VCS中仿真带RAM IP的设计时出现的问题

xm900626

本人在编写一个testbench时，遇到了一个问题，DUT中的RAM例化自ISE的IP，编译时在命令行加入了如下选项指向ISE提供的Lib

1. COMP_OPTS += -y /home/project_xu/ISE_lib/src/unisims
   
2. COMP_OPTS += -y /home/project_xu/ISE_lib/src/XilinxCoreLib
   
3. COMP_OPTS += -y /home/project_xu/ISE_lib/src/unimacro
   
4. COMP_OPTS += -y /home/project_xu/ISE_lib/src/simprims
   
5. COMP_OPTS += -y /home/project_xu/ISE_lib/src/uni9000
   
6. COMP_OPTS += +incdir+/home/project_xu/ISE_lib/src
   
7. COMP_OPTS += +libext+.v
   

复制代码

结果编译通过，但是在运行仿真时，终端始终显示如下，没有往下执行testbench，也没有报错：

然后尝试了带乘法器IP的DUT，仿真没有问题，在网上看到有人说ISE自带的IP生成的Block Ram是不能被VCS编译的，请问各位这可能是哪里出问题了？急~~~~~急~~~~~急~~~~~

可木

LZ这个问题解决了么？我也碰到了。。。

楼主这个问题解决了吗？我也遇到类似的问题了，但是我是在compile的时候就出现这个问题，同时伴随一堆的blk_mem_gen_v7_3 WARNING: Address 1f is outside range for A Read
