Whenever you want to use OpenLane, nix-shell in the repository root directory and you’ll have a full OpenLane environment. The first time might take around 10 minutes while binaries are pulled from the cache.\n\nTo quickly test your installation, simply run \n```\nopenlane --smoke-test\n``` \nin the nix shell.\n\n# For more details and running the openlane flow this [openlane](https://openlane2.readthedocs.io/en/latest/getting_started/newcomers/index.html#running-the-default-flow) documentation","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnishit0072e%2Fopenlane-flow","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnishit0072e%2Fopenlane-flow","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnishit0072e%2Fopenlane-flow/lists"}
