Altera's BSDL files are currently being reviewed for technical accuracy and hardware tested by Altera and an external contractor. After this verification has been completed, a final copy of each BSDL file will be placed on this web site. You can use the same BSDL file regardless of speed grade or temperature.
If you have any questions or concerns about the contents of these files, please visit Altera's mySupport web site.
For information on boundary-scan testing, refer to AN 39 (IEEE 1149.1 (JTAG) Boundary-Scan Testing in Altera Devices) (PDF - 325 KB).
