Re: [foxboro] Reduce IFL's for FBM

Before you folks get too carried away, I don't think that you get more IFLs
or OFLs by splitting up the PLB into multiple blocks.  These resources are
maintained in the FBM itself, with supporting logic in the PLB blocks.  In
fact, when using multiple PLB blocks you need to be very careful about
overlapping resources.  If resources ARE overlapped, the last processed
block "wins" and overwrites any previous logic.

That's interesting, I've never tried it either, the number of cout's is 
still restricted to the FBM, but more ifl's offer more possible interlocks.
