On this page

    Section goal

    NoC topology, AXI/ACE contracts, coherency ordering, and contention-aware integration debug.

    How to study this section

    1. Start with the topic hub to learn the integration contract.

    2. Use mechanism and reports pages to connect contract to metrics.

    3. Use debug and worked-example pages for war-room readiness.

    4. Close with checklist and PPA impact before closure signoff.

    Topics

    1. noc-topology-and-qos/ — NoC Topology & QoS

    2. axi-ace-contracts/ — AXI/ACE Contracts

    3. coherency-ordering-integration/ — Coherency & Ordering Integration

    4. fabric-contention-debug/ — Fabric Contention Debug

    Reports and artifacts

    • NoC contention heatmap

    • ordering violation report

    • QoS fairness summary

    • protocol trace

    Mini case study

    Bandwidth looked fine at average load, but p99 tail violated SLA due to arbitration starvation.

    Debug branches

    • Isolate traffic class

    • Check ordering assumptions

    • Audit arbitration policy

    Senior review question

    Ask: what baseline, owner, and artifact prove this topic is truly closed?
