仿真代码设计: 由于SDRAM器件复杂,所以借用了别人已经设计好的SDRAM模型sdram_model_plus.v,并且改动其中内容如下: 激励文件sdram_init_tb.v: `timescale 1ns/1nsmodulesdram_init_tb;regsys_clk;regsys_rst_n;wiresdram_clk;wiresdram_cke;wiresdram_cs_n;wiresdram_ras_n;wiresdram_cas_n;wiresdram_we_n...

SDRAM 这个器件还是比较复杂的,靠我们自己手写仿真非常困难,但我们可以利用 SDRAM 仿真模型 sdram_model_plus.v ,我们再设计一个 testbench,将此仿真模型例化进去即可。 1`timescale 1ns/1ps//时间精度2`define Clock20//时钟周期34moduletop_tb;56//===< 端口 >===7//system ---8regclk ;//时钟,50Mhz...

前面的三篇文章,我们已经简述了基本的SDRAM的基本操作。这里总结一下SDRAM的几个模块,SDRAM的上电初始化,自刷新、读写模块、顶层仲裁控制。了解了上面的操作,我们已经可以完成SDRAM控制器的代码完成,接下来我们便完善SDRAM控制器的接口,简化该SDRAM控制器设计,使得该SDRAM控制器可以很容易的使用。下面的接口定义如下: ...
