I have a physics background but not an EE background. I found verilog pretty easy to grasp. VHDL took me a lot longer.

To get some basic ideas I always recommend the book code by charles petzold: https://www.amazon.com/Code-Language-Computer-Hardware-Softw...

It walks you through everything from the transistor to the operating system.

(Apparently I need to add that I work for AWS on every message so yes I work for AWS)
