Table 10-77. Parameter Description
Parameter	Value	Function
WIDTH	1–99 (Limit may vary depending on the family)	Data Width
VOLT (ProASICPLUS Only)	0,1,2,3,4,5	Choice of different voltage levels. 3.3v (PCI), 3.3v and low strength, 2.5v and and high strength, 2.5v and low strength, 2.5v (low power) and high strength or 2.5v (low power) and low strength
SLEW	0,1,2	Choice of different slew rates. Low, Normal or High
TYPE (IGLOO, ProASIC3, SmartFusion, Fusion, Axcelerator and RTAX-S Only)	REG, S_8, S_12, S_16, S_24, F_8, F_12, F_16, F_24, LVCMOS25, LVCMOS18, LVCMOS15, LVCMOS12, PCI, PCIX, GTLP25, GTLP33, HSTL_I, HSTL_II, SSTL3_I, SSTL3_II, SSTL2_I, SSTL2_II, LVDS, LVPECL.	Type of Buffer"S" in S_* denotes Low Slew Rate and "F" in F_* denotes High Slew Rate. Also 8,12,16,24 denote Output drive strengths of 1x, 2x, 3x, 4x respectively.
