Why it matters: I3C blends high-speed data with tight timing rules. PurVue embeds a real-time oscilloscope inside the analyzer workflow so engineers can see protocol and PHY behavior together—cutting debug cycles for sensors, MCU hubs, and mobile designs.
1) Embedded real-time oscilloscope
PurVue captures analog waveforms alongside protocol events. You can spot overshoot, ringing, or marginal rise times right where arbitration or HDR commands occur.
2) Protocol + PHY correlation
Markers align decoded I3C traffic with eye views, letting you tie NACKs or timing violations directly to signal integrity issues instead of guessing.
3) Deep buffering for bursts
Extended memory keeps long captures intact—useful for multi-sensor bursts, hot-join sequences, or vendor-specific command flows.
4) Flexible triggering
Trigger on protocol conditions (e.g., HDR enter/exit, hot-join) and on analog thresholds to catch rare glitches that only show under certain load states.
5) Automation hooks
Script captures and pass/fail checks to integrate I3C validation into CI pipelines. Reuse test lists across firmware drops to block regressions.
Primeasure POV
- Correlate PurVue captures with scope-based eye/jitter on critical nets (SDA/SCL) to confirm margins before board release.
- Baseline hot-join timing across temperature corners; log analog markers with decoded events for reproducibility.
- Add automated alarms for SDA/SCL rise/fall limits so marginal boards are flagged early.
