I am learning to design PCBs, and while I have a basic understanding of the components (viz. resistors, diodes, transistors, etc) as the board gets populated with more components, (consider, for instance, an arduino dev board), it is just very challenging to build a model of how the entire board works - the logic etc.

Further, a good part of modern microcontroller boards is dedicated to (I think), power delivery and conditioning.

Getting a functional model / representation of the entire board in my head has been a huge, as yet insurmountable, challenge.

Are there any good games that can help me wrap my head around these concepts?
