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
XC3S4000 is pin compatible with XC3S2000 but uses alternate differential pair labeling on six package balls (H20, H21, H22, H23, H24, J21).
XC3S5000 is pin compatible with XC3S4000 but uses alternate differential pair functionality on fifteen package balls (A3, A8, B8, B18, C4, C8, C18,
D8, D18, E8, E18, H23, H24, AB9, and AC9).
