BSDLCustomizer is a TCL script which is used to modify the BSDL file’s

port definitions and boundary-scan chain groups’ attributes according to

the design and pin assignments from the Quartus II software PIN file.

Once you run the generic BSDL file and your PIN file through the

BSDLCustomizer tool, a modified BSDL file is created which should be

used for the boundary-scan test.

Before running the boundary scan test on your board make sure that the

nCONFIG pin is externally pulled low and that the nSTATUS pin is low.

For more information on the BSDLCustomizer tool, refer to the

BSDLCustomizer User Guide that you can download with the

BSDLCustomizer tool from the Altera website at www.altera.com.
