Testing a sequential circuit (which has memory) is converted into testing a combinational circuit (which is easier). The four-phase process is:

Measuring the steady-state supply current. A high current draw in a CMOS circuit often indicates a bridge or short, even if the logic appears to function correctly. Finding the Right "Solution" A high current draw in a CMOS circuit

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)

The ease with which the logic value of internal nodes can be driven to the primary output pins to be measured. digital systems testing and testable design solution

Standard D flip-flops are replaced with "Scan Flip-Flops" featuring an internal multiplexer.

BIST moves the external Automatic Test Equipment (ATE) functionality directly onto the silicon, enabling the chip to test itself at functional clock speeds (At-Speed testing).
