My Thoughts on ASIC PD Interviews: A 10-Year Perspective - Part 2

Part 2. Fundamentals Matter

In the highly specialized and constantly evolving field of semiconductor engineering, a profound and unshakeable understanding of fundamental principles is not merely advantageous, but absolutely essential. During our recent interview processes, we were consistently and notably impressed by candidates who demonstrated an exceptional ability to articulate and elucidate complex concepts with clarity and precision. This included a deep dive into topics such as the intricate operational mechanics of a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), the foundational principles governing Complementary Metal-Oxide-Semiconductor (CMOS) logic design, and the critical nuances of timing analysis in integrated circuits.


These are not simply abstract academic subjects to be memorized and recited; rather, they serve as the indispensable building blocks upon which all real-world engineering solutions are constructed. From the design of microprocessors and memory chips to the development of advanced sensors and power management units, these fundamental concepts underpin every aspect of semiconductor device creation and application. Therefore, for any individual aspiring to a technical role within this industry, it is absolutely imperative to ensure that your foundational knowledge is robust and unequivocally solid.


The emphasis here is not on rote memorization of formulas or equations, but on a much deeper, intuitive comprehension. It's about genuinely understanding the underlying physics, the design trade-offs, and the interdependencies that dictate how and why these intricate systems function the way they do. This includes grasping the behavior of electrons and holes in semiconductor materials, the impact of various doping concentrations, the implications of gate dimensions, and the intricate interplay of capacitance and resistance in circuit performance. A candidate who can not only recite a definition but also explain the practical implications of a parameter change, or debug a theoretical problem based on these fundamentals, demonstrates the kind of critical thinking and problem-solving skills that are invaluable in this demanding profession. True mastery lies in the ability to apply these concepts to novel challenges and innovate solutions that push the boundaries of what is possible in semiconductor technology.

    This resonates deeply. The more I work in this field, the more I realize that true problem-solving power comes from mastering the basics. Fund-a-mental is the answer.

A Wider Perspective on Chips, Code, and AI

Ever since I was a kid, I've been fascinated by the magic of technology. Not the stage-magic kind, but the real, tangible magic that happens when you etch impossibly small patterns onto a slice of silicon, or when you write lines of code that spring to life, learning and creating in ways we're only beginning to understand. For me, taking apart an old radio wasn't just about seeing the components; it was about trying to grasp the invisible logic that connected them. That curiosity never left. It led me down a rabbit hole that became a career, a path that has placed me right at the intersection of hardware and software engineering. I've spent years with one foot in the cleanroom, marveling at the physics of semiconductor fabrication, and the other foot in the command line, crafting the software that breathes intelligence into that silicon. I’ve come to see these two worlds not as separate disciplines, but as two sides of the same revolutionary coin. And that's why I...

LLM as of now

Ref: https://blog.arcbjorn.com/state-of-llms-2025 In the late-2025 landscape of Large Language Models (LLMs), the era of a single, dominant AI model has conclusively ended. Instead, we are now in a specialized ecosystem where different models excel at specific tasks. This shift, as detailed in the blog post "State of LLMs in Late 2025," has led to a more diverse and competitive market, with users needing to understand the key technical differentiators between models to select the right tool for their needs. These differentiators include the model's architecture, the data it was trained on, and its fine-tuning methods. The major players in the LLM space of late 2025 each have their own strengths and ideal use cases. OpenAI's GPT-5 is noted for its unified intelligence system, making it a versatile and powerful option for a wide range of applications. Anthropic's Claude Sonnet 4.5 has established itself as the leader in coding and autonomous tasks, a go-to for devel...
