Intro

For running this DRC examples you will require to open Klayout and make sure you have klive extension installed.

as well as gdsfactoryPlus

pip install gdsfactoryplus --upgrade

Then you need to configure your PDK, URLs and Keys to point to the correct deployment.

To do this, ensure you create a config file in ~/.gdsfactory/gdsfactoryplus.toml with the default gdsfactoryplus settings. For example:

[tool.gdsfactoryplus.api]
key = "<your-api-key>"

Note

You can also use this as a template for your own global gdsfactoryplus config or your per-project pyproject.toml file.

A cell with errors

Let's create a GDS with some DRC errors, run DRC on the remote server and review the results locally in your computer.

@gf.cell
def width_min(size=(0.1, 0.1)):
    return gf.components.rectangle(size=size, layer="WG")

c = width_min()

Check DRC

gdspath = c.write_gds()
lyrdb = gfp.check_drc(gdspath)
lyrdb_path = Path("errors.lyrdb")
lyrdb_path.write_text(lyrdb);

uploading '/tmp/gdsfactory/width_min_S0p1_0p1.gds'...
