Cadence - difference between a path and a wire

Hi everyone,

I'm trying to create a connection between a pin and a transistor source, but I don't understand the difference between a path and a wire and which I should use? Am I supposed to overlap the souce/pin with the wire/path - or just make it so it is touching?

The usual definition of a path is: a line with width and, possibly, overhang on the end points. If you use a path, the end points establish the connection; but, in reality, abuttment or overlap of the perimeter actually does it. It simplifies calculations if you use the end points because that's what is stored in the database.

This is sometimes further complicated by having the ability to have the path defining line define the right, left, or center of the path.
