Global Nodes (global)

Description

The global statement allows a set of nodes to be designated as common to the main circuit and all subcircuits. Thus, components inside subcircuits can be attached to global nodes, even though the subcircuit terminals are not attached to these nodes.

Any number of global nodes may be specified using the global statement. To do this, follow the keyword global with a list of the node names that you wish to declare as global. The first node name that appears in this list is taken to be the name of the ground node. Ground is also known as the datum or reference node. If a global statement is not used, 0 is taken to be the name of the ground node.

Ground is always treated as global even if a global statement is not used. Multiple global statements are supported.
