Common errors

error ModuleNotFoundError: No module named 'klayout' ↓

cause KLayout Python package not installed

fix

Install KLayout: pip install klayout

Use import doweb and access as doweb.xxx, or only import directly if documented.

Warnings

breaking KLayout API differences: doweb may not support all KLayout API features; expect discrepancies in layer properties and cell operations. ↓

fix Check doweb's documentation for supported API methods; use pure KLayout if full compatibility needed.

deprecated Python <3.11 no longer supported after v1.7.0 ↓

fix Upgrade to Python 3.11 or higher.

gotcha Concurrent use with other KLayout wrappers may cause import conflicts ↓

fix Ensure only one KLayout API implementation is imported at a time.

Quickstart

Basic usage: import doweb to activate KLayout backend, create a gdsfactory component, and export to GDS.

import gdsfactory as gf
import doweb

# Create a simple component
c = gf.Component('test')
c.add_polygon([(0,0), (10,0), (10,10), (0,10)], layer=0)
c.write_gds('test.gds')
print('GDS written with doweb backend')
