Methods and systems provide creating and reporting of path annotations and renaming a state node using the path annotations for high level synthesis (HLS). In an embodiment, a method to annotate a state node includes identifying labels and pragmas specified in a high-level language input model for wait statements and function calls, and can also accommodate loops. In an embodiment, a method to display and/or report annotation information for a given state node includes displaying a state node name, an associated path annotation, and/or an associated hierarchical path. In an embodiment, a method to rename a state node based on a user-specified name includes using annotation information to locate a target state node and associating the target state node with the user-specified name or an automatically-created name based on the user-specified name. In an embodiment, a name specified for a state node can persist through successive runs of an HLS tool.
