Validation model

Enable or disable generation of a validation model

Model Configuration Pane: Global Settings / Model Generation

Description

Enable or disable generation of a validation model that verifies the functional equivalence of the original model with the generated model. The validation model contains the original and the generated DUT models. You can use the generated DUT model to observe the effect of block settings and optimizations such as resource sharing, streaming, and delay balancing.

If you enable generation of a validation model, make sure that delay balancing is enabled on the model (its default). Delay balancing keeps the generated DUT model synchronized with the original DUT model. Validation fails when there is a mismatch between delays in the original DUT model and delays in the generated DUT model. See Resolve Numeric Mismatch with Delay Balancing.

Settings

off (default) | on

Default: Off

on

Select this setting to generate the validation model. By default, HDL Coder™ generates code and the validation model. To generate only the validation model, clear the Generate HDL code check box.

off

Clear this setting when you do not want to generate the validation model. When you click the Generate button, HDL Coder generates code for the model.

Tips

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

By default, the GenerateHDLCode property is enabled. You can use this property in conjunction with the GenerateValidationModel property to specify whether to generate the validation model and the HDL code. To generate the code and the validation model, enable the GenerateValidationModel property with makehdl.

hdlset_param('sfir_fixed', 'GenerateValidationModel','on');
makehdl('sfir_fixed/symmetric_fir')

If you want to generate only the validation model, disable the GenerateHDLCode property and enable the GenerateValidationModel property with makehdl.

hdlset_param('sfir_fixed', 'GenerateValidationModel','on');
hdlset_param('sfir_fixed', 'GenerateHDLCode',off');
makehdl('sfir_fixed/symmetric_fir'
