Port Setup in HFSS 3D Layout

When you specify an excitation for an HFSS 3D Layout structure, HFSS 3D Layout uses the principle of linear superposition to calculate the solution. The signal on each port and mode is solved for separately. HFSS 3D Layout sets the signals on all non-zero modes and generates a solution. This procedure is repeated with each port until a solution is generated for each.

HFSS 3D Layout offers a variety of ports. HFSS attributes and sizing information are all available as properties. This includes port sizes, chosen return paths, and verifying port types as being chosen for the particular application that is being designed and simulated.

HFSS 3D Layout automates the following processes to ensure the successful setup of ports:

• Automatic reference location (with override option)
• Automatic port-geometry generation (with sizing override option)
• Automatic terminal identification
• Numerous pre-solve validation checks, with messaging to alert you when something is wrong

The following topics describe the setup and usage of the various ports available in HFSS 3D Layout.
