This is a rather vague question - I can't even guess what you're hoping to get back as an answer or what your question means. My assumption is that you must be a student, in which case you should speak to your tutor or supervisor.

Regards,

Andrew.

In general, a "port" is a point of connection of a net to the "external world".
The "external world" may be a higher hierarchy level cell/design, or a pad, or a pin of a chip/package.

The term "port" is use din both digital and analog designs.

In layout, "port" is often called "pin", which creates some confusion - because the term "pin" is often used for device instance terminals/pins.
