The design and implementation of extensible SOPC system board

With the rapid development of EDA technology, many universities have set up the digital design course in the computer science speciality. The digital design course needs SOPC system board to mount FPGA and the appropriate support circuitry. This paper presented the design of extensible SOPC system board. This board has compact structure and embodies the characteristics of SOPC system such as high integration and strong flexibility. The cheaper chip with a unique combination of high functionality, low power and low cost is selected and used in the design to reduce the cost. The high-speed mezzanine interface is used in the design to expand the functionality of the development board through the addition of daughter cards. The functional test and application verification is carried out for the system board and the results are in accordance with the design requirements.
