基于FPGA的软硬件协同测试的设计与实现

硬件开发过程中，测试往往是影响产品的重要环节。纯硬件的测试往往受到设备及环境的影响，而如果完全用软件仿真，则速度太慢，影响开发进度。针对这种情况，作者提出一种软硬件协同测试的方法，利用FPGA实现PC机与待测设备的互连，不但尧分利用了PC机的丰富资源，同时发挥出硬件工作速度快的特点。该系统采用FPGA完成控制功能，实现高速、实时的双向数据通道，同时，利用FPGA灵活设计待测设备的接口，使该系统可广泛应用于各种设备的测试与分析。

Design for HW/SW Co-Testing Based on FPGA

Testing is a key link of hardware design.Hardware testing is affected by equipments and environment,while simulation by software will cost too much time.In view of this situation,a methodology of HW/SW co-testing is proposed,which takes full advantage of PC's resources and hardware's speed.(FPGA) is utilized to accomplish the controlling function and to establish a high-speed real-time bidirectional data path.The interface to the device under test is flexibly designed by FPGA,thus the system can be widely used in the measurement and analysis of various devices.
