基于Testbench的FPGA实物自动化测试环境设计

摘要

针对FPGA软件测试过程中仿真测试和实物测试的不足,提出了一种基于仿真测试用例的实物自动化测试环境,将用于仿真测试的Testbench进行解析处理,形成能够用于FPGA实物测试的传输信号,通过执行器将此信号转换为作用于被测FPGA芯片的实际信号,并采集被测FPGA芯片的响应,实现对FPGA的实物自动化测试.采用实物自动化测试环境验证平台对设计架构进行了验证,取得了良好的效果.%According to the shortcomings of simulation testing and physical testing method of FPGA software testing,a design of FPGA physical automatic testing environment based on simulation testing case was proposed.The Testbench used in simulation testing was parsed and processed into FPGA transmission signals used in physical testing.An actuator was designed to convert the testing data into real signals transmitted between FPGA under test and the testing environment.The design framework was validated by a physical automatic testing environment verification platform,and good results had been achieved.
