摘要
使用了基于FPGA的Xilinx公司Spartan-3E系列的XC3S250ETQG144处理器,对A/D转换芯片TLC549进行驱动采样和后续实际电压值读取.采用Verilog语言,整个模块设计在ISE的环境下进行,设计时减少复杂逻辑,精简模块设计,实现高速A/D转换和时序控制,该设计可移植性强,利用ISE进行编译、综合、仿真,为后续A/D转换的工作提供了实验依据.实验表明设计可靠性高,可以满足A/D转换的高精度、实时性、抗干扰等方面的要求.
It uses the Xilinx Company Spartan-3E series of XC3S250ETQG144 processor based on FPGA to A/D conversion chip TLC549 driven sampling and later actual voltage value of reading. By use of Verilog language, the whole module design is under the environment of ISE with less complex logic, compact modular design,high speed A/D conversion and sequential control. The portability is strong. And then, we use ISE compile, synthesize and simulation,for the follow-up A/D conversion work provises experimental basis. Experimental results show that the design reliability is high, which can satisfy the A/D conversion of high precision, real-time, anti-jamming requirements.
