Digital Systems: Testing And Testable Design Solution High Quality Updated

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.

Without a robust testing strategy, defective chips reach the consumer, leading to: Brand damage. Digital testing is the process of verifying that

Reducing the number of patterns to lower the "Time on Tester," which directly reduces manufacturing costs. which ensures the logic is correct

This puts the tester inside the chip. Logic BIST (LBIST) and Memory BIST (MBIST) allow the device to test itself at full clock speed, which is essential for detecting "at-speed" defects that slow testers might miss. defective chips reach the consumer
