Coupling component placement and parametrization - TLM based couplings

This section describes the TLM coupling component placement procedure and provides some general rules and tips for successful partitioning.

Correct placement and parametrization of coupling components is crucial for simulation stability and accuracy. There are a few steps that can help in correct circuit partitioning:

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, it is recommended to use the bilinear discretization method, but if the TLM inductance (capacitance) is relatively small, trapezoidal discretization can be used. TLM coupling is based on bilinear discretization and is more robust than Ideal Transformer coupling. TLM coupling in combination with the bilinear (trapezoidal) discretization method guarantees stability in most practical use cases, so there is no need for additional stability analysis.
