| Abstract | Because domino logic design offers smaller area and higher speed than complementary CMOS design, it has been very popularly used to design high-performance processors. However, domino logic suffers from several design problems and one of the most notable ones is the charge-sharing problem. Charge sharing may degrade output voltage level or even cause an erroneous output value (called charge-sharing fault). In fact, charge-sharing faults are extremely resistant to scan test, charge-sharing faults occurring at the border gates cannot be detected by any scan method, due to the missing error caused by early signal arrival time. Further, a killing error might happen in charge-sharing (CS) fault detection for both border gates and non-border gates because of the low-speed testing problem caused again by scan test. The theoretical models of these two types of CS fault are thoroughly derived. An adaptable voltage scan testing technique, which regulates the original power supply voltage (V/sub dd/) is proposed to solve both test errors. Using a proper scan method to compromise the pre-charge situation from earlier arriving signals, and high voltage (V/sub dd/+) to compensate the over-discharge condition from low speed clock. Finally, the test application is presented to insure the testing quality. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
