It's hard to find an accessible generalist course on the topic, since it's so niche, but you might take a look at Bill Buzbee's Magic-1 - https://www.homebrewcpu.com/ - which does have schematics and a write- up on the microarchitecture, although like most of these projects he's taking things from the logic level up and not digging too much into the nitty-gritty at the borderline of the analog & digital domains. https://www.nand2tetris.org/book is one I'm still reading through; it's very accessible, but even hand-wavier on the "magic," unfortunately.
