Vivado：由IBUF推动的IBUFDS_GTE2？

嗨，Pat，当您在ooc模块上运行实现时出现错误，您需要在ooc模块内实例化缓冲区。顶级综合通常会推断所有顶级端口上的IO缓冲区。
但是，如果在OOC模块中专门实例化IO缓冲区，则必须逐个端口地关闭顶层综合中的IO缓冲区插入。
对于Vivado综合，执行此操作的属性是BUFFER_TYPE。
有关BUFFER_TYPE qplease的更多信息，请参阅Vivado Design Suite用户指南：综合（UG901）。谢谢，Deepika。

Hi Pat,

As the error comes up when you run implementation on ooc module, you need to instantiate buffers inside the ooc module.

The top level synthesis will typically infer IO buffers on all top level ports. However, if IO buffers are specifically instantiated in an OOC module, you must turn off IO buffer insertion in the top-level synthesis on a port-by-port basis.

For Vivado synthesis, the attribute to do this is BUFFER_TYPE. For more information on BUFFER_TYPE qplease refer to the Vivado Design Suite User Guide: Synthesis (UG901).

Thanks,
Deepika.Thanks,

嗨Pat，
原始IBUFDS_GTE2原语需要在I和IB引脚上插入IBUF才能正确放置。
在您的情况下，因为您已将模块设置为OOC，所以合成将不会在模块端口上插入IBUF，从而导致错误。
您需要在HDL中实例化IBUF，使其看起来如下所示。
谢谢，
迪皮卡。

Hi Pat,
 
The primitive IBUFDS_GTE2 primitive needs IBUF inserted on the I and IB pins for it to be properly placed. 
 
In your case as you have set the module as OOC the synthesis will not insert IBUF on the module ports and hence the error.
 
You need to instantiate IBUF in th HDL so that it looks like below.
 

 
Thanks,
Deepika.
