Protocol Checkers & Assertion Strategy

Section goal

SVA and procedural checkers, temporal protocol rules, error-injection validation, and debug strategies for high-signal protocol closure.

This section trains how to reason from traffic behavior to VIP mechanism, then close with owner accountability, reliability gates, and release-safe decisions.

How to study this section

1. Start with each topic hub and draw the mechanism path.

2. Use reports and debug pages to prove causality before tuning.

3. Practice worked examples and interview drills with explicit evidence chains.

4. Close each topic with checklist and silicon impact pages.

Concept diagram

VIP SECTION - Protocol Checkers & Assertion Strategy

testcase -> agents -> checkers -> coverage -> evidence

Metric graph

checker noise vs real violations trend

Reports and artifacts

• checker hit report

• coverage closure sheet

• compliance trace matrix

• regression health snapshot

Mini case study

A profile drift caused false checker storms until configuration hashes were locked in CI.

Debug branches

• Reproduce with locked seed and profile

• Isolate checker vs scoreboard vs DUT paths

• Map failure to spec clause and owner

Senior review question

Ask: which latency, bandwidth, and reliability evidence proves this VIP topic is closed under real traffic?
