Ground Definition
Grounds are a special component in the Mason library. As an unrelated side note, opens are implicit if a connection to a net is not made.- GND- Chassis ground
The Mason library has an RF Ground, which is not necessarily the ground net. For example, a power line with 3V on it is also an RF Ground. You can define a net to have a name (such as "3V_pwr") and use this component to enforce the RF ground.
To define an RF ground that is actually the ground net, use the ground symbol located in the toolbar above the schematic (second from the right).
