You must not invoke the following private instructions at any instance because these
instructions can potentially damage the device, rendering the device useless:

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.

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.

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