Floating-Point IPs

Share floating-point IPs in the design

Model Configuration Pane: Optimization / Resource sharing


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


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 HDL Code Generation > Floating Point Target pane, select Use Floating Point.


On (default) | Off

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


Do not share floating-point IP blocks.


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 ShareFloatingPointIP 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 the makehdl function.

    makehdl('sfir_fixed/symmetric_fir', ... 
  • When you use hdlset_param, you can set the parameter on the model and then generate HDL code using makehdl.
