This section discusses slew-rate control and MultiVolt I/O interface
operation for FLEX 8000 devices.
Slew-Rate Control
The output buffer in each IOE has an adjustable output slew rate that can
be configured for low-noise or high-speed performance. A slow slew rate
reduces system noise by slowing signal transitions, adding a maximum
delay of 3.5 ns. The slow slew-rate setting affects only the falling edge of
a signal. The fast slew rate should be used for speed-critical outputs in
systems that are adequately protected against noise. Designers can specify
the slew rate on a pin-by-pin basis during design entry or assign a default
slew rate to all pins on a global basis.
