Abstract | The performance of modern integrated circuits is significantly influenced by coupling effects of interconnects. Crosstalk noise must therefore be analyzed in the early stage of design to develop reliable VLSI interconnects. In this paper, we present a closed form crosstalk noise estimation technique to coupled RLC interconnects based on coupled transmission line theory and Fourier series analysis. The salient features of our model include accuracy, computational efficiency and continuous time domain solution. We analyze the impact of finite resistance in coupled RLC interconnects. The nonlinear behavior of the driver (CMOS inverter) is captured well in the proposed model. We introduce a novel technique to model CMOS inverter, namely MRLM (Multiple Ramp Library Model). It replaces the nonlinear driver into its equivalent RC model. The resultant circuit resembles with the simple coupled RLC interconnect in the absence of inverters and hence the same analysis is extended after the replacement. Based on our continuous time defined models, we derive analytical models for delay and energy dissipation due to interconnect. In addition, this work emphasizes on improving the performance namely computational efficiency. Simulations of our analytical models and SPICE are demonstrated by assuming different sets of line parameters. It is shown from the numerical results that our estimates match closely with that of SPICE simulations at a mean estimation error of 2.25 percentage. |

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.
