摘要
采用DDS技术设计工业控制现场测试信号源,基于VHDL语言进行系统建模,对DDS进行重新参数设计,实现IP核重构,能够根据需要修改参数以实现器件的通用性;利用QuartusⅡ平台完成具体DDS芯片设计,阐述了基于VHDL编程的DDS设计的方法步骤。经测试,该设计各项设计指标符合要求,具有很好的实用价值。
The DDS technology is used to design industrial control field test signal source. The system is imitated based on VHDL language. Parameter is redesigned for the DDS and the kernel of IP is reconstructed. In the light of demand to revise the parameter, which is achieved the commonality of device. Using the platform of Quartus Ⅱ to complete the definite design of DDS chip. The methods and steps of DDS＇ s design based on VHDL program are expounded. The design specifications conformed to demand by test. It has a very good practical value.
