Installing KLayout

Download and install KLayout from https://www.klayout.de/build.html. Builds should exist there for most common operating systems, choose the correct one for your OS. Otherwise you need to build KLayout yourself. We recommend installing KLayout without changing the installation directory location from default, as many KQCircuits features assume that KLayout specific files can be found there.

Note

For mac users:

KLayout can also be installed using the HomeBrew package manager, using terminal command brew install --cask klayout.

There might be issues on first time launch of KLayout with window: "klayout" cannot be opened because the developer cannot be verified. To fix this, find KLayout app using Finder, control+click KLayout, click Open, then in the warning window there should be option to Open.

KLayout is an actively maintained project with regular feature updates, bugfixes and stability improvements. We recommend using the latest version. KQCircuits is automatically tested using KLayout versions:

• 0.27.13

• 0.28.17

• latest version of 0.29

on the following platforms:

• Linux: Ubuntu 22.04 LTS, 64-bit

• MacOS: latest github image

• Microsoft Windows Server 2022, OS version 10

Note

KQC documentation uses Linux conventions and examples unless explicitly talking about Windows or MacOS. For example a Windows user should mentally translate path separator / to \, klayout executable klayout to %APPDATA%\KLayout\klayout_app.exe or the KLayout environment directory ~/.klayout to %HOMEPATH%\KLayout.
