Glossary:Hierarchical Instrument

Jump to: navigation, search


An instrument that also provides a hierarchical connection by passing on, at a minimum, the Select-Instrument signal and the TDI-TDO serial scan-path which may be referred to, using the IEEE 1500 nomenclature, as the WSI-WSO serial scan-path to distinguish it from the serial scan path in the 1149.1-Zone. Basically, a Hierarchical Instrument provides access to other instruments that do not require a direct IR-Scan.
