Connection Point

Connection Point is a function for setting one point as a reference potential. It is also referred to as a "Single Point Ground" or "Single Point Earth".

By combining two different GNDs into a single [Earth Point], it is possible to minimize the potential difference, which is a countermeasure for noise.
Using this function, schematic and PCB affinity is improved, and the single earth portion is considered by the DRC of the PCB design side, so a visual check is no longer needed, which results in greatly reducing routing work.

Connection Point Usage Example

Drawing a Connection Point
The following is the operation for a Connection Point.
(1) Select [Draw] >> [Connection Point].
(2) Input a Connected Net Name, and then click "OK".
  * To input multiple Net Names for a connection, input by entering a line break.
(3) Click on the coordinate where you want to place it.

=> Connection lines will be displayed.
(4) Connect the route according to the connection lines.

After placement, connection can be done using Add Net.
