Problem Title:
XC5200: New Speed files are now available on the web


Problem Description:
Keywords: XC5200, Speedfiles, Preliminary, Advance

Final -5 and -6 speedfiles as well as preliminary
-3 and -4 speedfiles are available on the web at:

-3/-4 Changes from Advance to Preliminary

XC5200-3/-4 specs and speed files have been extended from the XC5210 only to the
 entire family.  The Advance specs have been updated in the datasheet and are no
w Preliminary.	The new XC5210-4 speed file is approximately 5-10% faster overal
l.



-5/-6 Changes from Preliminary to Final

The Preliminary pin-to-pin specs for -5/-6 have been changed
to the Final specs in the new datasheet.  The most common
path used, using the IOB delay element, has been clarified by
adding a new spec, tPSUL. tPSUL is the path through the CLB
look-up table, while tPSU is the path through the CLB direct
input to the flip-flop.  The setup and hold times for the
path when NODELAY has been chosen on the IOB have  been
increased from the original Preliminary specs.	Note
that these changes have no effect on the speed file, which
did not change in going from Preliminary to Final.
Use the new speed files and data sheet pin-to-pin specs when
analyzing timing for the XC5200 family.
