Boundary Scan Products: How to Use Boundry Scan

How to use the ACUTAP tools from ACUGEN Software

in the transition from classic in-circuit board testing to boundary scan testing

For classic in-circuit board testing:

ü Use ACUGEN cluster testing to test clusters of small devices that cannot be tested individually because of disabling (guarding) limitations.

ü Use ACUGEN cluster testing to lower tester pin requirements.

For single device in-circuit boundary scan:

ü Use TESTBSDL tool to generate ICT tests for boundary scan devices.

ü Use TESTBSDL tool to validate BSDL files.

ü Use PROGBSDL tool to modify BSDL files to match circuit board constraints.

ü Use ACUGEN cluster testing to test clusters of small devices that cannot be tested individually because of disabling (guarding) limitations.

ü Use ACUGEN cluster testing to lower tester pin requirements

For long chain boundary scan mixed with in-circuit and

For full boundary scan without in-circuit tester:

ü Use TESTBSDL tool to validate BSDL files.

ü Use PROGBSDL tool to modify BSDL files to match circuit board constraints.

ü Use ACUGEN cluster testing to test non-boundary scan devices that are surrounded by boundary scan parts.
