Remove Unused Ports - Remove unused ports from the design - MATLAB (original) (raw)

Main Content

Remove unused ports from the design

Since R2020b

Model Configuration Pane: Optimization / General

Description

The Remove Unused Ports parameter removes ports from your design that are unused from the generated HDL code.

Settings

On (default) | Off

On

Removes ports in your design that are unused from the generated HDL code. This optimization preserves unused ports at the top-level DUT subsystem. All other unused ports are removed from the HDL code.

Off

Do not remove unused ports from the HDL code.

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