Syntax

data = slvnvlogsignals(model_block)
data = slvnvlogsignals(harness_model)
data = slvnvlogsignals(harness_model,test_case_index)

Description

data = slvnvlogsignals(model_block) simulates the model that contains model_block and logs the input signals to the model_block block. model_block must be a Simulink® Model block.

data = slvnvlogsignals(harness_model) simulates every test case in harness_model and logs the input signals to the Test Unit block in the harness model. Generate harness_model by using the Simulink Design Verifier™ analysis, sldvmakeharness (Simulink Design Verifier), or slvnvmakeharness.

data = slvnvlogsignals(harness_model,test_case_index) simulates every test case in the Signal Editor block of the harness_model specified by test_case_index. slvnvlogsignals logs the input signals to the Test Unit block in the harness model. If you omit test_case_index, slvnvlogsignals simulates every test case in the Signal Editor.

Examples

This example shows how to log simulation data for a Model block and use the logged data to create a harness model and visualize the data in the referenced model.

Open the directory that contains the example files.

openExample('simulink/ExamineMultipleReferencedModelInstancesExample')

Open the model and log the signals for the CounterB block.

open_system('sldemo_mdlref_basic');
data = slvnvlogsignals('sldemo_mdlref_basic/CounterB');

Create a harness model for sldemo_mdlref_counter using the logged data and the default harness options.

load_system('sldemo_mdlref_counter');
harnessOpts = slvnvharnessopts
[harnessFilePath]  = ...
    slvnvmakeharness('sldemo_mdlref_counter', data, ...
    harnessOpts);

Input Arguments

collapse all

The full block path name or handle to a Simulink Model block, specified as a character vector or string.

Name or handle to a harness model that the Simulink Design Verifier software, sldvmakeharness (Simulink Design Verifier), or slvnvmakeharness creates, specified as a character vector or string.

Array of integers that specifies which test cases in the Signal Editor block of the harness model to simulate.

Output Arguments

Structure that contains the logged data.
