Design For Test (DFT) Services

Apex’s DFT solution is a cutting-edge and cost-effective service optimized for your design.

Our DFT service provides a comprehensive methodology for inserting test structures into a design and integrating existing test structures embedded in IP. We automate test structure insertion and design analysis, minimizing the number of required modifications or perturbations to the front-end design. The Apex DFT flow is completely integrated with all other parts of the Apollo design flow and provides a cohesive test solution that delivers high coverage.
