摘要：
Debug time has become a major issue in post silicon debug because of the increasingly complicated nature of circuit design. However, reducing debug time is a major challenge because of the limited size of the trace buffer used to observe internal signals in the circuit. This study proposes an on-chip error detection method to overcome this challenge. The on-chip process detects the error-suspect window using the pre-calculated golden data stored in the trace buffer. This allows the selective compaction and capture of the debug data in the trace buffer during the error-containing interval. As a result, reducing the number of debug sessions significantly reduces the total debug time. The experimental results on various debug cases show significant reductions in total debug time compared to previous work.
