METHOD AND APPARATUS FOR SYSTEM TESTING USING SCAN CHAIN DECOMPOSITION

摘要

to test some of the blood testing system through the scan chain of the blood test systems method are provided. The method includes the step of executing the instruction set for testing a part of the step, and the blood test system for generating a set of instructions for testing a part of the step, the blood test system to break down the scan chain into a plurality of segments . Yirwojimyeo scan chain into a plurality of elements, each segment includes at least one of the elements of the scan chain. The instruction set includes a plurality of instruction processors and a plurality of test instructions concerning ISA (Instruction Set Architecture). Test instructions may include at least one of a scanning operation to be performed on the segments on each of a plurality of segments of the scan chain. ;
