Abstract | We present a noise-driven effective capacitance method for estimating the combined propagation noise and crosstalk noise. Gate propagation noise rules are efficiently calculated inside the Ceff procedure to determine a linear Thevenin model of the victim driver. A voltage-dependent current source model (Croix and Wong, 2003 and Keller et al.,2004) of the driver, along with a load capacitor is analyzed to generate the gate output waveform, from which noise rules are directly extracted. This method removes potential errors introduced in traditional look-up table or fitted-equation based noise rules. The linear driver Thevenin model can then be employed to analyze the propagation noise, while the same Thevenin resistance can be used to analyze the crosstalk noise. The combined coupling and propagation noise can then be estimated using superposition. In this work, we extend the popular timing-driven effective capacitance method into the noise domain. Similar to the effective capacitance method in timing analysis, this technique can successfully separate the nonlinear driver analysis from the linear interconnect analysis. In addition, the linear driver model can significantly ease the task of finding the worst-case peak alignment among all the victim and aggressor noise sources. Experimental results on both RC and RLC nets from industry designs show both accuracy and efficiency compared to SPICE results. |

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.
