The photophysical properties of a hydrazone-based switch, which can be induced using pH to yield three stable configurations (QPH-E, QPH-Z-H + and QPH-Z-H 22+ ) and another unstable configuration (QPH-Z). The three stable configuration have been investigated by means of density functional theory (DFT) and time-dependent density functional theory (TDDFT). A generalized gradient...
A scheme that ATPG-based technique for reducing shift and capture power during scan testing is presented without any influence on fault coverage. This paper presents an X-filling approach called adjacent backtracing fill (AB-fill). After AB-fill approach for at-speed scan testing, all of test patterns have assigned as partially-specified values with a small number of don't care bits (x) as in test...
This paper presents an input test data compaction and scan power reduction technique. We present new design for testability (DFT) method to hold values when some of test data in test cubes are not need to be changed. In our implementation, we present new algorithm called 2-D compaction to compact test cubes as less as possible and fill unspecified bits with specified value when necessary. Experimental...
During built-in self-test (BIST), the set of patterns generated by a pseudo-random pattern generator may use longer time and more power consumption in testing. In this paper, we propose a novel hardware architecture base on "LBIST Controller" to reduce test application time and test power consumption. Give a test cubes for stuck-at faults contain unspecified bit generated by a sequential...
