# Port excitation

Port excitation settings control which port simulations are run and which S-matrix elements can be inferred from symmetry.

# Run Only

run_only: Optional list of S-matrix indices that define which port simulations to run.

  • Options:
    • None: Run all simulations needed for the full S-matrix.
    • Selected entries: Run only the selected S-matrix entries.
  • Default: None

# S-Parameter Symmetry

element_mappings: S-matrix element mappings used to skip simulations whose results can be inferred from another matrix element.

Each mapping relates an input element, output element, and complex coefficient.
