The zyBooks Approach

Less text doesn’t mean less learning.

An exceptionally hands-on approach to presenting digital design by combining theory and practice, including various web-based simulators, like a circuit simulator, finite-state machine simulator, high-level state machine simulator, datapath simulator, and more, plus numerous tools, like a Boolean algebra tool, a K-map minimizer tool, etc. The material emphasizes a top-down behavior-to-circuits approach, for combinational, sequential, and high-level (register-transfer-level) design. Emphasis is placed on RTL design, where most modern digital design occurs. This material’s HDL (Verilog and VHDL) coverage is intentionally template focused, teaching just enough of the HDLs to understand the templates.

“The most striking aspect of ZyBooks for me as an instructor has been the ability to introduce a topic and then point my students to specific exercises/activities in ZyBooks that would not only expound on the concept but allow them to practice them with confidence.”
