sldvlogsignals

Log simulation input port values

Syntax

data = sldvlogsignals(model_block)

data = sldvlogsignals(harness_model)

data = sldvlogsignals(harness_model, test_case_index)

Description

data = sldvlogsignals(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. sldvlogsignals records the logged data in the structure data.

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

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

Examples

Create a Harness Model by Using Logged Signals

Use logged signals to create a harness model to visualize the data.

Simulate the CounterB Model block, which references the sldemo_mdlref_counter model, in the context of the sldemo_mdlref_basic model. Then log the data:

openExample('sldemo_mdlref_basic');
data = sldvlogsignals('sldemo_mdlref_basic/CounterB');

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

load_system('sldemo_mdlref_counter');
harnessOpts = sldvharnessopts;
[~, harnessFilePath]  = ...
    sldvmakeharness('sldemo_mdlref_counter', data, harnessOpts);

Create a Test Case for a Model Block Component in a Closed Loop System

Log inputs to a model block component. Then simulate the closed-loop top model to log a test case with the model block interface.

openExample('sldv/GenerateTestsModelBlockComponentUsingDefaultSimulationExample');
data = sldvlogsignals('sldvexPowerWindow/power_window_control_system/control');

Input Arguments

model_block — Block path or handle to model

character vector | string scalar | Simulink.BlockPath object

Full block path name or handle or Simulink.BlockPath object to a Simulink Model block.

harness_model — Name or handle to a harness model

character vector | string scalar

Name or handle to a harness model that the Simulink Design Verifier software, sldvmakeharness, or slvnvmakeharness (Simulink Coverage) creates.

test_case_index — Simulate test cases

character vector | cell array of character vectors | string array

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

Output Arguments

data — Structure of logged data

structure

Structure that contains the logged data.
