The Hierarchical Scan Description Language is a specialized language for describing scan-related structures in electronic circuits. An HSDL file can contain information that scan-design or scan-test software uses when working with a design.
HSDL files are source files for software that supports this language and may be read as part of a scan-analysis or test-development workflow.
An HSDL file can usually be inspected in any text editor because it is a language source file. A text editor will show the contents but will not validate or process the scan description.
To use the file, open or import it in electronic design automation or scan-test software that supports the Hierarchical Scan Description Language.
Conversion of an HSDL file depends on the electronic design automation or scan-test software that supports the language. If the software provides an export function for the required target format, use that function to create the converted file.
If no such export is available, the HSDL source must be adapted manually for the target tool and checked in that tool.
