   The separation of manufacturing and design processes in the integrated circuit industry to tackle the ever increasing circuit complexity and time to market issues has brought with it some major security challenges. Chief among them is IP piracy by untrusted parties. Hardware obfuscation which locks the functionality and modifies the structure of an IP core to protect it from malicious modifications or piracy has been proposed as a solution. In this paper, we develop an efficient hardware obfuscation method, called Mystic (Mystifying IP Cores), to protect IP cores from reverse engineering, IP over- production, and IP piracy. The key idea behind Mystic is to add additional state transitions to the original/functional FSM (Finite State Machine) that are taken only when incorrect keys are applied to the circuit. Using the proposed Mystic obfuscation approach, the underlying functionality of the IP core is locked and normal FSM transitions are only available to authorized chip users. The synthesis results of ITC99 circuit benchmarks for ASIC 45nm technology reveal that the Mystic protection method imposes on average 5.14% area overhead, 5.21% delay overhead, and 8.06% power consumption overheads while it exponentially lowers the probability that an unauthorized user will gain access to or derive the chip functionality.

2. Practical Skills for Students in Mechatronics and Robotics Education

   Berry, C. ; Gennert, M. ; Reck, R. ( June 2020 , ASEE annual conference exposition proceedings)

   In September 2019, the fourth and final workshop on the Future of Mechatronics and Robotics Education (FoMRE) was held at a Lawrence Technological University in Southfield, MI. This workshop was organized by faculty at several universities with financial support from industry partners and the National Science Foundation. The purpose of the workshops was to create a cohesive effort among mechatronics and robotics courses, minors and degree programs. Mechatronics and Robotics Engineering (MRE) is an integration of mechanics, controls, electronics, and software, which provides a unique opportunity for engineering students to function on multidisciplinary teams. Due to its multidisciplinary nature, it attracts diverse and innovative students, and graduates better-prepared professional engineers. In this fast growing field, there is a great need to standardize educational material and make MRE education more widely available and easier to adopt. This can only be accomplished if the community comes together to speak with one clear voice about not only the benefits, but also the best ways to teach it. These efforts would also aid in establishing more of these degree programs and integrating minors or majors into existing computer science, mechanical engineering, or electrical engineering departments. The final workshop was attended by approximately 50 practitioners from industry and academia. Participants identified many practical skills required for students to succeed in an MRE curriculum and as practicing engineers after graduation. These skills were then organized into the following categories: professional, independent learning, controller design, numerical simulation and analysis, electronics, software development, and system design. For example, professional skills include technical reports, presentations, and documentation. Independent learning includes reading data sheets, performing internet searches, doing a literature review, and having a maker mindset. Numerical simulation skills include understanding data, presenting data graphically, solving and simulating in software such as MATLAB, Simulink and Excel. Controller design involves selecting a controller, tuning a controller, designing to meet specifications, and understanding when the results are good enough. Electronics skills include selecting sensors, interfacing sensors, interfacing actuators, creating printed circuit boards, wiring on a breadboard, soldering, installing drivers, using integrated circuits, and using microcontrollers. Software development of embedded systems includes agile program design, state machines, analyzing and evaluating code results, commenting code, troubleshooting, debugging, AI and machine learning. Finally, system design includes prototyping, creating CAD models, design for manufacturing, breaking a system down into subsystems, integrating and interfacing subcomponents, having a multidisciplinary perspective, robustness, evaluating tradeoffs, testing, validation, and verification, failure, effect, and mode analysis. A survey was prepared and sent out to the participants from all four workshops as well as other robotics faculty, researchers and industry personnel in order to elicit a broader community response. Because one of the biggest challenges in mechatronics and robotics education is the absence of standardized curricula, textbooks, platforms, syllabi, assignments, and learning outcomes, this was a vital part of the process to achieve some level of consensus. This paper presents an introduction to MRE education, related work on existing programs, methods, results of the practical skills survey, and then draws conclusions based upon these results. It aims to create the foundation for standardizing the development of student skills in mechatronics and robotics curricula across institutions, disciplines, majors and minors. The survey was completed by 94 participants and it was clear that there is a consensus that the primary skills students should have upon completion of MRE courses or a program is a broader multidisciplinary systems-level perspective, an ability to problem solve, and an ability to design a system to meet specifications.

3. Engaging Students in Exploring Computer Hardware Fundamentals Using FPGA Board Games.

   Ramirez-Salgado, A. ; Hossain, T. ; Hoque, T. ; Bhunia, S. ; Koroly, M. J. ; Davey, B. ; Antonenko, P. ( June 2023 , 2023 ASEE Annual Conference & Exposition)

   Electronic devices have become indispensable in everyone’s life and so the computer hardware industry is demanding skilled professionals to design and physically implement devices to satisfy the market. However, misconceptions surrounding manufacturing jobs and the increasing initiatives to motivate students with engineering majors to focus on software-related topics such as artificial intelligence and blockchain are hindering students’ interest in hardware computing. Our project, funded by the NSF’s Improving Undergraduate STEM Education (IUSE) program, addresses the need to engage more students in explorations (and, eventually, design) of computer hardware by developing a set of games played on an easy-to-use hardware platform to understand and implement the fundamental concepts that are essential to modern computing systems (Figure 1). To encourage flexible and broad adoption, the games are conceived as standalone units within a curriculum design that leverages equitable pedagogical practices, experiential learning, and inquiry-based learning to cultivate engineering identity and persistence using situational interest and self-efficacy theories. We aim to offer the curriculum as an elective undergraduate course for all engineering majors at two US institutions and also research and evaluate the feasibility of implementing it as a summer program with high school students. Each module in the curriculum is divided into 5 phases: activation of prior knowledge, mini-lesson, gameplay, student-led work time, and debriefing. The games support collaboration rather than competition, and each lesson is tagged with equity spotlights, including Universal Design for Learning (UDL) and Culturally Sustaining Pedagogies (CSP) principles. Finally, informed by the Technological Pedagogical Content Knowledge (TPACK) framework, each lesson includes a teacher implementation guide and teacher educative materials to facilitate implementation (Figure 2). We have tested the first two games in the curriculum for usability and feasibility with a group of high school students. The topics of these games include binary arithmetic and Boolean logic gates. Participants were challenged to solve tasks using the hardware tools at their disposal. This usability and feasibility testing study provided us with important design and implementation implications.

4. Workshops for Building the Mechatronics and Robotics Engineering Education Community

   Gennert, M. ; Lotfi, N. ; Mynderse, J. ; Jethwani, M. ; Kapila, V. ( June 2020 , ASEE annual conference exposition proceedings)

   Intelligent Autonomous Systems, including Intelligent Manufacturing & Automation and Industry 4.0, have immense potential to improve human health, safety, and welfare. Engineering these systems requires an interdisciplinary knowledge of mechanical, electrical, computer, software, and systems engineering throughout the design and development process. Mechatronics and Robotics Engineering (MRE) is emerging as a discipline that can provide the broad inter-disciplinary technical and professional skill sets that are critical to fulfill the research and development needs for these advanced systems. Despite experiencing tremendous, dynamic growth, MRE lacks a settled-on and agreed-upon body-of-knowledge, leading to unmet needs for standardized curricula, courses, laboratory platforms, and accreditation criteria, resulting in missed career opportunities for individuals and missed economic opportunities for industry. There have been many educational efforts around MRE, including courses, minors, and degree programs, but they have not been well integrated or widely adopted, especially in USA. To enable MRE to coalesce as a distinct and identifiable engineering field, the authors conducted four workshops on the Future of Mechatronics and Robotics Engineering (FoMRE) education at the bachelor’s degree level. The overall goal of the workshops was to improve the quality of undergraduate MRE education and to ease the adoption of teaching materials to prepare graduates with a blend of theoretical knowledge and practical hands-on skills. To realize this goal, the specific objectives were to generate enthusiasm and a sense of community among current and future MRE educators, promote diversity and inclusivity within the MRE community, identify thought leaders, and seek feedback from the community to serve as a foundation for future activities. The workshops were intended to benefit a wide range of participants including educators currently teaching or developing programs in MRE, PhD students seeking academic careers in MRE, and industry professionals desiring to shape the future workforce. Workshop activities included short presentations on sample MRE programs, breakout sessions on specific topics, and open discussion sessions. As a result of these workshops, the MRE educational community has been enlarged and engaged, with members actively contributing to the scholarship of teaching and learning. This paper presents the workshops’ formats, outcomes, results of participant surveys, and their analyses. A major outcome was identifying concept, skill, and experience inventories organized around the dimensions of foundational/practical/applications and student preparation/MRE knowledgebase. Particular attention is given to the extent to which the workshops realized the project goals, including attendee demographics, changes in participant attitudes, and development of the MRE community. The paper concludes with a summary of lessons learned and a call for future activities to shape the field.

5. A hybrid NDN-IP Architecture for Live Video Streaming: A QoE Analysis

   https://doi.org/10.1109/ISM52913.2021.00032  

   Dasgupta, Ishita ; Shannigrahi, Susmit ; Zink, Michael ( November 2021 , IEEE International Symposium on Multimedia (ISM))

   With live video streaming becoming accessible in various applications on all client platforms, it is imperative to create a seamless and efficient distribution system that is flexible enough to choose from multiple Internet architectures best suited for video streaming (live, on-demand, AR). In this paper, we highlight the benefits of such a hybrid system for live video streaming as well as present a detailed analysis with the goal to provide a high quality of experience (QoE) for the viewer. For our hybrid architecture, video streaming is supported simultaneously over TCP/IP and Named Data Networking (NDN)-based architecture via operating system and networking virtualization techniques to design a flexible system that utilizes the benefits of these varying internet architectures. Also, to relieve users from the burden of installing a new protocol stack (in the case of NDN) on their devices, we developed a lightweight solution in the form of a container that includes the network stack as well as the streaming application. At the client, the required Internet architecture (TCP/IP versus NDN) can be selected in a transparent and adaptive manner. Based on a prototype we have designed and implemented maintaining efficient use of network resources, we demonstrate that in the case of live streaming, NDN achieves better QoE per client than IP and can also utilize higher than allocated bandwidth through in-network caching. Even without caching, our hybrid setup achieves better average bitrate over live video streaming services than its IP-only alternative. Furthermore, we present detailed analysis on ways adaptive video streaming with NDN can be further improved with respect to QoE.
