This is a plugin for LibreLane that integrates FABulous.

It provides two custom flows:

• FABulousTile - Used to harden a tile or supertile.
• FABulousFabric - Used to stitch the tiles into a fabric.

Example tile libraries can be found in this repository: https://github.com/mole99/fabulous-tiles Examples of fabrics using these tile libraries can be found under: https://github.com/mole99/fabulous-fabrics

The config.json needs to be placed in the same directory as the tile.csv file.

• Set DESIGN_NAME to the name of the tile, e.g. LUT4AB.
• Set CLOCK_PORT to the clock port of the tile.

Additional configuration variables:

• FABULOUS_EXTERNAL_SIDE: Optional[Literal["N", "E", "S", "W"]] The side of the macro at which the external pins are placed.
• FABULOUS_SUPERTILE: Optional[bool] Is the tile a supertile?
• FABULOUS_TILE_DIR: Path Path to the tile directory where the tile CSV file is located.

• Set DESIGN_NAME to the name of your fabric.
• Add your models and custom cells to VERILOG_FILES, e.g. ["models_pack.v", "custom.v"].

Additional configuration variables:

• FABULOUS_FABRIC_CONFIG: Path The fabric configuration CSV file. It includes the tile map of the fabric, the parameters, and paths to the tiles.
• FABULOUS_TILE_LIBRARY: Path The path to the tile library.
• FABULOUS_TILE_SPACING: Optional[Decimal] The spacing between tiles.
• FABULOUS_HALO_SPACING: Optional[Tuple[Decimal, Decimal, Decimal, Decimal]] The spacing around the fabric. [left, bottom, right, top]
• FABULOUS_SPEF_CORNERS: Optional[List[str]] The SPEF corners to use for the tile macros.
