An Interface Control Document (ICD) tables describes the interfaces between systems or/and subsystems. That helps to ensure a compatibility between system components.
The purpose of Whitebox ICD Table is to show how Parts are connected via Ports/interfaces. This table collects all Parts of the context element. Those Parts are connected through the Ports/interfaces using Connector relationship. You can visually identify what kind of Ports/interfaces (Port A and Port B) and flows (Item Flow) are used to connects two Parts (Part A and Part B).
In the row 1, the Part Controller sends the control signal to the Part Boiler through the Ports b and c. The Controller receives the Status signal from the Boiler through the Ports c and b. In the row 2, the Part Controller sends the flow Elec Powerto the Part Boiler through the Ports bp and p in.
A Whitebox ICD Table consists of the following columns.
A row number.
Displays a Part that is connected with Part B.
Displays a Port that is connected with Port B.
Port A Features
Displays all the properties of the Port A.
Displays the flow kind and its direction which flows through the Connector between two Parts (Part A and Part B).
