Check Relational Operator blocks which use floating point types have boolean outputs.

Available with Simulink^® and HDL Coder™.

Description

This check displays a warning if your Simulink model contains Relational Operator blocks that compare floating-point data types and produce a nonboolean output. By default, the Output data type of the block is boolean. If you specify a nonboolean output, the block implementation after HDL code generation is not optimal, and can increase the resource usage on the target hardware device.

Results and Recommended Actions

To fix this warning, click Modify Settings and the code generator changes the Output data type of the block to boolean.
