Product Coupling
Product coupling allows a product to leverage the capabilities of other products in specialized areas. For example, coupling the Twin Builder System Simulator to Maxwell electromagnetic field simulation provides the accuracy benefit of full field simulation within the circuit simulation environment. Direct integration eliminates the need to translate models, saves time, and allows for greater accuracy.
In addition to the components provided with Twin Builder for use in Schematic Editor designs, Twin Builder schematics can also link to models created in external simulation software through special subcircuit coupling components. These coupling components may use data, extracted from full three-dimensional field data, in a Reduced Order Model (ROM) independent of the original model; or co-simulate with the model in its native product through a transient analysis.
For some ROM coupling components, the Twin Builder model obtained from the external product may be either a dynamic link (default) or static link.
- A dynamic link coupling component always checks the external product for updated ROM data before simulating.
- A static link coupling component only checks the external product if parameters on the coupling component changed since the ROM data was acquired.
During transient parametric co-simulations with Maxwell, the system adds the TBOptiVariation design variable to the Maxwell design in order to facilitate the simulation. This variable is read-only; do not change or delete its value.

You must recreate certain dynamic coupling models created before 2022 R1 in order to utilize the new functionality of using actual pin names in partner designs.
The model types are:
-
Q3D state space and Equivalent circuit links.
-
Maxwell Dynamic Magnetostatic and Electrostatic links.
-
Maxwell Eddy current links.
-
HFSS dynamic link.
Simulating designs with these components unchanged results in errors and unpredictable results. You can delete and recreate the component to fix this issue.
