Simulink vs Simscape
Simulink provides the block-diagram environment for dynamic system models. Simscape adds physical component-network modelling within that environment. These are complementary products: decide whether the model needs physical networks and then scope the required Simulink and Simscape licences.

Seven differences that change the shortlist
| Buying question | Simulink | Simscape |
|---|---|---|
| Modelling role | Dynamic system modelling environment | Physical system modelling tools |
| Model representation | Block diagrams and hierarchical models | Connected physical component networks |
| Simulation context | System behaviour and model-based design | Multidomain physical systems |
| Base environment | MATLAB and selected Simulink configuration | Simulink environment and required base products |
| Integration boundary | Additional physical modelling and code generation products are scoped separately | Specialist Simscape libraries can require additional licences |
| Evaluation focus | Time dynamics, model structure and required add-ons | Physical domains, component assumptions and supported solvers |
| Cost components | Base products, add-ons, compute and deployment rights | Base products, required physical libraries, compute and support |

These are hypothetical scenarios with explicit assumptions. They do not establish equal capabilities, measured usability or a negotiated price.
| Requirement | Proposed exercise | Accept when |
|---|---|---|
| Model scope | Describe the physical domains, units and interfaces of one copied reference case. | The chosen tools represent the required physical assumptions. |
| Reference behaviour | Run the defined model against independently specified expected behaviour. | Results and tolerances are reviewed by the responsible engineer. |
| Model exchange | Move one supported model or result through the required integration. | Units, parameters and interface assumptions remain documented. |
| Licence boundary | List the base products, libraries, modules and execution resources used. | The complete configuration is available under the intended licences. |
Model scope
Can the team describe the physical domains, units and interfaces of one copied reference case?
Simulink: With Simulink, describe the physical domains, units and interfaces of one copied reference case.
Simscape: With Simscape, describe the physical domains, units and interfaces of one copied reference case.
The chosen tools represent the required physical assumptions.
Reference behaviour
Can the team run the defined model against independently specified expected behaviour?
Simulink: With Simulink, run the defined model against independently specified expected behaviour.
Simscape: With Simscape, run the defined model against independently specified expected behaviour.
Results and tolerances are reviewed by the responsible engineer.
Model exchange
Can the team move one supported model or result through the required integration?
Simulink: With Simulink, move one supported model or result through the required integration.
Simscape: With Simscape, move one supported model or result through the required integration.
Units, parameters and interface assumptions remain documented.
Licence boundary
Can the team list the base products, libraries, modules and execution resources used?
Simulink: With Simulink, list the base products, libraries, modules and execution resources used.
Simscape: With Simscape, list the base products, libraries, modules and execution resources used.
The complete configuration is available under the intended licences.
Scope and architecture
Simulink provides the block-diagram environment for dynamic system models. Simscape adds physical component-network modelling within that environment. These are complementary products: decide whether the model needs physical networks and then scope the required Simulink and Simscape licences.
Block-diagram models, physical component networks and field-based multiphysics models describe different levels of a system. Simscape extends the Simulink environment rather than replacing its base licence. Select the actual physical domain, solver and required modules.

Cost and migration planning
For Simulink, include base products, add-ons, compute and deployment rights. For Simscape, include base products, required physical libraries, compute and support. Define the same task, inputs, required outputs and operating environment, then confirm current terms for the actual software configuration.
Rebuild one authorised reference model with documented units, parameters and boundary conditions. Compare the result against independently specified expectations, then have the responsible engineering team approve model validity and deployment before production use.
Questions before you choose
How should we choose between Simulink and Simscape?
Simulink provides the block-diagram environment for dynamic system models. Simscape adds physical component-network modelling within that environment. These are complementary products: decide whether the model needs physical networks and then scope the required Simulink and Simscape licences.
Which costs belong in the comparison?
For Simulink, include base products, add-ons, compute and deployment rights. For Simscape, include base products, required physical libraries, compute and support. Define the same task, inputs, required outputs and operating environment, then confirm current terms for the actual software configuration.
What should we validate before a production move?
Rebuild one authorised reference model with documented units, parameters and boundary conditions. Compare the result against independently specified expectations, then have the responsible engineering team approve model validity and deployment before production use.
