Coupling component placement and parametrization - TLM based couplings
This section describes the TLM coupling component placement procedure. Some general rules and tips for successful partitioning are given. Placement of the coupling components is shown through some common use cases.
- Check if there is a need for
circuit partitioning
- identify which components have to be in different sub circuits (different cores or devices)
- Place the coupling
components
- Find the best spot for the coupling
- Determine the correct coupling parameter value
When a TLM coupling is used, the simulation step cannot be set to Auto option, therefore it has to be defined explicitly. It is recommended to use bilinear discretization method, but if TLM inductance (capacitance) is relatively small, trapezoidal discretization can be used. TLM coupling is based on bilinear discretization and is more robust than the Ideal Transformer coupling. TLM coupling in combination with bilinear (trapezoidal) discretization method guaranties stability in the most of practical use cases, so there is no need for additional stability analysis.
