Design of high-speed Boundary-scan master controller base on SOPC

According to the IEEE Std 1149.1, a kind of high speed Boundary-scan master controller is designed base on SOPC. Through the master controller's configuration, users can get the control signals which are used to test the output, and the frequency of the test clock can be as high as 50MHZ, the efficiency of Boundary-scan test improve greatly. Meanwhile, as a practical value component, the master controller IP core can be used to SOPC's test without special boundary scan test equipment. The timing simulation waveforms and digital oscilloscope observation prove that the test signals generated by Boundary-scan master controller meet the test requirements, and the design is reasonable.
