Methods of making connections in a Schematic
There are three levels of connectivity in a Schematic design: 'normal' drawn/shown connections, implied connections (two pins connected but not all the connection drawn to declutter the design) and implied connections based on net name only.
- Normal connections are drawn by using Add Connection. Draw between the two (or more) pins required. The full connection is shown on the design.
- Implied connections are split into two types but use the same mechanism. The first is where part of the connection may be drawn and either left on 'free space' or ended on a Schematic only Symbol such as a TO/FROM Symbol. The net would be named. At the 'other' end, the same would be made, and it would have the same net name. Although it doesn't physically connect, the connection is implied by using the same net name. This is how power and ground is denoted but this method can be used for other connection types.
- Method two is where there is no connection drawn (not even a 'stub') but where the pin at both ends is named using a net name. Each pin of the same net will be then connected together as 'implied'.
