Parameter	Description
Saturation Limits	Contains the following options: By width—Allows you to specify the limits in terms of signed or unsigned word size. Bits (1 to 32)—Specifies the word size in bits of the range you want. Unsigned range—Produces nonnegative limits. The minimum and maximum limits are 0 to 2^bits–1, respectively. If the checkbox does not contain a checkmark, the minimum and maximum limits are –2^bits–1 to 2^bits–1–1, respectively. By value—Allows you to specify limits as integers. Upper limit—Specifies the upper limit of the range. Lower limit—Specifies the lower limit of the range.
Input Type	Contains the following options: Signed—Specifies signed integers for the inputs. Unsigned—Specifies unsigned integers for the inputs.

Parameter

Description

Saturation Limits

Contains the following options:

By width—Allows you to specify the limits in terms of signed or unsigned word size.
- Bits (1 to 32)—Specifies the word size in bits of the range you want.
- Unsigned range—Produces nonnegative limits. The minimum and maximum limits are 0 to 2^bits–1, respectively. If the checkbox does not contain a checkmark, the minimum and maximum limits are –2^bits–1 to 2^bits–1–1, respectively.
By value—Allows you to specify limits as integers.
- Upper limit—Specifies the upper limit of the range.
- Lower limit—Specifies the lower limit of the range.

Input Type

Contains the following options:

Signed—Specifies signed integers for the inputs.
Unsigned—Specifies unsigned integers for the inputs.

Block Diagram Inputs

Parameter	Description
upper limit	Specifies the upper saturation limit for input. You configure the default value in the Saturation Limits section of the Configure Saturation dialog box. The value you wire to this input overrides the selection you make in the Configure Saturation dialog box.
input	Any signed or unsigned integer. If input is unsigned, select the Unsigned option in the Configure Saturation dialog box.
lower limit	Specifies the lower saturation limit for input. You configure the default value in the Saturation Limits section of the Configure Saturation dialog box. The value you wire to this input overrides the value in the Configure Saturation dialog box.

Block Diagram Outputs

Parameter	Description
output	The saturated input. input is saturated if input > upper limit or input < lower limit. output = upper limit if input > upper limit output = lower limit if input < lower limit Otherwise output equals input.

Parameter

Description

output

The saturated input. input is saturated if input > upper limit or input < lower limit.

output = upper limit if input > upper limit

output = lower limit if input < lower limit

Otherwise output equals input.
