Digital Systems Testing and Testable Design: The Path to High-Quality Solutions
Aiming for 99% or higher for stuck-at faults. Digital Systems Testing and Testable Design: The Path
Digital testing is the process of verifying that a physical device—whether it’s a microprocessor, an FPGA, or an ASIC—is free from manufacturing defects. Unlike design verification, which ensures the logic is correct, manufacturing testing looks for physical flaws like "stuck-at" faults, bridges, or timing delays caused by the fabrication process. Building a high-quality digital system requires a symbiotic
Building a high-quality digital system requires a symbiotic relationship between design and test. By integrating advanced DFT structures and leveraging sophisticated ATPG tools, companies can ensure that their silicon is not only innovative but also reliable and cost-effective. In a world where failure is expensive, testable design is the ultimate insurance policy. A high-quality testing flow relies heavily on
A high-quality testing flow relies heavily on . ATPG software analyzes the netlist and automatically creates the mathematical patterns needed to achieve maximum fault coverage. A "high-quality" solution in this context means:
