Boundary scan is a method for testing interconnects (wire lines) on printed circuit boards or sub-blocks inside an integrated circuit. Boundary scan is also widely used as a debugging method to watch integrated circuit pin states, measure voltage, or analyze sub-blocks inside an integrated circuit. The Joint Test Action Group (JTAG) developed a specification for boundary sc… WebThe built-in-self test (BIST) is an 8-bit field, where the most significant bit defines if the device can carry out a BIST, the next bit defines if a BIST is to be performed (a 1 in this …
