Programmable Drive Strength
The output buffer for each Cyclone II device I/O pin has a programmable
drive strength control for certain I/O standards. The LVTTL, LVCMOS,
SSTL-2 class I and II, SSTL-18 class I and II, HSTL-18 class I and II, and
HSTL-1.5 class I and II standards have several levels of drive strength that
you can control. Using minimum settings provides signal slew rate
control to reduce system noise and signal overshoot.
the possible settings for the I/O standards with drive strength control.
