get_design_from_openlane_migration(v1, design_name_v1, ...)

This function provides the integration mechanism for easily migrating the interconnection with other toolsets from an OpenLane v1 design to an OpenLane v2 design.
get_design_from_openlane_migration(v1: bool = True, design_name_v1: str | None = None, design_directory: str | pathlib.Path | None = None, root_directory_v1: str | pathlib.Path | None = None)[source]#

This function provides the integration mechanism for easily migrating the interconnection with other toolsets from an OpenLane v1 design to an OpenLane v2 design.

This function checks if the inputs are to be treated as v1 inputs. If so, and a design_name is provided then it will set the design_directory to the corresponding design_name directory in the corresponding root_directory_v1 / designs. If no root_directory is provided then it returns $OPENLANE_ROOT/”<latest>”/. If a `design_directory is provided then this will always take precedence even with a v1 flag.

Parameters:

  • v1 (bool) – If True, it will migrate from v1 to v2.

  • design_name_v1 (str) – Design name of the v1 design that can be found within $OPENLANE_ROOT/”<latest>”/designs.

  • design_directory (str) – Design directory PATH. Optional path for v2-based designs.

  • root_directory_v1 (str) – Root directory of OpenLane v1. If set to None it will return $OPENLANE_ROOT/”<latest>”

Returns:

None
