大家帮我翻译一下这些内容，谢谢，毕业论文急用，，，，，，。。。

引进的EDA technolgies ， VHDL语言，以及芯片adc0809的原则，以及如何使用VHDL硬件描述语言设计adc0809采样控制电路，而采样是由于控制电路在quartus ⅱ 7.2软件环境的模拟波函数，并通过FPGA在实现A / D采样控制器。实践证明，电路设计，可以稳定，可靠的工作

Introducing the EDA technolgies, VHDL language, and the chip ADC0809 principle and how to use VHDL hardware description language design ADC0809 sampling control circuit, while sampling is given control circuit in Quartus Ⅱ 7.2 software environment simulation of the wave function, and through the FPGA to achieve A / D sampling controller. Practice has proved that the design of the circuit can be stable, reliable work
