If you're building or integrating Automated Test Equipment for aerospace or defence electronics, the technical requirements go well beyond "does the test pass." You need documentation that satisfies MIL-STD, AS9100, and DO-178C auditors — and an architecture that scales from prototype to production. Here's how modern Universal ATE systems are structured for defence-grade compliance. The Core Architecture A defence-grade ATE system has four functional layers: ┌─────────────────────────────────────────┐ │ Test Executive (LabVIEW) │ ← Orchestrates all test sequences ├────────────────┬────────────────────────┤ │ Instrument │ DUT Interface │ ← Hardware layer │ Control │ (ICT/JTAG/Func) │ ├────────────────┴────────────────────────┤ │ Data Management Layer │ ← Logging, traceability, reports ├─────────────────────────────────────────┤ │ Calibration & Verification │ ← Ensures measurement accuracy └─────────────────────────────────────────┘ Test Executive Design in LabVIEW The test executive controls the sequence, manages results, and handles failures. Key design principles: Test Sequence: 1. DUT identification (serial number scan or manual entry) 2. Pre-test self-check (verify instrument calibration status) 3. ICT phase — passive component verification 4. JTAG boundary scan — IEEE 1149.1 interconnect verification 5. Power-on functional test — operational verification 6. RF/signal analysis — if applicable to DUT type 7. Report generation — automatic, timestamped 8. Pass/fail disposition record JTAG Integration via IEEE 1149.1 For high-density boards where bed-of-nails is not viable, JTAG boundary scan is implemented via a JTAG controller (e.g., XJTAG, Corelis, or ASSET InterTech) integrated into the LabVIEW environment: LabVIEW → JTAG Controller API → Scan Chain → DUT ICs The boundary scan description files (BSDL) for each IC define the test vectors. Your test executive loads BSDL files, generates scan chain topology, and runs interconnect tests automatically. Data Traceabili
