Power-aware dynamic encoding

Abstract:

Dynamic power-aware encoding method and apparatus is presented based on a various embodiments described herein. The experimental results confirmed that a desirable reduction in the toggling rate in the decompressed test stimulus is achievable by reasonable overhead (ATPG time, hardware overhead and pattern inflation) typically without degradation of a compression ratio. The performed experimental evaluation confirms that the described embodiments can support aggressive scan compression, efficient dynamic pattern compaction and a reduction of toggling rate in the decompressed test stimulus.
