是否可以使用两个不同的MCB将两个不同的So-DiMM DDR2存储器连接到电路板上？

如果可以使用两个不同的MCB将两个不同的So-DiMM DDR2存储器连接到我们的电路板上？
Spartan 6 MCB不支持此功能。
每个MCB支持单个DRAM设备，并且不支持多设备SO-DIMM。
也不支持使用多个Spartan 6 MCB来支持单个多设备SO-DIMM。
你的选择是
设计自己的（非MCB）内存控制器
使用Virtex 5或Virtex 6代替Spartan 6. Virtex 5/6系列支持SO-DIMM应用
使用MIG生成Spartan-3软内存控制器，并在其上“破解”以将代码移植到Spartan 6目标

if it is possible to connect two different So-DiMM DDR2 memories to our board using two different MCBs?

This is not supported with the Spartan 6 MCBs.  Each MCB supports a single DRAM device, and there is no support for multi-device SO-DIMMs.  Nor is there support for using multiple Spartan 6 MCBs to support a single multi-device SO-DIMM.
 
Your options are to

• design your own (non-MCB) memory controller
  
• use Virtex 5 or Virtex 6 instead of Spartan 6.  Virtex 5/6 families support SO-DIMM applications
  
• using MIG to generate a Spartan-3 soft memory controller, and 'hack' on it to port the code to a Spartan 6 target
  

You really should be reading the MIG user guides, and memory user guides, which are readily available on the Xilinx website.  A simple search will point you to these documents in very short order.  All of the questions you ask are answered in these documents.

How many pins of my FPGA device will be used for connecting both memories using So-DiMMs? I hope not all 2x200 :-)How many pins of my FPGA device will be used for connecting both memories using So-DiMMs? I hope not all 2x200 :-)

This question would suggest either profound ignorance or profound lack of effort on your port.  In either case, this is the sort of request that scares people (me, particularly) away from helping you.  You should spend some time understanding DRAM devices and operating fundamentals before embarking on an ambitious design project.

只是快速评论eteam00的其他非常好的帖子：
“使用MIG生成一个Spartan-3软内存控制器，然后'hack'将代码移植到Spartan 6目标”
这将比它的价值更麻烦。
Spartan-3系列设计依赖于Spartan-6中不存在的本地时钟路由。
虽然有可能复制类似S3设计的东西，但更好的方法是在这里使用S6软件：http：//www.xilinx.com/products/ipcenter/PHYDDR2-SDRAM.htm。
然后你可以添加自己的控制器。
该phy专为更广泛的接口而设计。



以下为原文

Just a quick comment on eteam00's otherwise very fine post:
 
 "using MIG to generate a Spartan-3 soft memory controller, and 'hack' on it to port the code to a Spartan 6 target"
 
That will be more trouble than it is worth.  The Spartan-3 family designs rely on local clock routing that doesn't exist in Spartan-6.  While it might be possible to replicate something like the S3 design, a better approach would be to use the S6 soft phy here: http://www.xilinx.com/products/ipcenter/PHYDDR2-SDRAM.htm.  Then you can add your own controller.  This phy is designed for wider interfaces.

“使用MIG生成一个Spartan-3软内存控制器，然后'hack'将代码移植到Spartan 6目标”
这将比它的价值更麻烦。
是的，除了那些有更多时间而不是金钱的人:)
Spartan-3家族
设计依赖于Spartan-6中不存在的本地时钟路由。
为了增加其他注意事项，虽然时钟速率限制（即性能降低）可能完全可以接受，但过多的时钟偏差（在DDR接口和内部软核中）在任何时钟频率都是致命的。

更好的方法是在这里使用S6 soft phy：http：//www.xilinx.com/products/ipcenter/PHYDDR2-SDRAM.htm。

您仍然需要为此PHY IP添加控制器设计。
我不知道这个IP的成本，但它不是免费的。
这个PHY IP是免费的！
凉！
如果控制器IP成本足够，那么最好不要驱动Virtex 5/6器件，MIG完全支持DRAM模块应用（包括控制器）。

"using MIG to generate a Spartan-3 soft memory controller, and 'hack' on it to port the code to a Spartan 6 target"

Yes, except for those folks who have more time than money :)

The Spartan-3 family designs rely on local clock routing that doesn't exist in Spartan-6.

To add to other caveats, while clock rate limitations (i.e. reduced performance) may be perfectly acceptable to some, excessive clock skew (in both DDR interface as well as internal soft core) is fatal at any clock frequency.

While it might be possible to replicate something like the S3 design, a better approach would be to use the S6 soft phy here: http://www.xilinx.com/products/ipcenter/PHYDDR2-SDRAM.htm.  Then you can add your own controller.  This phy is designed for wider interfaces.

• You still need to add a controller design to this PHY IP.
  
• I do not know the cost of this IP, but it isn't free.  This PHY IP is free!  Cool!
  
• If the controller IP costs enough money, you may be better off driving a Virtex 5/6 device, which is fully supported by MIG for DRAM module applications (and includes the controller).

这个软phy是免费的：http：//www.xilinx.com/products/ipcenter/PHYDDR2-SDRAM.htm。
（除非我不看的时候发生了变化！）
你是对的，不包括控制器。
如果您愿意，可以从Northwest Logic购买配套控制器。
如上所述，根据您的需求，时间表和预算，有许多权衡因素，V5或V6甚至7系列可能是更好的解决方案。



以下为原文

This soft phy is free:  http://www.xilinx.com/products/ipcenter/PHYDDR2-SDRAM.htm. (unless something changed when I wasn't looking!)
 
You are correct that the controller is not included.  You can buy the companion controller from Northwest Logic if you wish.
 
As noted, there are many tradeoffs and a V5 or V6 or even 7 Series may be a better solution depending on your needs and timeframe and budget.

谢谢你的纠正。
我认为NW Logic核心的成本为$$。
我已经编辑（并更正了）我以前的帖子。

There would be no point in answering such a question until you showed some sign of having read an SO-DIMM datasheet.
