    %% Switching between Harness Configurations
%
% Switch test harness configuration for different verification objectives. 
% Copyright 2015 The MathWorks, Inc.

%%
% This example shows how to switch between various harness configurations
% during incremental component development.
% The example model counts the number of ticks and outputs the count. 
mdl = 'sltestSwitchHarnessConfigurationExample';
open_system(mdl);
sim(mdl);

%%
% Open the test harness |Counter_harness| attached to the |Counter| subsystem. 
% This test harness has been created using the *Prototyping* harness
% configuration.
% Open the test harness.
sltest.harness.open([mdl '/Counter'],'Counter_harness');

%%
% The test harness |Counter_harness| is not configured for the correct
% datatypes used in the main model. This can cause simulation errors. 
% Rebuild the test harness to ensure that the datatypes used in
% the test harness are the same as that used in the main model.
%
% Click the test harness badge in the test harness
% window. This opens the test harness properties dialog. 
% Set these properties:

%% 
% * Initial harness configuration:    Refinement/Debugging

%% 
% Click *OK*. The properties take effect the next time you open the test harness. 
% 
% To manually rebuild the test harness select *Analysis > Test Harness >
% Rebuild Harness from Main Model* or enter:
sltest.harness.set([mdl '/Counter'],'Counter_harness','RebuildWithoutCompile',false);
sltest.harness.rebuild([mdl '/Counter'],'Counter_harness');

%%
% The test harness now simulates without errors. To rebuild each time you open 
% the model, update the harness configuration using the test harness properties dialog or enter:
sltest.harness.set([mdl '/Counter'],'Counter_harness','RebuildOnOpen',true);

%%
% Close the test harness.
sltest.harness.close([mdl '/Counter'],'Counter_harness');

%%
% The counter modeled in the component under test can be reset with an external
% signal. Enter the following commands to create reset logic in the model.
