What is a BSDL file and how important is it in boundary scan?
A BSDL file, which is the acronym for Boundary Scan Description Language file, is a subset of Very High Speed IC Hardware Description Language (VHDL) that describes the boundary scan device package, pin description and boundary scan cell of the input and output pins. The BSDL file is very important in generating a boundary scan test. Without a BSDL file, it is impossible to generate any boundary scan test.
See below for a sample BSDL file.
