In the first half of 2025, both Samsung Electronics' DS division and SK Hynix did not recruit any semiconductor circuit design personnel.
As a result, I have realized that many Bachelor's and Master's students preparing for semiconductor circuit design are feeling anxious.

I took classes on circuits and PCBs in school, but after taking this course, I realized that what is learned in the field is definitely different. It was great for understanding the workflow because it followed the exact methods used in actual companies, from technical meetings and component selection to datasheet analysis. The explanations are easy to understand even for those who are new to HW design.
When I first encountered PCB design through self-study, I thought it was just a matter of connecting lines. However, through this lecture, I was able to perfectly establish the organic relationship between schematic design and artwork (layout). In particular, the biggest takeaway was learning how to perform "reasoned design"—such as analyzing the block diagrams and power systems in STM32 datasheets to understand why crystals and decoupling capacitors are essential, and why checking ESD tables is necessary. It was incredibly beneficial because it didn't just teach me how to use the tools; it allowed me to experience the actual professional workflow, from strategic pin mapping using CubeMX to setting up a JTAG debugging environment. Now, I have the confidence to design my own circuits without being intimidated by complex datasheets. Thank you for teaching me so thoroughly!
Hello. I am a student who took your course when it first opened last year. I joined a defense industry SME before graduation and am currently working in the HW team. Even when compared to actual field work, I feel that this course was incredibly helpful. I believe it is the best lecture in that it allows you to experience the basic knowledge and the entire flow of HW design. Of course, there is a vast amount of content to study in detail, and I still have much more to learn, but I think it would have been very difficult to start working without having taken this course. Thank you.
I am working as a defense industry HW engineer, and I really liked this lecture because it organizes the basics and practical requirements well for learning. Although the tools used vary by company, the basic concepts are the same, making this an excellent lecture. I think it would also be great to use as training material for new hires at the company.
This was the first lecture where I learned about PCBs. I liked that the course covered everything in detail, from theory to practical processes, and helped me gain a clearer understanding through assignments and feedback along the way! I highly recommend this course to those learning PCB design for the first time or those who want to learn HW design from a practical perspective!
