IP cores without I/O multiplexing are typically unavoidable to be embedded into SoC due to the necessary considerations such as pin constraint and performance optimization during the design stage.Hence

one of the serious challenges for SoC testing is how to effectively test IP cores without I/O multiplexing because the ports of IP cores without I/O multiplexing cannot be directly connected to the ATE channels.In this paper

we propose test methods for ADC and DAC IP cores without I/O multiplexing using V93000 ATE respectively.In order to test the ADC and DAC IP cores without I/O multiplexing

test programs are firstly developed and loaded into V93000 to configure the two cores via EMIF bus.Then the digital codes and the analog voltage values respectively converted by ADC and DAC IP cores of SoC are captured by V93000 for performance parameter calculation.Experimental results show that the proposed methods are effective.
