Concepts

This section describes how NoHAL’s editor objects map to the exported HAL output.

In This Section

• Component: component instances, exported instance paths, export namespace/stage, and setp.
• Sheet: root/system sheets, sheet definitions vs instances, ports, and path scope.
• Wiring: connections, labels, ports, and how net names are chosen during export.
• Threading: sheet thread outputs, root binding to project HAL threads, and addf expansion order.
• Component Store: built-in library, manual sources, and custom component definitions.

Mental Model

Export is assembled from these parts:

1. Components produce exported instance paths and pin paths, plus optional setp and addf.
2. Sheets provide hierarchy (path prefixes), boundaries (ports), and local scheduling (thread outputs + queue).
3. Wiring produces net lines by grouping connected endpoints.
4. Threading produces addf lines by expanding each sheet’s queue through subsheets.
5. The Component Store provides the component definitions used by the project (built-in, imported, and custom).
