基于FPGA LPM多功能信号发生器设计

摘要

With the FPGA chip for the carrier,through the QuartusⅡ LPM_ROM module and VHDL language as the core,a multi-functional signal generator is designed.According to the input signal choice,five kinds of signal can be output,including increase sawtooth wave,decreasing sawtooth wave,triangle wave,ladder wave and square wave.Through wave form simulation and timing analysis with the QuartusⅡ software.After the simulation is correct,the resources provided by experimental board is download to chip for achieving the function.%以FPGA芯片为载体,通过QuartusⅡ的LPM_ROM模块和VHDL语言为核心设计一个多功能信号发生器,根据输入信号的选择可以输出递增锯齿波、递减锯齿波、三角波、阶梯波和方波等5种信号,通过QuartusⅡ软件进行波形仿真、定时分析,仿真正确后,利用实验板提供的资源,下载到芯片中实现预定功能。
