Hi! I’m whoashish115, and this is my personal Semiconductors, Electronics & Embedded Systems wiki.
I built Siligen to keep everything I learn about semiconductors, electronics, and embedded systems in one place—from semiconductor physics, analog and digital electronics, microprocessors, microcontrollers, embedded programming, real-time systems, FPGA and HDL design, computer architecture, VLSI, PCB design, signal processing, communication systems, sensors, robotics, and everything in between. Along the way, I also collect mathematical foundations, datasheet notes, circuit analyses, implementation guides, code snippets, hardware projects, research papers, design references, tools, and small insights that I don’t want to forget. Instead of searching the internet for the same concepts repeatedly, I can simply come back here.
If you’re visiting for the first time, I’d recommend starting with the sidebar navigation. Everything is organized by topic, making it easy to explore semiconductor devices, circuit theory, analog electronics, digital logic, embedded C/C++, ARM architecture, RISC-V, RTOS, FPGA development, Verilog, VHDL, VLSI, PCB design, power electronics, communication systems, signal processing, control systems, robotics, IoT, hardware debugging, design tools, datasheets, research papers, projects, and more.
Most of these notes are written for my future self, but if they help you understand a circuit, design a PCB, implement firmware, build an embedded system, read a datasheet, or discover something new, that’s even better. Siligen is a living knowledge base that will continue to grow as I learn, experiment, design, and explore the ever-evolving world of semiconductors, electronics, and embedded systems.
