Properties and SVA

What a proof engine does with an assertion: monitors, sampling, Boolean history forms, safety versus liveness, and debugging the properties themselves.

  • 4topics
  • 16lessons

Every proof in this course is a question about an assertion: can its failure state be reached? This section teaches SVA only as the proof engine reads it. The language itself lives in the SystemVerilog course; here each textbook operator is translated into the Boolean history form the proof front end accepts, and every rule is shown passing on a correct design and failing on a mutant.

Topic

What it covers

After it you can...

SVA as a Formal Tool Reads It

Monitors, sampling, delay pipelines and the translation table

Turn any textbook rule into a runnable Boolean history check.

Implication, Edges and Windows

Overlapped versus non-overlapped, level versus edge, stability, history windows

Place every check in the right cycle and window.

Safety, Liveness and What a Tool Can Say

Safety versus liveness, weak and strong, bounded response, fairness

Classify a rule and say what result a proof can honestly give.

Debugging and Reviewing Assertions

Reading failures, vacuity, mutation checks, the review checklist

Prove that a property can fail before trusting its pass.

Suggested order: top to bottom. The first topic builds the monitor picture and the translation table everything else relies on; the second fixes the one-cycle errors reviewers find most often; the third draws the line between what is provable and what needs a bound; the fourth turns that scepticism into a review routine. Readers chasing one failure can start at its topic and follow the links back.

Top-down diagram: the design registers and the property monitor feed one product model, which feeds the proof question whether the fail state can fire, which yields either proven or a counterexample.
A design and its property monitor form one product model; the proof asks whether the monitor can reach its fail state.
