Chapter 13: IEEE 1149.1 (JTAG) Boundary-Scan Testing for MAX II Devices

Boundary-Scan Description Language (BSDL) Support
Boundary-Scan Description Language (BSDL) Support
The BSDL—a subset of VHDL—provides a syntax that allows you to describe the
features of an IEEE Std. 1149.1 BST-capable device that can be tested. Test software
development systems then use the BSDL files for test generation, analysis, failure
diagnostics, and in-system programming.

devices, refer to the Altera website at www.altera.com.
Conclusion
The IEEE Std. 1149.1 BST circuitry available in MAX II devices provides a cost-
effective and efficient way to test systems that contain devices with tight lead spacing.
Circuit boards with Altera and other IEEE Std. 1149.1-compliant devices can use the
EXTEST, SAMPLE/PRELOAD, and BYPASSmodes to create serial patterns that
internally test the pin connections between devices and check device operation.
