Can you imagine a VLSI Engineer with Zero Knowledge of CMOS? Zero Knowledge of Electrons and Holes? Zero Knowledge of 4-bit Adder? Zero Knowledge of Channel Length of a MOS? V, as in voltage, at which point OR voltage difference in the "V=IR" equation? This is the situation of Electronics Engineers and Companies are forced to hire such candidates. #B.Tech. #VLSI Vs B.Tech EC- how differently will we teach students so that they can understand the difference between positive ions and holes in B.Tech VLSI ? #NEP Vs. Existing Education Policy - What is the difference in that if college is same, management is same, stalf is same, their teaching pattern is same? #Free #EDA tools vs. paid EDA tools - what is the use of a government initiative to provide the EDA tools to colleges when they don't know how to use them? #NAAC ranking A Vs D - what's the difference if it's all on paper and just Infra? #phd vs #MTech degree of Lecturer - How will it impact if they don't know what's the application of the subject they are teaching? Students Running Behind Packages and missing knowledge - how the whole eco-system is going to work? A lots of questions in my mind, and I am not able to find the ANSWER to these .. CAN ANYONE HELP ME?? I wanted to tag a lot of people here, but I don't want to target individuals. But I am expecting an Answer from everyone. We are saying it's improving - but frankly speaking it's going in negative direction and this is all done by us only.

#LinuxForVLSI: Why It Matters for Chip Designers?? In the VLSI world, tools like Synopsys, Cadence, and Mentor Graphics run on Linux. Knowing how to work with Linux isn't optional-it's essential. Here’s how Linux is used in EDA tool workflows: ✅ Workspace Navigation – Engineers manage large HDL projects using command-line navigation for faster access. ✅ Editing & Debugging – Quick edits to Verilog/SystemVerilog files, constraints, and simulation scripts are done right in the terminal. ✅ Tool Setup – Before running tools, environment variables and paths are configured using shell commands. ✅ Simulation & Log Analysis – Engineers search simulation logs for errors/warnings using Linux tools instead of scrolling manually. ✅ Remote Access – EDA tools run on remote Linux servers; engineers connect securely and run jobs from anywhere. ✅ Automation – Shell scripting automates regression, synthesis runs, and other repetitive tasks. 🎯 Want to grow in RTL or DV? Get hands-on with Linux - it's your best ally in chip design! #VLSI #LinuxForVLSI #ChipDesign #RTL #SystemVerilog #EDA #Semiconductor #DV #LinuxSkills #Cadence #Synopsys #TheSiliconSandbox

10 must-know CMOS fundamentals questions for VLSI freshers (Interview-ready) If preparing for VLSI roles (design/verification/STA/PD), mastering CMOS basics is a huge differentiator. Here are 10 high-impact, conceptual questions interviewers love to ask freshers—plus what they’re really testing. 1.     Explain how a CMOS inverter works. ·       What happens in different input regions (0, transition, VDD)? ·       Why is CMOS static power ideally near zero? ·       What sets the switching threshold? 2.    Draw and explain the DC transfer characteristics of a CMOS inverter. ·       Define VIH, VIL, VOH, VOL and noise margins. ·       Where is the region of highest gain and why? 3.     What are the main sources of power consumption in CMOS? ·       Dynamic (switching + short-circuit), static (leakage types). ·       How do frequency, capacitance, and VDD impact power? ·       Practical ways to reduce each component. 4.    What is logical effort? ·       How it helps size gates for speed. ·       Parasitic delay vs effort delay; path effort intuition. ·       When not to trust it blindly. 5.     Explain body effect and its impact on VTH. ·       Why source-to-body matters (especially in bulk). ·       How it affects speed, leakage, and corners. ·       Differences in bulk vs SOI/FinFET contexts. 6.    Setup and hold time: what, why, and how violations occur. ·       Metastability and permissible timing windows. ·       Typical fixes (add pipeline, skew, sizing, Vt swap). 7.     Short-channel effects: DIBL, velocity saturation, channel length modulation. ·       How scaling changes I-V behavior and VTH. ·       Impact on delay, noise margins, leakage. 8.    What is PVT variation? How do corners affect design? ·       Process (SS/TT/FF), voltage, temperature. ·       Why timing closure needs best/worst corners and derates. ·       On-chip variation basics. 9.    Design a 2-input CMOS NAND (or NOR): transistor sizing and reasoning. ·       Series vs parallel stacking impact on pull-up/pull-down strength. ·       Matching rise/fall delays and W/L ratios conceptually. 10.  Explain the trade-offs between low-Vt, standard-Vt, and high-Vt cells. ·       Speed vs leakage vs IR/EM vs variability. ·       Multi-Vt strategies in real chips (critical vs non-critical paths). How to use this: ·       Don’t just memorize definitions—tie each question to waveforms, curves, or simple sketches. ·       Practice explaining in 60–90 seconds with clarity and structure. ·       If possible, connect answers to a small project or lab (e.g., “I measured inverter VTC and extracted noise margins…”). Also happy to mock interview for VLSI freshers. #VLSI #CMOS #Semiconductors #Freshers #Design #ASIC #FPGA #STA #PhysicalDesign #FrontEnd #BackEnd #EDA #Interviews
