Boundary-Scan Description Language Support

The boundary-scan description language (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. To download BSDL files for IEEE Std. 1149.1-compliant

Cyclone III device family, visit the Altera Download Center.

1 BSDL files for IEEE std. 1149.1-compliant Cyclone III LS devices can also be generated

using version 9.0 and later of the Quartus II software.

To perform BST on a configured device, a post configuration BSDL file that is

customized to your design is required. Post configuration BSDL file generation with

BSDL Customizer script (available on the Altera Download Center) is for Cyclone III

devices only.

Use version 9.0 and later of the Quartus II software to create a post configuration

BSDL file for Cyclone III LS devices.

f For information on the procedures to generate the generic and post configuration

BSDL files with Quartus II software, visit the Altera Download Center.
