You can browse boundary-scan description language (BSDL) files by Altera® device family. You can use these BSDL files for pre-configuration boundary-scan test (BST). For post-configuration BSDL files, please refer to the Altera BSDL Support page. You can use the same BSDL file regardless of speed grade or temperature.
You will need an IEEE 1532 BSDL file (programming algorithm) and an in-system configurable (ISC) file (programming data) to execute in-system programmability (ISP). Methods of generating the ISC file can be obtained from the Quartus® Prime Handbook.
