Design of SOC test scheduling controller

In the SOC(system on chip) test,TAM(test access mechanism)and test controller are the important parts of SOC test architecture.A novel SOC test scheduling controller based on test buses was designed.IP cores that controlled by commands of test controller could flexibly work in different test modes.Test controller could configure test buses to achieve parallel test for IP cores of SOC and reduce test time.Experimental results show that the design is reasonable and efficient on completing test task.
