BSDL Files

Find BSDL files via the links provided below. The Boundary-Scan Description Language (BSDL) is a subset of VHDL (VHSIC Hardware Description Language) that describes how boundary-scan (JTAG) is implemented in a device and how it operates. Boundary-scan tools usually require that the user supply BSDL files for the devices being used in order to properly generate test vectors and perform in-system programming and functional testing.

To help you quickly locate BSDL files for your boundary-scan compatible devices, Corelis is providing the links below to popular semiconductor vendors and their BSDL files (if available).

The Boundary-Scan Description Language (BSDL) specification is contained in the IEEE 1149.1 standard which can be obtained from You can also read our Boundary Scan Description Language (BSDL) tutorial.
