Use Floating Point

Specify use of native floating-point library

Since R2023a

Model Configuration Pane: Floating Point

Description

Use the native floating-point library in your design. You can specify the latency strategy and whether to handle denormal numbers in your design. See Latency Strategy and Handle Denormals.

Settings

off (default) | on

Default: Off

on

Map your design to the native floating-point target library.

off

Do not map your design to the native floating-point target library.

Tips

To set this property, use the functions hdlset_param or makehdl. To view the property value, use the function hdlget_param.

For example, you can enable the UseFloatingPoint setting when you generate HDL code for the symmetric_fir subsystem inside the sfir_single model by using either of these methods:

• Pass the property as an argument to the makehdl function.

  makehdl('sfir_single/symmetric_fir', ... 
          'UseFloatingPoint','on')

• When you use hdlset_param, set the parameter on the model and then generate HDL code by using makehdl.

  hdlset_param('sfir_single','UseFloatingPoint','on')
  makehdl('sfir_single/symmetric_fir')

Recommended Settings
