Abstract(in English) | High launch switching activity in capture mode during at-speed scan testing may lead to excessive IR-drop. Excessive IR-drop causes test-induced yield loss. A test pattern set is classified to a capture-safe pattern set and a capture-unsafe pattern set. If the launch switching activity exceeds the value of threshold, the test patterns are referred to capture-safe patterns. Other patterns are referred to capture-unsafe patterns. Faults detected by only capture-unsafe patterns are defined as unsafe faults. Other faults are defined as safe faults. It is important to generate capture-safe patterns for unsafe faults to avoid test-induced yield loss due to excessive IR-drop. In this paper, test patterns to unsafe faults for analysis are generated and the launch switching activity is analyzed. The information for a pair of a safe faults and its detected pseudo primary output is used for the analysis. Experimental results for ITC'99 benchmark circuits show that 90% of the test patterns for the analysis are capture-safe when a pseudo primary output where safe faults are detected by capture-safe patterns is the same as the pseudo primary output where safe faults are detected by test patterns for the analysis. |
