| Abstract | Traditional placement problems are studied under a fully specified cell library and a complete netlist. However, in the first, e.g., 2 years of a 2-3 year microprocessor design cycle, the detailed netlist is unavailable. For area and performance estimation, layout must nevertheless be done with incomplete information. Another source of incompleteness comes from reuse of instances from earlier design generations; these instances and their parameters will change as the project evolves. The problem of placement with incomplete data (PID) can be abstracted as having to place a circuit when p/sub c/% of the cells and p/sub n/% of the nets are missing. The key challenge in PID is how to add missing cells and nets. In this paper, two "patching-methods" for adding missing nets and cells are proposed. The methods are called abstraction and fusion. Experimental results are very interesting and illustrative. First, they show that PID is a difficult problem and an arbitrary (and perhaps intuitively sound) method may not produce high-quality results. Experiments verify that the abstraction method is a very good predictor and that fusion is not because circuits produced by abstraction attain much of the properties of the original circuits. Summary Table 3 in Section 4 shows that when a circuit has 10% incompleteness, abstraction can predict the final total wirelength with an error of 5.8%, while fusion has a 67.8% error in predicting the wirelength in the same circuit. |

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.
