Modern System-on-Chip (SoC) designs often include billions of transistors, multiple clock domains, embedded memories, and high-speed interfaces. As complexity grows, ensuring that chips can be effectively tested after fabrication has become a critical part of the VLSI design process.<\/span><\/p><p><span style=\"font-weight: 400;\">This is where Design for Testability (DFT) plays a vital role.<\/span><\/p><p><span style=\"font-weight: 400;\">DFT techniques allow engineers to detect manufacturing defects and ensure chip reliability before products reach customers. However, implementing and verifying DFT structures requires powerful Electronic Design Automation (EDA) tools.<\/span><\/p><p><span style=\"font-weight: 400;\">For engineers planning a career in VLSI testing, learning the right DFT tools is essential.
