Chapter 5<br />

Ports<br />

This chapter describes the five different types of ports used in <strong>Sonnet</strong>, how they<br />

are modeled and how to place or delete them in your circuit.<br />

The five types of ports used in <strong>Sonnet</strong> are the standard box-wall port, the co-calibrated<br />

internal port, the via port, the auto-grounded port and the ungrounded internal<br />

port.<br />

Port Type Overview<br />

As mentioned above, the five types of ports available in <strong>Sonnet</strong> are the standard<br />

box wall, co-calibrated internal port, via port, autogrounded port and internal ungrounded<br />

port. All ports in <strong>Sonnet</strong> are two-terminal devices. The box wall and cocalibrated<br />

port types are those used the majority of the time. Each type of port is<br />

described below.<br />

Box wall:<br />

• Most common type of port.<br />

• Positive terminal is attached to a metal polygon and the negative<br />

terminal is attached to the box wall (ground).<br />

• De-embedding is the most accurate for this type.<br />

• Used for connections to the periphery of your geometry.<br />
