摘要
为了降低空间科学实验电子设备的功耗,通过对不同的FPGA进行比较,选用Actel公司的低功耗FPGA器件M1AGL600V2设计并实现应用于空间科学实验的SPI数字复接器;使用VerilogHDL语言采用自顶向下的设计方法编写源程序,结合Actel公司提供的IP核实现了数字复接功能;利用Libero软件工具的功耗管理功能进一步降低系统的功耗,最终系统实际测量功耗小于15 mW,适用于空间科学实验等对功耗有严格限制的环境。
In order to reduce the space science experiment electronic devices＇ power consumption,Actel＇ low power FPGA device M1AGL600V2 is chosen after comparison of different FPGAs to achieve low power SPI digital signal multiplexer,which would be used in space science experiments.This article introduces the design of multiplexer with VerilogHDL program in detail,and presents the combination of user program and IP cores.The power management tools of the design software Libero are used to reduce power consumption to 15 mW,which makes the multiplexer perfect in environments with strict power restraint.
