ScanExpress DFT Analyzer
Test Coverage Analysis
ScanExpress DFT Analyzer™ is a test coverage calculation tool
that provides users with precise pin, net, and device coverage
statistics on any board targeted for boundary-scan testing. The
tool is able to quantify test coverage into meaningful numbers
in which a user can immediately translate to identify areas of a
board that are fully tested, partially tested, or are not tested
at all. The tool also helps design and test engineers increase
fault coverage and reduce boundary-scan test program development
time by identifying fault coverage limitations.
ScanExpress DFT Analyzer intelligently combines the testability
reports generated by ScanExpress TPG and provides both summary
and detailed test coverage reports for the board. Users can view
the reports by using the built-in report browser or by importing
the data directly to a spreadsheet or database. The combined
test coverage reports help engineers to maximize the value of
boundary-scan by reducing the need for external test point
access to specific nets and pins. The figure to the right
depicts a test coverage summary report from the main ScanExpress
DFT Analyzer window.
ScanExpress DFT Analyzer is ideally used after schematic capture
and before PCB layout. At this stage of product development,
ScanExpress DFT Analyzer efficiently creates a set of
comprehensive test coverage reports that identify all of the
boundary-scan nets and pins, classifying them into basic
testability groups. The report also recommends where to add test
point pads for physical "bed-of-nails" access if additional test
coverage is required using other test methods.
