The Saturate block limits output to a maximum value. If the output is greater than
the maximum positive or negative value to be represented, the output is forced (or
saturated) to the maximum positive or negative value, respectively. Alternatively, you
can truncate the MSB.

Value
shows the Saturate block parameters.
Specifies the number of bits to the right of the binary point. This
Specifies how many bits to remove.
Turn on if you want to pipeline the function.
Turn on to use the saturation occurred input (sat_flag).
Turn on to use the clock enable input (ena).
Turn on to use the asynchronous clear input (aclr).
The number format of the bus.
Specifies the number of bits to the left of the binary point, including the
sign bit. This parameter does not apply to single-bit buses.
parameter applies only to signed fractional buses.
Saturate, truncate, or specify the saturation limits for the output.
Specifies the upper saturation limit when Saturation Type is set to Enter
Saturation Limits.
Specifies the lower saturation limit when Saturation Type is set to Enter
Saturation Limits.
