Share floating-point IPs in the design

Model Configuration Pane: Optimization / Resource sharing

Description

The Floating-point Ips parameter enable the use of resource sharing optimization to share floating-point IPs in your design.

Dependencies

To share floating-point IPs:

• In the HDL Block Properties for the parent DUT Subsystem, specify the SharingFactor. The number of floating-point IP blocks that get shared depends on the SharingFactor that you specify for the subsystem.
• In the Configuration Parameters dialog box, in the > pane, select Use Floating Point.

Settings

On (default) | Off

On

When you enable resource sharing, HDL Coder™ shares floating-point IP blocks.

Off

Do not share floating-point IP blocks.

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 use the ShareFloatingPointIPs setting when you generate HDL code for the symmetric_fir subsystem inside the sfir_fixed model using either of these methods.

• Pass the property as an argument to themakehdl function.
  makehdl('sfir_fixed/symmetric_fir', ...
  'ShareFloatingPointIPs','on')
• When you use hdlset_param, you can set the parameter on the model and then generate HDL code usingmakehdl.
  hdlset_param('sfir_fixed','ShareFloatingPointIPs','on')
  makehdl('sfir_fixed/symmetric_fir')
