ZOTI-Graph¶
ZOTI-Graph is the core format for system models used between tools in the ZOTI project. Its purpose is to provide a minimal language to represent hierarchical graph-like structures, as well as an API to manipulate them or extract information.

Feature Highlights¶
ZOTI-Graph is for all intents and purposes a hierarchical graph format built on top of NetworkX. Its main purpose is to represent systems descriptions by annnotating its elements or by means of class inheritance and specialization. ZOTI-Graph models are intended to be used in the development of synthesis flows, hence the ZOTI-Graph tool features:
a generic API for parsing, extracting information and altering the structure of ZOTI-graphs. The API also exposes the internal NetworkX structure such that generic graph algorithms can be applied on ZOTI-graphs.
a script handler with utilities for setting up transformation flows on ZOTI-graphs.
(at the moment only) an specialized instance of the ZOTI-graph format to be used with the Genny synthesis flow, which represents system application views as graphs of concurrent actors. This format comes together with a parser, a set of sanity rules and a set of target-agnostic transformations compatible with the script handler.
For an overview discussion on the role of ZOTI-Graph and its position in a synthesis flow such as Genny please refer to the ZOTI project hub page.
The current implementation of ZOTI-Graph is as a Python library using mainly NetworkX for internal structure representation. For a feature list as well as installation and usage instructions, please refer to the project’s GitHub page.
