Problem Title:
XBLOX 5.x: Internal error 20224: representation_error


Problem Description:
XBLOX: ERROR 20224:
   INTERNAL ERROR
   Please contact Xilinx Technical Support.  Please provide the following
   details to the support personnel.  This information will be needed by
   the software developers.

   1. representation_error(is(_10269,+(abs(-(-2147483647,2147483647)),1)),
      2,'integer overflow')

This error message usually occurs if you are using a SLICE component with a
SUB bus width of 1 (single bit).  Apparently, XBLOX cannot properly handle
a SLICE of this type.


Solution 1:

Replace the SLICE with an ELEMENT, which can be thought of as a special
class of the SLICE component.
