Modern chips may contain a large number of embedded test, debug, configuration, and monitoring features, called instruments. An instrument and its instrument data, instrument access procedures, may be pre-developed and reused and instruments may be accessed in different ways through the life-time of the chip, which requires retargeting. To address instruments reuse and retargeting, IEEE P1678 specifies a hardware architecture, a hardware description language, and an access procedure description language. In this paper, we investigate how P1687 facilitates instrument access procedure reuse and retargeting.
