Zusammenfassung
The IEEE 1687 Std. provides an efficient access methodology for embedded instruments in complex system-on-achip designs by introducing reconfigurable scan networks. This flexibility enables the reduction of the overall test access time, which significantly decreases the test costs compared to the conventional daisy-chaining method. However, the new access methodology strictly requires new effective test schedulers that consider multi-power domains with individual constraints, as given on the chip-level. This work proposes a novel SAT-based optimization modeling scheme for complex IEEE 1687 networks with multi-power.
