Blank Components
Understand the helper-only component scaffold included with the blank template.
The blank template starts with no public components. Its components/ package
contains only the shared scaffold:
| Module | Purpose |
|---|---|
__init__.py | Public project exports; initially __all__ = []. |
_utils.py | safe_cell_name() for deterministic names within the GDS length limit. |
_curves.py | S-bend point, tangent, envelope, and path-length helpers. |
_tapers.py | taper_polygon() and the TaperProfile type. |
These underscore modules are project-local implementation helpers, not components
to instantiate directly from a design. Define semantic layers in rosette.toml, then
use the shared component-authoring guide to
build and export the components your process requires.
If you want the complete starter catalog instead, initialize a project with the generic template. Do not copy the generic catalog into an established project without reviewing its layer, geometry, and process assumptions.
