Transform non zero initial value delay

This parameter is in the HDL Code Generation > Optimization > General tab of the Configuration Parameters dialog box. Enable this option to optimize Delay blocks with non zero initial condition.

Settings

Default: On

On

Transform Delay blocks with nonzero Initial condition in your Simulink^® model to Delay blocks with zero Initial condition and some additional logic in the generated HDL code.

By using this transformation, HDL Coder™ can perform optimizations such as sharing, distributed pipelining, and clock-rate pipelining more effectively, and prevent an assertion from being triggered in the validation model.

Off

Do not transform Delay blocks with nonzero Initial condition in your Simulink model.

Command-Line Information

Property: TransformNonZeroInitValDelay

Type: character vector

Value: 'on' | 'off'

Default: 'off'

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

For example, you can set the TransformNonZeroInitValDelay property to on 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', ... 
        'TransformNonZeroInitValDelay','on')

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