The exceedingly large size of fault dictionaries constitutes a fundamental obstacle to their usage. We outline a new method to reduce significantly the size of fault dictionaries. The proposed method partitions the test set and a combined signature is stored for each partition. The new approach aims to provide high diagnostic resolution with a small number of combined signatures. The experimental results show a considerable decrease in the storage requirement of fault dictionaries.
