Taking AIMS at Digital Design [EPUB ebook] 
Analysis, Improvement, Modeling, and Synthesis

This is an introductory textbook for courses in Synchronous Digital Design that enables students to develop useful intuitions for all of the key concepts of digital design. The author focuses this tutorial on the design flow, which is introduced as an iterative cycle of Analysis, Improvement, Modeling, and Synthesis. All the basic elements of digital design are covered, starting with the CMOS transistor to provide an abstraction upon which everything else is built. The other main foundational concepts introduced are clocked synchronous register-transfer level design, datapath, finite state machines and communication between clock domains.
