Abstract

Software-based path delay fault testing (SPDFT) has been used to identify faulty chips that cannot meet timing constraints due to gross delay defects. In this paper, we propose using SPDFT for a new purpose-aggressively selecting the operating point of a variation-affected design. In order to use SPDFT for this purpose, test routines must provide high coverage of potentially-critical paths and must have low dynamic performance overhead. We describe how to apply SPDFT for selecting an energy-efficient operating point for a variation-affected processor and demonstrate that our test routines achieve ample coverage and low overhead.
