Abstract
IEEE 1500 Standard defines the behavior of test wrapper and core test language
which enables test reuse for embedded IP cores.Based on the research of IEEE 1500 Standard
the IP core test wrapper of an ISCAS89 Benchmark S349 circuit is designed and verified.The simulation results are presented showing the efficiency of the test wrapper under all instructions.Wrapper Creator tool is implemented and applied to several benchmarks
through simulation the correctness of tool is verified.
