Classes:

Direction

Define the possible directions for a given port.

__init__(name=None, properties=None, is_downto=None, is_scalar=None, lower_index=None, direction=None)[source]¶

Setup an empty port

Parameters:

name - (str) the name of this instance
properties - (dict) the dictionary which holds the properties
id_downto - (bool) set the downto status. Downto is False if the right index is higher than – the left one, True otherwise
is_scalar - (bool) set the scalar status. Return True if the item is a scalar False – otherwise.
lower_index - (int) get the value of the lower index of the array.
direction - (Enum) Define the possible directions for a given port. (UNDEFINED, INOUT, IN, – OUT)

property size¶

Returns number of pins in the port

Returns:: Returns size of port
Return type:: int

change_name(name)[source]¶

Change name of the port and corrosponding cable

Parameters:: name (str) – Name of the ports
