With pre-emphasis, the output current is boosted momentarily during switching to
increase the output slew rate. The overshoot introduced by the extra current happens
only during switching and does not ring, unlike the overshoot caused by signal
reflection. The amount of pre-emphasis needed depends on the attenuation of the
high-frequency component along the transmission line. The Quartus II software
allows two settings for programmable pre-emphasis—disabled (0) and enabled (1).
The default setting is enabled.
