输入到输出互连和输出到输入互连

我试图把一个输出列勾回到芯片的输入端，这样我就可以在不同的行中使用这个信号。我需要通过行来输出互连，以在行上执行块或块之间的异或。这阻止了我使用行的广播特性。我知道无论我选择输入输出互连或反之亦然的图标是一样的：输入输出。我在哪里可以找到关于这个资源的信息？或者有人能解释一下？

  I'm trying to hook an output column back to the input side of the chip so I can use the signal in a different row.  I need to go through the Row to output interconnect to perform an exclusive or between to blocks on the row.  This prevents me from using the broadcast feature of the row. I notice that whether I select input to output interconnect or vise versa the icon remains the same: input to output.  Where do I find information about this resource? Or can someone explain?
