SLEW_RATE

Implements control of low-to-high/high-to-low transitions on output pins to help reduce switching noise. When a large number of output pins switch simultaneously, pins that use the lower Slew Rate option help reduce switching noise. This option is ignored if it is applied to anything other than an output or bidirectional pin, or a top-level design entity containing output or bidirectional pins. Note that using this option may increase the delay for output or bidir pins, which can affect slack on Tco paths for the pins this is applied to.
