Optimizing ATE Resources for ATPG Patterns

ATPG patterns today often feature clock signals declared as extensions to default timing in IEEE Standard STIL files. Hence, these clock signals use traditional ATE formats NRZ and RZ/R1. It would be desirable to optimize the clock format usage to RZ/R1 and save precious ATE timesets, which can be easily exhausted by ATPG patterns that are often large in size.
