Ensuring Excellence: Digital Systems Testing and Testable Design Solutions

In the era of System-on-Chip (SoC) and billion-transistor integrated circuits, the cost of failure extends far beyond financial loss—it impacts brand reputation, safety, and system reliability. As semiconductor technology nodes shrink and design complexity skyrockets, traditional testing methods have become insufficient. Achieving high quality in digital systems now requires a paradigm shift from merely "testing for defects" to "designing for testability."

High-quality testing doesn't stop at the chip level; it extends to the Printed Circuit Board (PCB). Boundary scan allows for testing the interconnects between chips without using physical probes, ensuring that the assembly process is just as flaw-free as the silicon itself. The Impact on Quality and Bottom Line Die-to-Die (D2D) interconnect test via parallel or serial

• Die-to-Die (D2D) interconnect test via parallel or serial PHYs.
• Known Good Die (KGD) testing – each die must be fully tested before assembly.
• Post-bond test with limited thermal budget.

Conclusion

The relationship between design and testing is symbiotic. Without testable design principles, high-quality testing is impossible due to a lack of access. Without high-quality testing, testable design is meaningless because defects go undetected. Conclusion The relationship between design and testing is
