ABSTRACT:
The invention includes an apparatuses and associated methods for controlling dynamic modification of a testing scan path using a control scan path. In one embodiment, an apparatus includes a testing scan path and a control scan path. The testing scan path includes testing components and at least one hierarchy-enabling component. In one embodiment, the control scan path includes at least one control component coupled to the at least one hierarchy-enabling component for controlling dynamic modification of the testing scan path. In one embodiment, the control scan path includes the at least one hierarchy-enabling component, wherein the at least one hierarchy-enabling component is adapted for dynamically modifying the testing scan path using the control scan path. The dynamic modification of the testing scan path may include modifying a hierarchy of the testing scan path, such as selecting or deselecting one or more hierarchical levels of the testing scan path.
