Abstract: PURPOSE: A method for selecting the test point by using the timing loop-up table in a BIST structure is provided to improve the fault coverage of built in self test(BIST) structure used for testing the inner logic of chip. CONSTITUTION: A method for selecting the test point by using the timing loop-up table in a BIST structure includes the steps of: calculating(S102) the timing during the insertion of test point for the all nodes in the timing path; calculating(S104) the cost for the node of path having a slack being smaller than the slack base value by comparing the slack calculated in the timing path with the slack base value; calculating(S105) the fault coverage by performing the fault simulation after a number of test points are inserted by aligning the calculated cost in descending order; and repeating(S106) the above steps until the fault coverage(FC) becomes larger than the fault coverage(FCset) by comparing the fault coverage(FC) obtained from the fault simulation with the predetermined fault coverage(FCset).
