Bus Node Property: Property number 9

The bnode property identifies the location of a ``bus connector'' which is used to specify multiple connections to a device or subcircuit. It may appear in subcircuit cell definitions and instance references.

5 9 id min_index max_index x y;

The id is a non-negative integer index used to identify the connector. For a given subcircuit, each bus connector will be given a unique id integer, starting with 0. The next two values are non-negative integers that specify the range of normal connection indices included in the bus connection. The final two fields specify the ``hot spot'' location. For cells, these may each be in the form pos:sypos, i.e., two colon delimited numbers. The first number applies in non-symbolic mode, the second applies in symbolic mode. For cell instances or when there is no symbolic representation, each field consists of a single number.
