| Abstract: | As series boundary scan topology can not address the test access port controller,which leads to low test rate,IEEE 1149.7 provides a solution of star topology.Based on the standard,QuartusⅡ is used to complete boundary scan test controller that plays an important role in test system.Test principle and process,as well as test controller’s structure and functions are given.Emulation result proves that test controller can generate test signals which can meet the principle requirements.It is available and effective,and it maks a contribution on the test system. |
