As circuits became denser, internal nodes became buried deep within the logic, inaccessible to external testing probes. This made it impossible to verify if a specific transistor was functioning correctly using only external inputs and outputs.
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.
