| Abstract | This paper addresses the problem of efficiently and accurately generating two-vector tests for crosstalk induced effects, such as pulses, signal speedup and slowdown, in digital combinational circuits. These effects are becoming more prevalent due to short signal switching times and deep submicron circuitry. These noise effects can propagate through a circuit and create a logic error in a latch or at a primary output. We first present a new way for predicting the output waveform produced by an inverter due to a non-square wave pulse at its input. Our modeling technique captures such properties as the amplitude of a pulse and its rise/fall times and the delay through a device. To expedite the computation of the response of a logic gate to an input pulse, we have developed a novel way of modeling such gates by an equivalent inverter. We have developed a mixed-signal test generator that incorporates classical PODEM-like static values as well as dynamic signals such as transitions and pulses, and timing information such as signal arrival times, rise/fall times, and gate delay. We also present a new analog cost function that is used to guide the search process. Comparison of results with SPICE simulations confirms the accuracy of this approach. This paper focuses primarily on crosstalk induced pulses, but these results have been extended to deal with speedup and slowdown effects. |

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.
