斯巴达3 XC3s4000 deice上收到错误

嗨，
我在斯巴达3 XC3s4000 deice上收到以下错误。
地点：665  - 该设计有67个块RAM组件，其中11个块RAM组件要求相邻的乘法器站点保持为空。
这是因为相邻块RAM和乘法器站点的某些输入引脚共享路由资源。
此外，该设计有92个乘法器组件。
因此，该设计在设备上总共需要103个乘法器站点。
当前设备只有96个乘法器站点。
我将32位宽度的BRAM替换为两个16位宽度的BRAM，但仍然相同。
可以让我知道它的原因和可用的解决方案。
带着敬意

Hi ,

I am getting the following error on spartan 3 XC3s4000 deice .

Place:665 - The design has 67 block-RAM components of which 11 block-RAM
   components require the adjacent multiplier site  to remain empty. This is
   because certain input pins of adjacent block-RAM and multiplier sites share
   routing ressources. In addition, the design has 92 multiplier components.
   Therefore, the design would require a total of 103 multiplier sites on the
   device. The current device has only 96 multiplier sites.

I replaced the 32 bit width BRAM's to two 16 bit width BRAM's but still getting the same . Can any let me know the reason behing it and the available solution.

With regards
Vintu
