Abstract | This work presents a layout synthesis tool for analog integrated circuits called Aladin. The layout generation is based on relatively complex sub-circuits rather than non-optimal single devices. A flexible module generator environment is developed for designers to write and maintain technology and application independent module generators for sub-circuits. A two-stage placement technique is proposed, which dramatically improves the placement accuracy without compromising the efficiency compared with the one-stage placement. The analog module routing consists of two phases including global routing and detailed routing. The minimum-Steiner-tree based global routing can be integrated into the placement procedure improve the routability of placement solutions. The compaction based constructive detailed routing finally realizes the layout of the whole circuit. The benefit of Aladin providing layouts comparable to expert manual ones is demonstrated with several existing tools. |

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.
