PostTargetReferenceDesignFcn

Syntax

Description

PostTargetReferenceDesignFcn registers a function handle for the callback function that gets called at the end of the Set Target Reference Design task in the HDL Workflow Advisor. If hRD is the reference design object that you construct with the hdlcoder.ReferenceDesign class, use this syntax to register the function handle:

hRD.PostTargetReferenceDesignFcn = @my_reference_design.callback_PostTargetReferenceDesign

To define your callback function, create a file that defines a MATLAB^® function and add it to your MATLAB path. You can use any name for the callback function. In this example, the function name is callback_PostTargetReferenceDesign, and is located in the reference design package folder +my_reference_design.

With the callback function, you can enable custom validations for your design. This example code shows how to create the callback function and validate that the reset type is synchronous.

function callback_PostTargetReferenceDesign(infoStruct)
% Reference design callback run at the end of the task Set Target Reference Design
%
% infoStruct: information in structure format
% infoStruct.ReferenceDesignObject: current reference design registration object
% infoStruct.BoardObject: current board registration object
% infoStruct.ParameterStruct: custom parameters of the current reference design, in struct format
% infoStruct.HDLModelDutPath: the block path to the HDL DUT subsystem
mdlName = bdroot(infoStruct.HDLModelDutPath);
hRD = infoStruct.ReferenceDesignObject;
refDesignName = hRD.ReferenceDesignName;

isResetSync = strcmpi(hdlget_param(mdlName, 'ResetType'), 'Synchronous');

% Reset must be synchronous
if ~isResetSync
    error('Invalid Reset type. Reset type must be synchronous');
end
end

In the HDL Workflow Advisor, when HDL Coder™ runs the Set Target Reference Design task, it executes the callback function. If the reset type is not synchronous, the coder generates an error.

When you create the callback function, pass the infoStruct argument to the function. The argument contains the reference design and board information in a structure format. Use this information to enable custom validations on the DUT in your Simulink^® model.
