A method of instantiating a leaf cell having various connections and designed to be called using a fixed syntax includes defining a template syntax different from the fixed syntax, setting default values for connections not designated by the template syntax, and mapping the template syntax to a hardware design language. The description of the leaf cell has values for the designated connections and non-designated connections. The non-designated connections have the default values. Another method includes instantiating a leaf cell using a first template syntax or a second template syntax. The second template syntax instantiates the same leaf cell as the first template syntax or the fixed syntax. In addition, more than one leaf cell, also known as a branch, can be instantiated using the template syntax. Articles of manufacture that include a computer readable media having instructions thereon for causing a suitably programmed system to execute one or more of the above methods of instantiating a leaf cell or leaf cells are also discussed.
