Structural analysis proves the reset network is built correctly; simulation proves it behaves correctly when resets actually move. Most functional testbenches hold reset once at time zero and never touch it again, which leaves mid-operation assertion, partial resets, and release ordering completely untested. These four lessons close that gap.
Lesson | After it you can... |
|---|---|
Name what ordinary tests miss about reset behaviour. | |
Write directed and randomised reset scenarios with a self-checking testbench. | |
Write assertions for safe outputs, quiet release, and cleared state. | |
Ask the coverage questions that prove reset scenarios ran. |
Because structure cannot show behaviour under real sequences: reset asserted mid-operation, partial resets, release ordering, and recovery after reset need a running design, not just a correct netlist.
