V. Veena, Prabhu E., and Mohan, N., “Improved Test Coverage by Observation Point Insertion for Fault Coverage Analysis”, 2019 3rd International Conference on Trends in Electronics and Informatics (ICOEI). 2019.[Abstract]


Design for testing implies on adding an extra hardware to circuit under test so that the difficulty in testing the circuit becomes easy and large number of faults can be detected to increase the test coverage of the circuit. In a circuit there might be a large number of faults and some fault in the circuit will have high controllability as well as observability those faults will be very difficult to detect. A new approach has been introduced which involves the insertion of observation points at most suitable location to capture the most difficult to observe faults which facilitate structural testing for both on-chip and off-chip for better fault coverage. Insertion of the observation point into the internal part of the circuit enables direct observation of the internal part of the circuit. The observation points are inserted at those locations where observability is high and the occurrence of fault at those location makes the faults hard to propagate to the output.

A. Ravikumar, Mohan, N., and Dr. Soman K. P., “Performance Enhancement of a Series Active Power Filter using Kalman Filter based Neural Network Control Strategy”, in 2018 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2018.[Abstract]


Increased use of power electronic converters at various stages of power system is the main cause of harmonics and reactive power. Presence of harmonics adds pollution to the power system or degrades the quality of power. A series active power filter is used to reduce the harmonics and also compensate reactive power. This paper explores the use of a Kalman filter based neural network controller for enhancing the operation of a three phase series active power filter which is connected at the input of a non-linear load. The entire experiment has been conducted in MATLAB/Simulink environment. It is observed that there is substantial reduction in harmonics with this proposed control scheme. The three phase total harmonic distortion in the non-linear load circuit has been reduced from 33.63% to 2.61%.

N. Mohan, Krishnan, M., S. Rai, K., Mathu, M. M., and Sivakalyan, S., “Efficient Test Scheduling for Reusable BIST in 3D stacked ICs”, in 2017 International Conference on Advances in Computing, Communications and Informatics, ICACCI 2017, 2017, vol. 2017-January, pp. 1349-1355.[Abstract]


VLSI testing is essential with advancing technology as it helps improve yield and enables the detection of faulty chips after manufacturing. The factors which play important roles are the power dissipation and time taken during the process of testing. BIST, Built-In Self-Test is a testing technique which enables the device to test itself. A reusable BIST is proposed which allows the usage of the same BIST for pre-bond and post-bond testing. The proposed BIST is used for testing 3D stacked ICs. Test scheduling is a critical problem that is faced while 3D stacked ICs are tested as the same tests which are performed during prebond might need to be performed simultaneously or so during post-bond. Here, we propose a modified Skyline algorithm to obtain an improved test schedule. The algorithm is tested on the inputs from ISCAS-85 benchmark circuits. The obtained results are compared with the results from traditional Skyline algorithm.

N. Mohan and Dr. Anita J. P., “A zero suppressed binary decision diagram-based test set relaxation for single and multiple stuck-at faults”, International Journal of Mathematical Modelling and Numerical Optimisation, vol. 7, pp. 83-96, 2016.[Abstract]


This paper presents a new zero suppressed binary decision diagram (ZBDD)-based approach for obtaining larger number of relaxed bits. These test sets find major application in reducing the power consumed during testing. Experiments performed on single and multiple stuck-at faults using ZBDDs show better results in terms of percentage of relaxation over the existing comparable BDD-based approaches. Moreover using these relaxed test vectors and by suitable X-filling methods average switching activity (ASA) of the circuit can be reduced, which will reduce the power dissipation during testing.

B. D. Kumar Reddy and Mohan, N., “N-Detect Test Pattern Generation And Relaxation Using ZDD”, International Journal of Electrical, Electronics and Data Communication, vol. 2, no. 7, p. Online-Ressource, 2014.[Abstract]


Manufacturing test is a major challenge for very-deep submicron (VDSM) integrated circuits. Mandated productquality levels must be ensured by screening all defective devices before they are shipped. However, defect screening remains a formidable problem, especially for VDSM process technologies, since it is impossible to explicitly target every possible defect. This paper mainly deals with a method to generate N-detect test sets that provide high defect coverage making judicious use of new pattern quality metrics which is basically depended on the concept of ZDD. Simulation results for benchmark circuits show that, this method provides higher fault coverage and coverage ramp-up compared to other methods using BDD as ZDD provides an efficient way of solving problems expressed in terms of set theory and cube vectors.
