PostSWInterfaceFcn

Syntax

Description

PostSWInterfaceFcn registers a function handle for the callback function that gets executed at the end of the Generate Software Interface 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.PostSWInterfaceFcn = @my_reference_design.callback_PostSWInterface;

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_PostSWInterface, and is located in the reference design package folder +my_reference_design.

With this callback function, you can change the generated software interface model for the custom reference design.

This example code shows how to create the callback function. The function adds a DocBlock in the software interface model.

function [status, log] = callback_PostSWInterface(infoStruct)
% Reference design callback run at the end of the task 
% Generate Software Interface Model
%
% 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
% infoStruct.SWModelDutPath: the block path to the SW interface subsystem
%
% feature controlled by IPCoreSoftwareInterfaceLibrary
% infoStruct.SWLibBlockPath: the block path to the SW interface library block
% infoStruct.SWLibFolderPath: the folder path to the SW interface library
%
% status: process run status
%         status == true means process run successfully
%         status == false means process run failed
% log:    output log string


status = true;
log = '';
swDutPath = infoStruct.SWModelDutPath;
add_block(['simulink/Model-Wide', char(10), 'Utilities/DocBlock'], sprintf('%s/DocBlock', swDutPath), 'Position', [50, 50, 80, 80]);

end

In the HDL Workflow Advisor, when HDL Coder™ runs the Generate Software Interface task, it executes the callback function at the end of the task.

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 specify custom settings for software interface model generation.
