AD9910实现脉冲内线性调频信号，仅供参考(AD9910 to achieve linear FM pulse signal, for reference only)

2004 SNUG of systemverilog

说明：  verilog编码器、计数器、加法器的程序(Verilog encoder, counter, adder procedures)

本实例用于SDRAM完成读写功能: 先向SDRAM里面写数据，然后再将数据读出来做比较，如果不匹配就通过LED变亮显示出来，如果一致，LED就不亮。(The examples for SDRAM read and write functions.)

说明：  NAND FLASH的多个仿真模型，可以用于接口设计的测试(NAND FLASH multiple simulation model that can be used for the test interface design)
