Numerical Equivalence Testing

Compare results from model simulation and generated code by using test benches

Test numerical equivalence between your model and generated code by comparing simulation results to test bench results. You can generate a test bench during code generation. The test bench contains the model simulation output results, which are then compared to the generated code output results. The generated code output results are the results from running the generated code in the target IDE.

Topics

Generate Code That Has Multiple Test Benches
Provide multiple signal groups as subsystem input so that multiple test benches are generated for code verification.
Author, Manage, and Execute Simulation-Based Tests of Generated Code
Workflow for using Simulink Test with PLC Coder.

Featured Examples

Verify Generated Code by Using Cosimulation

Verify your generated code by using cosimulation. The generated code and testbench run on a Codesys software-based programmable logic controller (soft PLC). The Simulink® model uses Open Platform Communication Unified Architecture (OPC UA) to communicate with and retrieve the cosimulated data from the soft PLC. The Simulink model verifies the generated code by comparing the model simulation results to the cosimulated soft PLC results.
