tributed between the eight I/O banks for the XC3S1000 in
the FG676 package. Similarly,
available user-I/O pins are distributed between the eight I/O
banks for the XC3S1500 in the FG676 package. Finally,

XC3S1500 balls D25 and F25 are not VREF pins although they are
designated as such. If a design uses an IOSTANDARD requiring
VREF in bank 2 then apply the workaround in
20519
XC3S4000 is pin compatible but uses alternate differential pairs on
six package balls.
