Sould IBIS reflect SPEC or actual silicon?

Hello IBIS folk:

   I've got a question regarding what IBIS file should reflect:
The actual silicon parameters or spec parameters?

  This might seem an odd question but - lets consider the
following case as an example: Let say that some signal is able
to drive currents up to 10mA (this is its electrical characteristic).
Now because of elecromigration limmitations the alowable current
in the spec is only 5mA. In this case, what should the IBIS file
reflect - the 10mA (the actual silicon characteristic) or thr 5mA
(the SPEC limmitation)?

  Thanks in advace.
