嗨，
请通过UG388获取支持的内存设备列表。
我认为Nanya不是赛灵思的硬件评估，所以我们不能保证它的工作原理。
但你没有提到什么不起作用。
由于你不能为Nanya部分生成MIG，你可以使用自定义部件，请检查所有的时序参数是否按照nanya数据表正确设置。
通过UG的调试部分，确定哪个校准阶段失败以及是否有任何数据错误
确保您的时钟和复位电路正确并且符合电路板布局指南
在主AR下面，按照概述的步骤操作。

希望这可以帮助
问候，

Hi,
 
Please go through UG388 for list of Supported memory devices.
I think Nanya is not hardware evaluated by Xilinx so we cannot assure that it works.
But you have not mentioned what is not working.
As you cannot genearte MIG for Nanya part you would have use custom part, please check if all the timing parameters were properly set as per nanya datasheet.
Go through Debugging section of UG and figure which stage of calibration is failing and if any data errors
 
Make sure your clocking and reset circuitry is proper and board layout guideliness were met
 Go through below master AR and follow the steps outlined.

Hope this helps

想想，我听从了你的帮助。
现在MIG正在工作。
现在我的控制器MIG
输入I有8位数据和7位addr。
内存返回总是FF不明白
我的代码是吼叫

Thinks, I followed your help. now MIG are working.
 
Now my controller MIG 
Input I have 8 bits data and 7 bits addr. 
The memory returns always FF don’t understand
 
My code is bellow

你的意思是说默认MIG正在工作，但你看到自己的流量出现数据错误？
如果是，请按照命令，在UG388中写入和读取时序图，并对信号进行交叉检查。
如果这是在HW，我建议您在模拟中验证。

以下为原文

You mean to say default MIG is working but you see data errors with your own traffic?
If yes please follow the command, write and read  timing diagrams in UG388 and cross check against your signals.
If this is in HW I would sugget you to verify in simulation.
