说明：  这两个examples 的源码是modelsim 自带教程里面最重要的两个！但是其中一个（memory）在大多是安装文件目录下没有，但是又很有用，我找了好久才找到,PDF上说这几个文件在：<modelsim安装目录>\examples\memory\verilog下:dp_syn_ram.v,ram_tb.v,sp_syn_ram.v 但是找过的人都知道，一般的版本下面都没有这个源码。我分享一下，方便大家查找！
(These two examples of the source is modelsim tutorial which comes with the two most important! But one of the (memory) is installed in most of the files directory does not, however, and very useful, I found a long time to find, PDF files, said these: <modelsim安装目录> \ Examples \ memory \ verilog under: dp_syn_ram.v, ram_tb.v, sp_syn_ram.v but had to find people know, the general version of the following do not have the source code.
