Four worked buying briefs
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. |

Scope and architecture
Simscape and Simcenter Amesim both support physical system modelling with component-based workflows. Simscape sits within the Simulink environment; Amesim uses its selected Siemens libraries and configuration. Test the required domains, components and model handover before choosing.
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 Simscape, include base products, required physical libraries, compute and support. For Simcenter Amesim, include application, required 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.
