Combinational vs. sequential digital circuits (continued)
Sequential systems exhibit behaviors (output values) that depend not only on the current input values, but also on previous input values
In reality, all real circuits are sequential because the outputs do not change instantaneously after an input change
- why, and why is it then sequential?
A fundamental abstraction of digital design is to reason (mostly) about steady-state behaviors
- what are the outputs after sufficient time has elapsed for the system to make its required changes and settle down
