.... Because we are sorrounded by so many good people.

Remain thankful to all of you!

It gives me immense pleasure to express my sincere thanks and gratitude to all those who have kindly helped me in carrying out this research work. I am very much thankful to Prof. Virendra Singh, IIT Bombay and Prof Matthew Jacob for their guidance throughout the research. From the very beginning of my Ph.D. days, Prof. Matthew and Prof. Singh have been guiding me in all the aspects of my research. I am particularly thankful to Prof Virendra Singh for he has kindly welcomed me to IIT Bombay and ensured my stay and research in every visit to CADS laboratory. Prof Matthew has been constantly monitoring my progress which helped me pursue the research even when I used to feel moral weakness. Prof. Matthew has provided me several technical inputs although my research area is slightly different than his usual area of interest, the inputs have latter resulted in the publications.
Prof. Matthew has been very much accommodating in various situation particularly for my visit to IIT Bombay. I am thankful to MHRD, Govt. of India and Indian Institute of Science for supporting my entire research by institute scholarship.

It was my pleasure to share and discuss some our ideas with Prof Shankar Balachandran, IIT Chennai. I respect his quick ideas and suggestions, many of our work got good shape partly because of his suggestions.

Prof Kewal Saluja of the University of Wisconsin for all of our works has given many valuable suggestions and reviewed our ideas on Joint-scan architecture. In the starting of this work Prof. Saluja has given us a good motivation to look into the architectural aspect of Joint-scan. Prof Janak Patel, University of Illinois, UC, used be our frequent guest at CADSL, IIT Bombay. Many of our ideas which sprung from our daily meeting are strengthen by Prof. Janak Patel. He often boosts our moral in pursuing research with engineering attitude. Prof Janak has taught us how by taking care of minor aspects of research work, the larger problem gets a better understanding. 

During my stay at IISc, I have met with some of the fine professors whose words are filled with inspirations and encouragements. I thank Prof Y Narahari for his support in each and every difficulty of my IISc research life. Prof Narahari is one of the professors who understands the student's di culty
from the rst person perspective. Prof M Narasimha Murthy has always helped me and ensured my timely research and completion of the thesis. I am very much thankful to the current chairman of our department Prof. Jayant Haritsa for he has always pushed me for early completion of the thesis, Professor has officially ensured all of my visits to IIT Bombay for research to happen in fast track.

I would like to acknowledge the help I got from the technical staff member of ALTERA laboratory at Department of Electronic System Engineering, IISc in using Synopsys and other CAD tools. I also would like to thank my colleagues at VLSI Design laboratory, EE, IIT Bombay for providing me access to Synopsys and Cadence tools. I acknowledge the collaborative work with LSI Logic where we could perform several experiments on peak power issues.
Many of my friends have contributed to our research work. I am extremely thankful to my co-authors who have actually experimented with many of our ideas. My colleague Deepak Malani has contributed in several aspects of our work on worst power estimation. Thanks to Alok Malakar for conducting a lot of experiments on  flip-flop design, building libraries, doing place and routing of the proposed architecture. Thanks to Binod and Nehru for exploring and experimenting on Dynamic and Bombay scan. Our friend Satyadev has done a work for which I am really thankful to him. We have
designed a set of  flip-flops for high performance and low power scan test. Thanks to Rohini and Nihar for extending the work on worst power estimation. I am thankful to Suryakant Ji and Toral madam for their constant support in several technical diffi culties. Our research atmosphere has always been kept vibrant by several of my friends at CADSL, I thank Newton Singh, Prashant, Sandipan, Nitant, Karthik, Virat, and Vijay for always keeping me encouraged in doing research of some or other kind.

IISc campus has always been a place of quest. Though I am an ordinary researcher but my friends have always kept my quest alive for knowing the laws and principles of Nature. I thank Hrishikesh, Ramesh, Ashish, Thulasi Raman, Ramana Reddy, Govind, Dipti Bhai, Tanuj, Rahul, and other friends  for helping me on several occasion for several reasons. We have always cherished the discussions on the topic which great scientists sometime feel reluctant to discuss. Especially I thank to Ramesh and Ashish for sparing time for me to make me understand the CAD tools and the detail concept of VLSI technology.

Staying in Bangalore has always been pleasant for me. The due goes to my senior brothers of Bhaktivedanta Institute, Bangalore who have always provided me an opportunity to explore the diff erent horizon of life.

The love and care that I have received from my parents can not be acknowledged formally, those are priceless. I pray to the lord Jagannatha that may I ever serve them and keep them in a happy life.

Saying is that without the mercy of supreme lord even a blade of grass does not move. Lord, you are the great, may your greatness be always echoed in my mind.

PS: This is acknowledgment for the thesis which I submitted recently to the Computer Science Department at IISc, Bangalore.

Dear Suvrata Prabhuji

Unable to sustain my sorrow and disturbance on hearing the departure of one of my inspiring friends and professors! Prof. Subhash Mishra has been serving in Mechanical Engineering department at IIT Guwahati. His research contribution is phenomenal, number of publications, number of students, academic responsibilities, and other services to the research community in his field are indeed inspiring. The most beautiful side of his life is his service to Bhaktivedanta Institute, Kolkata in several roles. Prof. Mishra has been long associated with the Bhaktivedanta Institute, Kolkata since his first meeting with a sober saint of modern time His Holiness Bhaktiswarupa Damodara Swami (also known as Dr. T D Singh in the academic community) during his Ph.D. time at IIT Kanpur. Keeping his research contribution aside, when we look into his personal life, we find that he is, as a professor, truly a role model for the students.

It is a great good fortune for me that I have got an opportunity to serve Bhaktivedanta Institute, Kolkata under the guidance of Prof. Mishra. In our spiritual circle, we call him as Subrata Prabhuji. We have served together for many of the AISSQ conferences, which is an annual students' conference of Bhaktivedanta Institute, Kolkata, initiated by His Holiness Bhaktiswarupa Damodara Swami. All those moments are very much fresh and clear still now in my mind. In all those services, whatever I could render a bit, is due to Prof. Mishra (Suvrata Prabhuji). From a very small, minute things like how to talk, how to receive a guest, how to compose a mail to how we can do an excellent research being a great spiritualist at the same time, he has taught me a lot many things. In all those process and services he has been ever inspiring to me keeping my enthusiasm always maintained.

I met Suvrata Prabhuji during the preparation for AISSQ 2012 conference at IISc Bangalore. He has been leading the AISSQ conference series as a chairman. As the conference was nearing we have a lot many things to complete, which are with several uncertainties. Many of the things are just half done. We have to talk with the professors at IISc for several amenities, related to conference venues and accommodation of the speakers etc. Apart from that, we also have to meet the professors/speakers and finalize their arrival, accommodation, travell etc. And at the same time we have our personal things like doing early morning sadhana and attending to research/class etc. In midst of all those packed services, Suvrata Prabhuji was very much confident and clear about the execution of plan and its success. His frequent sentence used to be "Jaynarayan don't worry, Krishna will take care". Suvrata Prabhuji is really a charming person, never could anybody see any disappointment in his face. It really surprises me that despite all those services, he would ensure to read Bhagavad Gita, do his meditation, and must sit for yoga. Prabhuji is a great reader of Bhagavad Gita, he would chant the slokas time to time to bring the things in position and perspective. He is indeed an exemplary personality for me. I remember Suvrata Prabhuji also delivered an inspiring lecture at Choksi Hall, IISc on Thermodynamic of Life. He shared his experience on how he recovered from the first serious brain tumor and could become completely alright. However, the unseen plan of providence came for the second time.

Whenever he comes to IISc or Bangalore he would definitely call for me. It has been a great pleasure for me to accompany him to meet and interview professors on science and spirituality. In one occasion we met a

chemistry Nobel laureate at NIAS, IISc Bangalore. Suvrata Prabhuji interviewed him, discussed several issues in modern society. We had also a discussion on how by synthesizing the science and spirituality such problems can  be eradicated. Prabhuji then discussed about the role of Bhaktivedanta Institute with Professor. We then gifted him a "Seven Nobel Laureate on Science and Spirituality" book to the Professor. Prof. Suvrata Prabhuji always go with complete preparation and plan. He taught me how to stand and talk when you meet a senior and respected person, how to keep things ready before the meeting, and what are the important things to discuss.

It is a great loss for many of us. For Bhaktivedanta Institute surely none of us can replace him in his role. I pray to Srila Sripada Bhaktiswarupa Damodara Maharaj, Dear Srila Sripada Maharaj, we have heard from sages that the eternal relationship between a disciple and his spiritual master is glorious. Dear Sripad Maharaj, you have always taken care of each of us, Suvrata Prabhuji now would be surely rendering a devotional service of your choice.

Dear Suvrata Prabhuji, we will be missing you, however, we will never let you go way from our heart. 

Hare Krishna!
