I’m Arunachalam, an Electronics and Communication Engineering student with a focused interest in VLSI ⚙️, RTL design 🧩, FPGA development ⚡, and embedded systems 🔧. I’m driven by a genuine curiosity to understand how hardware behaves beyond abstractions—how signals propagate, how timing constraints shape design, and how a system evolves from a conceptual block diagram into a functioning implementation.

My learning process is centered around a structured engineering cycle: simulate → observe → debug → refine → build. I enjoy examining digital systems from both functional and timing perspectives, using HDL-based design to express hardware behavior with clarity and precision.

I’m currently strengthening my foundation in digital logic, RTL architecture, synthesis workflows, timing analysis, and system-level design. Whether I’m refining an RTL module, troubleshooting a waveform, or developing an embedded application, I aim to create solutions that are technically sound, efficient, and thoughtfully engineered.
