Ask HN: Where to learn about semiconductors design?

You can start 40 years ago at the source https://en.wikipedia.org/wiki/Mead%E2%80%93Conway_VLSI_chip_...

Lynn Conway 'Introduction to VLSI Systems' https://ai.eecs.umich.edu/people/conway/VLSI/VLSIText/PP-V2/...

One semester course based on this book, or rather the other way around - book based on notes Lynn Conway made while preparing the course https://ai.eecs.umich.edu/people/conway/VLSI/EDN/The%20VLSI%..., was enough for people to start designing real useful chips, like Jim Clark (SGI) Geometry Engine https://ai.eecs.umich.edu/people/conway/VLSI/ClassicDesigns/...

Learn VHDL and/or Verilog

Questions like this almost always need context.

What is your current level of technical understanding? What do you want to achieve through your learning? What do you mean when you say "semiconductor design?"
