Abstract: To improve the efficiency and stability of SoC chip testing board, this paper considers the testing requirement of chip and the modular design and other factors, uses System on Programmable Chip (SOPC) and master computer configuration technology, makes full use of the HSTC expansion interfaces of FPGA development board, designs a batch testing board for multi-chip synchronization testing. It effectively solves the difficult problems in the chip batch testing, and realizes both efficiency and stability. This paper mainly expounds the master computer control method of the testing board, the functional composition of the embedded control system and the design process of the testing program on the chip.
Keywords: SoC; batch testing; FPGA; master computer
