Problem Title:
XBLOX 5.x: internal error 20224, existence_error


Problem Description:
When running XBLOX on a workstation during a functional simulation flow, you
may see:

   *** 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.
   existence_error(format('$stream'(5963780),'.'(80,'.'(73,'.'(78,'.'(44,'
   .'(32,'.'(126,'.'(97,'.'(44,'.'(32,'.'(126,'.'(97,'.'(44,'.'(32,'.'(126
   ,'.'(97,'.'(44,[])))))))))))))))),'.'('D_IN','.'('I','.'('PCQDI',[]))))
   ,1,stream,'$stream'(5963780),0)

The only known cause of this problem is that XBLOX has run out of swap
space.	(Ignore the line at the bottom of the output when XBLOX says that it
used only xxx.xxxK of memory; this is completely incorrect.  Use ps to find
the actual memory used.  XBLOX is doing a fork at this point, so the amount
of memory used at the instant of the failure is approximately double that
specified by the ps command).


Solution 1:

Increase your workstation's swap space, or run the design flow on a machine
with more swap space.
