Table
| Test ID | Category | Objective | Method | Pass Criteria |
|---|---|---|---|---|
| TVP-001 | Visual / Assembly | Confirm assembly correctness | Inspect polarity, orientation, solder, ePad wetting | No assembly defects |
| TVP-002 | Power Rails | Verify 3.3 V hub rail | Measure VDD33 / VDDA33 during startup and steady state | 3.0 V to 3.6 V and stable |
| TVP-003 | Reset Timing | Verify RESET_N behavior | Scope 3.3 V rail and RESET_N | RESET_N held low until supply valid; meets timing |
| TVP-004 | Clock | Verify 24 MHz startup | Probe clock/crystal behavior with suitable technique | Clean oscillation or valid external clock |
| TVP-005 | Upstream Attach | Verify host detection | Connect to host and monitor enumeration | Hub enumerates reliably |
| TVP-006 | Port Enumeration | Verify each downstream port | Test one device per port sequentially | Each enabled port enumerates |
| TVP-007 | Multi-port Operation | Verify simultaneous operation | Enumerate devices on all enabled ports | All intended ports work together |
| TVP-008 | High-speed Path | Verify HS-capable signaling | Use HS-capable device(s) and host | High-speed operation achieved where expected |
| TVP-009 | Suspend / Resume | Check suspend behavior | Host suspend/resume cycles | Expected behavior observed and documented |
| TVP-010 | Power Cycle | Verify cold start robustness | Repeated full power cycles | No boot failures across sample set |
| TVP-011 | Hot Plug | Verify user attach/detach | Repeated plug/unplug on each port | No latch-up, no false OC, reliable detection |
| TVP-012 | Over-current | Verify port fault response | Force/simulate over-current per safe fixture method | Port power is removed and fault is reported |
| TVP-013 | VBUS Delivery | Verify downstream VBUS | Load each port to intended current | Voltage remains in allowed range |
| TVP-014 | Battery Charging | Verify charging-port behavior if enabled | Attach BC1.1-compatible sink/load | Port behavior matches intended design |
| TVP-015 | EMI / ESD Smoke Test | Early robustness screen | Bench-level pre-compliance test | No permanent damage, no functional upset beyond recovery plan |
| TVP-016 | Detach/Reattach Corner Case | Validate errata-related behavior | Exercise fast detach/reattach or device self-reset cases | Behavior understood and acceptable |
| TVP-017 | EEPROM / SMBus Config | Verify programmed configuration if used | Read back behavior through enumeration and test hooks | Config matches expected descriptors and features |
| TVP-018 | Thermal | Check temperature rise | Operate worst-case port load and measure temperatures | Within component limits and design targets |
