Check optimization settings

Condition

Recommended Action

The specified optimizations are off.

Select the following optimization check boxes on the

Optimization pane in the Configuration Parameters

dialog box:

• “Block reduction”

• “Conditional input branch execution”

• “Implement logic signals as Boolean data (vs.

double)”

• “Remove root level I/O zero initialization”

• “Remove internal data zero initialization”

• “Use memset to initialize floats and doubles to

0.0”

• “Remove code from floating-point to integer

conversions that wraps out-of-range values”
