IEEE 1687 (iJTAG) standard introduces a methodology for accessing the increasing number
of embedded instruments found in modern System-on-Chips. Retargeting is defined by
iJTAG as the procedure of translating instrument-level patterns to system-level scan vectors
for a certain network organization. The analysis and the design of an on-chip retargeting
engine is presented in this paper. Performing retargeting on-chip enables the execution of
life-time dependability procedures using embedded instruments. The proposed engine is …

IEEE 1687 (iJTAG) standard introduces a methodology for accessing the increasing number of embedded instruments found in modern System-on-Chips. Retargeting is defined by iJTAG as the procedure of translating instrument-level patterns to system-level scan vectors for a certain network organization. The analysis and the design of an on-chip retargeting engine is presented in this paper. Performing retargeting on-chip enables the execution of life-time dependability procedures using embedded instruments. The proposed engine is capable of retargeting instruments' patterns using an optimized model of the network, which is extracted by resolving the dependencies between the data registers of the instruments and the network-state registers.
