WAVES). STIL is being developed to standardize the outputinterface of existin

28、g computer-aided engineering (CAE) tools with the input interface of ATE for integratedcircuit (IC) testing only. WAVES is a hardware descriptive language used for dening stimulus and response,and their associated timing for IC/board-level design. Neither STIL nor WAVES provides for board-levelfault

29、 diagnostics.A future revision of this standard will consider the use of the information model.ParticipantsThe ATPG Subcommittee consisted of the following members who provided signicant input toward thedevelopment of this standard:Mukund U.
