If there are billions of transistors in a CPU, there is no chance that somebody designed every single one of them manually. Is their layout calculated or something?

It’s a lot of copy and paste, honestly. You layout a small section that can be replicated many times. You can then do a schematic to layout comparison via an automatic routine to make sure everything is hooked up right. You couldn’t check every connection by sight, it’d take too long.
