| Abstract | In coupling delay computation, a Miller factor of more than 2/spl times/ may be necessary to account for active coupling capacitance when modeling the delay of deep submicron circuitry in the presence of active coupling capacitance. We propose an efficient method to estimate this factor such that the delay response of a decoupling circuit model can emulate the original coupling circuit. Under the assumptions of zero initial voltage, equal charge transfer, and 0.5V/sub DD/ as the switching threshold voltage, an upper bound of 3/spl times/ for maximum delay and a lower bound of -1/spl times/ for minimum delay can be proven. Efficient Newton-Raphson iteration is also proposed as a technique for computing the Miller factor or effective capacitance. This result is highly applicable to crosstalk coupling delay calculation in deep submicron gate-level static timing analysis. Detailed analysis and approximation are presented. SPICE simulations are demonstrated to show high correlation with these approximations. |

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.
