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.
  Rats will be displayed.
  Connect the route according to the Rats.

After placement, connection can be done using Add Net.
