get_all_designs_metrics_openlane_v2(output_directory: piel.types.PathTypes, target_prefix: str)[source]#

Returns a dictionary of all the metrics for all the designs in the output directory.

Usage:

```python from piel.tools.openlane import get_all_designs_metrics_v2

metrics = get_all_designs_metrics_v2(

output_directory=”output”, target_prefix=”design”,

Parameters:

  • output_directory (PathTypes) – The path to the output directory.

  • target_prefix (str) – The prefix of the designs to get the metrics for.

Returns:

A dictionary of all the metrics for all the designs in the output directory.

Return type:

dict

read_metrics_openlane_v2(design_directory: piel.types.PathTypes) → dict[source]#

Read design metrics from OpenLane v2 run files.

Parameters:

design_directory (PathTypes) – Design directory PATH.

Returns:

Metrics dictionary.

Return type:

dict

run_openlane_flow(configuration: dict | None = None, design_directory: piel.types.PathTypes = '.', logic_implementation_type: piel.types.LogicImplementationType = 'combinatorial', parallel_asynchronous_run: bool = False, only_generate_flow_setup: bool = False)[source]#

Runs the OpenLane v2 flow, creates a custom configuration according to the type of the digital logic implementation.

Parameters:

  • configuration (dict) – OpenLane configuration dictionary. If none is present it will default to the config.json file on the design_directory.

  • design_directory (PathTypes) – Design directory PATH.

  • parallel_asynchronous_run (bool) – Run the flow in parallel.

  • only_generate_flow_setup (bool) – Only generate the flow setup.

  • logic_implementation_type (LogicImplementationType) – Type of digital synthesis to determine the openlane build flow.

Returns:

Flow
