We are pleased to announce that our PhD group lead by Prof Anand Bulusu at Indian Institute of Technology, Roorkee ECE Department IIT Roorkee has published a paper titled "Switching Activity Factor-Based ECSM Characterization (SAFE): A Novel Technique for Aging-Aware Static Timing Analysis," which has been accepted for publication in the Transactions on Computer-Aided Design of Integrated Circuits and Systems. I am a co-author of this work. In this paper, a SAFE (Switching Activity Factor-based Effective Current Source Model) for aging-aware static timing analysis (STA), a new technique for estimating the timing performance of digital circuits. SAFE is based on the development of device-level variation-aware analytical timing models of stacked and multistage logic cells (commonly employed transistor topologies in a synthesized netlist of a random logic path), which drastically reduces the recharacterization efforts of the standard cells. The models developed are derived as a function of input transition time (TR) and load capacitance (CL). I congratulate Lomash Chandra Acharya Acharya for taking the initiative and putting up the extream effort, for publishing this intriguing and interesting paper.

Great Interview by Prof. Ramgopal Rao (Group Vice Chancellor BITS Pilani & Ex-Director IIT-Delhi) Few Take Home Messages from the Interview 1. Although India's publication record has increased tremendously in the last two decades ( we are # 3 in the rank), our rank in the global innovation index is 40. This data suggests that the new knowledge that we generate does not translate into social/economic benefits. 2. He also talks about his struggle in starting a company and his efforts to scale up 3. Having worked on technology development, academia-industrial collaboration, IP, and start-ups for the last ten years, I can relate to some of his frustrations. I think one of the main reasons why India is not doing well in innovation is because "the research output" is only measured in the number of papers other activities such as technology development, academia-industrial collaboration, IP, and start-ups are not considered that important and hence there is little incentive for people to work on this. 4. Unless there is a policy change at the government/institute level to recognize that technology development, academia-industrial collaboration, IP, and start-ups are as important as publications things will not change. #startup #deepscience #deeptech #ip #patents #industry-academiapartnership #technologydevelopment #viksitbharat #economicbenefit #socialimpact https://lnkd.in/dRRApkMX

Dr.Mothilal L.
While IITs are often seen as prestigious institutions with excellent career prospects, a recent viral post by an IIT student has sparked a critical conversation. The student shared his disillusionment, citing a lack of enthusiasm, subjective grading systems, and insufficient placements. Many students have echoed these sentiments, highlighting issues like harsh grading, inadequate research facilities, and intense pressure. Anand Kumar Yadav, who dropped out of IIT Bombay and IIT Roorkee, mentioned bleak placement scenarios and subpar research facilities. Other students, including those from IIT Delhi and IIT Kharagpur, spoke about the variability in grading systems and the competitive, often stressful environment. Moreover, when institutions are misgoverned with corruption and insensitive faculty, chaos, and confusion are camouflaged under additional stress for students. This has led to serious mental health issues, including rising suicide rates among students. It's crucial to address these systemic issues to ensure that the entire educational setup is corrected from systemic faults that plague institutions with undesirable activities and fathomless corruption.

CO2 Sequestration [Viscous-Fingering; Capillary-Fingering] 1. Are we critically deciding the resultant phase (gas/liquid/super-critical) of injected CO2 into the formations (deep saline aquifers; depleted oil/gas reservoirs; unminable coal seems) – ‘solely’ as functions of aquifer/reservoir temperature and pressure? Or ‘CO2 storage capacity’ will be also taken into account? 2. Following the injection of CO2 into saturated subsurface formations, CO2 would try to displace the existing pore fluids that remain to be more viscous than the injected CO2. If so, then, to what extent, Capillary Number and Viscosity Ratio would try to define the resulting displacement pattern of the immiscible fluids, if (a) Velocity of the invading fluid keeps changing with space and time? (b) IFT between CO2 and brine keeps fluctuating significantly? (c) Contact angle of brine on a substrate associated with a drainage condition remains varying? (d) Viscosity values of CO2 and brine keep varying significantly with time and space? How easy would it remain to measure IFT and contact angle of brine on rock surface – surrounded by gaseous/liquid/super-critical CO2 - @ field conditions – towards obtaining Capillary number and Viscosity ratio? 3. How do we have a control over - capturing the combination of viscous and capillary forces @ field-scale that would essentially dictate the resulting displacement pattern (viscous-fingering/capillary-fingering/stable displacement)? How exactly to delineate the phase-boundaries for the respective displacement pattern – with varying pore-size distribution and aquifer geometry? With evolving aquifer/reservoir pore-geometry, whether, Capillary fingering would only occur under a relatively lower CO2 injection rates, irrespective of Viscosity ratio? 4. As the viscosity of CO2 being lesser than brine (viscous fingering develops during CO2 injection as the viscosity values of gaseous, liquid and super-critical CO2 generally remain to be orders of magnitude smaller than brine viscosity @ field pressure/temperature conditions), following viscous fingering, whether CO2 – by default – would flow through the least resistive pathways – in the absence of sweeping the most of the brine, which remains located out of the least resistive or preferential pathways? In such cases, how easy would it remain to deduce the resultant displacement efficiency (as a function of Capillary number and viscosity ratio)? Feasible to control CO2 flow pattern in order to obtain maximum displacement efficiency? Or CO2-water foams be used to attain stable-displacement and to enhance brine sweeping? How exactly to deduce the displacement ratio (which involves CO2 saturation after breakthrough) – in transition zones (the crossover zone between capillary-fingering and viscous-fingering; or, between viscous-fingering and stable-displacement) @ field-scale?

Feels great to see our paper, entitled "Shesha : Multi-head Microarchitectural Leakage Discovery in new-generation Intel Processors", authored by Anirban Chakraborty, Nimish Mishra, Debdeep Mukhopadhyay, accepted at USENIX 2024, which is one of the top venues in Computer Security. Recent years have seen our computer architectures being attacked by Transient execution attacks, which often exploit speculations (or mis-speculations by processors) for enhancing performance. While largely these discoveries are based on manual inspections, in this work, we develop an automated framework named Sesha, inspired by Particle Swarm Optimization, which exhibits faster convergence rates than state-of-the-art fuzzing techniques for automatic discovery of transient execution attacks. The tool has helped to unearth new attacks which were unreported so far. We hope this tool from Secured Embedded Architecture Laboratory, IIT Kharagpur, will not only help security experts but also computer architects to develop better and secured processor architectures. The acceptance synchronizes very well with the end of my year long and fruitful visiting tenure at NYU Abu Dhabi, time to go back to KGP!

I got in touch with Prof. V Ramgopal Rao from Birla Institute of Technology and Science, Pilani to understand India's semiconductor mission. The Indian government has been very clear and focussed about its semiconductor mission, which was launched in 2021. Currently, India is the second largest importer of semiconductor chips globally after a 92% increase in chip imports in the last three years. “Given our infrastructure and the lack of ecosystem for semiconductor supplies, companies hesitate to venture into this field in India. A semiconductor foundry also requires many auxiliary industries such as semiconductor grade gases and chemical supplies, which are not present in India," he said. Though there are a number of designing and manufacturing companies in India, there is no foundry. Despite several semiconductor startups present in Bengaluru, manufacturing still happens in other countries. The present government is making significant efforts to woo the semiconductor players with massive subsidies. These subsidies can easily go to over 50%. Increasing interest from semiconductor companies and joint partnerships with Indian companies may eventually help India achieve its target of capturing 10% of the world’s semiconductor market by 2030. “For design, India is already a global powerhouse”. he said. He also believes that the reason India hasn’t built something like a Tesla is because of a lack of collaboration with academia. Despite a thriving automotive industry, “Nobody wants to take mechanical engineering or study other automotive subjects in the country because there aren’t any decent paying jobs. This is a result of lack of innovation and lack of collaborations between industry and academia." “It took OpenAI tens of billions of dollars to make ChatGPT. The research funding in India is so tiny,” he added. For AI, there is a dire need for a massive number of GPUs. Indian universities barely have the necessary infrastructure for AI research. Meanwhile, the total amount of research funding that Indian universities receive, China spends on just two universities. The government’s hesitation to invest more in research is due to the low base of research spending, coupled with bureaucratic hurdles in spending allocated funds. This vicious circle hampers innovation and research in India, but unfortunately, it’s a topic that receives little attention. Ease of doing research, is something that needs to be carefully evaluated for these funding schemes to be effective, he added. He said that investing so much in a country where the infrastructure is not up to the global standards is a challenge for big companies.

How will you respond ? if I tell you that Physics is simpler than Biology? Yes, it's easier. Physics is based on a magical learning process. Let me explain it to you using three pointers: ~ Structured Learning Process: Physics has an organized learning process that moves from one approach to the next, which makes it appear more effortless than different topics in biology. ~ Unified Learning: The subject is learned in a unified manner, where fundamental principles apply across different topics, providing a complete understanding. ~ Mastering Basics: Mastering basics is the most important part of understanding physics, such as understanding cross-products will make a solid foundation for understanding complex concepts like torque, angular momentum, conservation of angular momentum, etc. In conclusion, while both physics and biology have their complexities, one can find physics to be simpler due to its structured learning process, unified way of learning, and focus on mastering basics. By embracing this magical learning journey, physics will become more accessible and easier to comprehend.

Our recent papers on page migration in Hybrid DRAM-PCM memories. Hybrid memory systems with a combination of DRAM and Non-Volatile Memory (NVM) types can make use of scalability and performance of both NVM and DRAM. Random placement of pages in Phase Change Memory (PCM) with more write accesses incurs higher write latencies. So, migrating write intensive pages from PCM to DRAM helps to reduce execution time and memory response time for applications. However, to take advantage of this idea, the pages have to be migrated at the correct time during execution. In addition we need to take care of on-going memory accesses. Our recently published two papers address these issues: (1) We give a QoS aware migration method that increases the chances of higher accesses to the migrated candidate pages; at the same time keeping regular service rate optimal. The work appears in the Journal of Systems Architecture. Title: "Migration-aware slot-based memory request scheduler to guarantee QoS in DRAM-PCM hybrid memories" Authors: Aswathy N S and Hemangee Kapoor (2) Identifying the migration candidate page normally depends on the access count. However, we observe that the temporal behaviour of the page is more important than its accumulated access count. In addition, if the page is not migrated within a give time frame, the benefits wil reduce. Towards this we propose a write intensity based migration method that also reverts the decision in case there are delays in migration. The work appears as an invited book chapter from the VLSI-SoC conference, published by Springer Nature Computer Science series. Title: "A Leap of Confidence: A Write Intensity aware Prudent Page Migration for Hybrid Memories" Authors: Aswathy N S, Aishwarya Gupta and Hemangee Kapoor

Paper Title Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications Authors Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India Abstract Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data. Keywords Signal to Noise Ratio (SNR), Bit Error Rate (BER), mm-Wave, MIMO, NOMA, deep learning, optimization.

We successfully enabled another batch of May for developing embedded software. My target is to enable at least 100 engineers within a year through live sessions and encourage them to support each other in future. I have now teaching experience of six years. Recently many working folks from Robotics and Drone making companies also joined to learn bits in detail. I had experience of product based companies in India but now I learned many things related to service based companies. We will start June batch tomorrow. The premium kit May batch will move to now Linux development and project phase. Based on my total 30 yrs experience , I suggest new generation to work on 1: Coding skills 2: Debugging skills 3: Soft skills 4: Networking with Industry folks 5: Keep adding technology words in your dictionary. Take help of ChachaG ( Hope you understood😊) to learn more. Sink , Source, Volatile , Dangling , Wild , Weak , IPC, TLB, Kill, Segmentation, Fragmentation, Hole, Leak, ICMP, Half Adder etc. 6: Try to learn various architectures along with C . *Does 8051 support long long ? *What is size of long in x86 ? *What is size of long in x86-64 ? * What is size of long long in STM32 * There is long int but why not long float ? * How to find size of int without sizeof() ? “𝑰𝒇 𝒚𝒐𝒖 𝒕𝒉𝒊𝒏𝒌 𝒚𝒐𝒖 𝒄𝒂𝒏 𝒅𝒐 𝒊𝒕, 𝒐𝒓 𝒚𝒐𝒖 𝒕𝒉𝒊𝒏𝒌 𝒚𝒐𝒖 𝒄𝒂𝒏’𝒕 𝒅𝒐 𝒊𝒕, 𝒚𝒐𝒖 𝒂𝒓𝒆 𝒓𝒊𝒈𝒉𝒕.” – 𝑯𝒆𝒏𝒓𝒚 𝑭𝒐𝒓𝒅 Have a Great Day ! #embeddedsystems #embeddedc #microcontroller #microcontrollers #embedded #embeddedsystem #embeddedlinux #freertos #firmware #firmwareengineer #firmwarejobs #devicedriver #softwareengineers #electronics #embeddedjobs #embeddedengineer #embedkari #indiajobs #careers #jobs #opentowork #openings #hiring #work #freshers

Doing more with less is what I have gotten into these days. I have seen BOM and demands coming to me/my team in TBs of storage and GBs of Memory and nearly half a dozen cores of 1-2Ghz. Today I am developing software for systems with less than 4MB of storage, 320KB of memory and two cores giving me 80Mz. Embedded systems and IOT were part of a magical world for me until few months ago. Simple things like back light of an LCD screen on a panel going off after few seconds, clock ticking away on the microwave, the beep when I turn on/off the fan or aircon, all were expected behaviour. Now that I am doing it myself, I am having the Chuck Nolan moment of having made his fire at that island. Coming from a time when 16Mz PC-AT using 640kb of memory and 1.44 even 360kb floppy disks was luxury, I see my current hardware is way superior to in early 90s. I used to juggle memory then through overlay files and TSRs, creating linked lists as and when I see need to store/purge data. INT21H was my thing for event driven coding. HiMem the one beyond 640kb I used it as RAMDisk which is like blazing fast drive. Brings back memories. The world of embedded systems hardware and the ecosystem has matured to a point where I am seeing otherwise heavy HTTPS, gRPC and Node.js implementation seen possible in such tiny bit of hardware. Host to Host API calls, is just few lines of code away. The capability of a platform like Espressif which gives BLE, WiFi with station and AP mode to coexist, it's ability to interface a ton of peripherals it's amazing. These have been around for years, I at times feel - where was I? Who knows, or one day AI systems which rely on blazing fast GPU hardware may even find its way into these tiny nano scale hardware. May be it already has also. #embeddedsystems #iot #domorewithless
