VHDL参考例程--日如DAC0832接口电路程序-VHDL reference routines- on procedures such as the DAC0832 Interface Circuit

fpga核心源码，有利于学习，适合初学者学习-fpga core source code, there is conducive to learning, suitable for beginners to learn

说明：  QSPI_FLASH_MODEL 可以设计时前端仿真使用(QSPI?_Flash_Model can be used in front-end simulation at design time)

说明：  XC7A35TCSG324-1的Verilog频率计程序，支持十分频，支持切换内外信号输入(Verilog frequency meter program of xc7a35tcsg324-1 supports decadal frequency division and switching internal and external signal input)

SPI接口的vhdl代码，可以实现与单片机的spi通信，完整的工程-SPI interface of the VHDL code can be achieved with SCM spi communication, complete works

VHDL 源码模块，可以实现最经典原PWM，可以用于电源，电机的控制()

中频70M，30M带宽LFM信号，采样率为102.4M，，数字下变频后，还进行了三倍抽取，最后还得到I，Q两路信号 (IF 70M, 30M bandwidth LFM signal, the sampling rate 102.4M, under digital variable frequency after also carried out three times extracted, and finally also received the I and Q signals)

IEEE Standard for Verilog 2005

This is verilog source code for DES(Data Encryption standard) which is used in network security.
