The testing power is the biggest VLSI chip testing as the testing power is ver functional power which affects the reliability paper low test power architecture is propose pattern in one scan chain serially and the re loaded parallel by the serial scan chain one a proposed technique is very effective in test p the serial shifting happens only in one scan ch the switching activity in other scan chains. Fro conducted on ISCAS89 benchmark circuits, th power architecture reduces the test powe additional test cycles.
