基于FPGA的多用信号源的设计与实现

Design and Implementation of Multiple Signal Source Based on FPGA

鉴于传统多用信号源设计实现的外围电路过于复杂,应用EDA技术,以FPGA器件为棱心,用VHDL语言设计各功能模块,最后以原理图编辑方式完成顶层文件的信号源设计．信号源的实现表明,采用FPGA设计的信号源不仅可很容易地满足设计要求,而且外围电路简单．

To avoid the complexity in the traditional design, using the technique of EDA, taking FPGA as the kernel and employing language of VHDL to design the functional modules, the design of the exterior documents of the signal source can be accomplished by edit method of principle chart. The implementation of the signal source shows that the signal source based on FPGA can not only achieve complex frequency modulation and amplitude modulation conveniently, but have a simple peripheral circuit.
