Ensure your products are test-ready with smarter design, higher coverage, and fewer late-stage surprises
Design for Testability & Predictive Coverage
Design for Testability & Predictive Coverage
We offer end-to-end DFT engineering and coverage optimization services including:
- Testability Audits
Comprehensive reviews of schematics, layout, and BOM to identify test constraints and improvement opportunities. - DFT Guidelines & Implementation
Design recommendations for improving test point access, isolation, scan chain coverage, and diagnostic visibility. - Predictive Fault Coverage Modeling
Simulated analysis of achievable coverage based on netlist, layout, and proposed test strategies. - Boundary Scan Integration
Optimization of JTAG topology, isolation devices, and instruction register handling for efficient scan testing. - Fixture Strategy & Test Point Reduction
Minimize fixture costs and complexity by maximizing shared probe use, via access, and virtual probing methods.
At Arxtron Technologies, our Design for Testability (DFT) and Predictive Coverage services are focused on enabling smarter product design with embedded testability, ensuring cost-effective and scalable testing across the product lifecycle.
By integrating test strategy early into the design phase, we help manufacturers achieve higher fault coverage, reduce fixture complexity, and minimize NPI-to-production risks. Leveraging our deep expertise in functional, in-circuit, boundary scan, and hybrid test environments, we deliver actionable insights and implementation support that improves test economics and product quality.
Applications & Use Cases
Our DFT and predictive coverage consulting is ideal for high-complexity, high-reliability product categories, including:
- Automotive ECUs, ADAS modules, infotainment & BMS
• Medical-grade electronics such as patient monitors and diagnostics
• Industrial control systems, PLCs, and IoT sensors
• Aerospace & defense electronics with strict compliance needs
• Consumer devices with tight cost and time constraints
From early-stage schematics to final test deployment, we optimize your product for inspection, access, and validation.
