Digital Systems Testing And Testable Design Solution -

Uses a Linear Feedback Shift Register (LFSR) to generate pseudo-random patterns to test the logic gates. C. Boundary Scan (IEEE 1149.1 / JTAG)

When chips are soldered onto a Printed Circuit Board (PCB), testing the connections between them is difficult. JTAG provides a standard "boundary" around the chip's pins, allowing engineers to test board-level interconnects without using physical probes. 4. Automatic Test Pattern Generation (ATPG) digital systems testing and testable design solution

Design verification (checking if the design is correct) and manufacturing testing (checking if the hardware was built correctly) are two different worlds. Even a perfect design can suffer from physical defects like shorts, opens, or CMOS imperfections during fabrication. Uses a Linear Feedback Shift Register (LFSR) to
