Overview

This tutorial consists of two parts: a tutorial for the DRC feature of KLayout and another one for the new layout-to-netlist feature. While the DRC tutorial covers mature functionality available since a few years now, the layout-to-netlist feature is brand new and still under development. The tuturial for this part will show the use cases that are available already and prepares the basis for the next level of verification support.

Both tutorials are based on a virtual technology with a design manual document and sample layouts. You'll find the samples, scripts and design manual on GitHub at

https://github.com/klayoutmatthias/si4all

To work through the DRC tutorial part you will need a standard KLayout installation (version 0.25.x - 0.25.8 is recommended). Binary distributions are available for a variety of systems here:

https://www.klayout.de/build.html

For the layout-to-netlist tutorial, you'll need a build for the development branch (master) from https://github.com/klayout/klayout. Prebuild binaries can be found here along with current documentation links:

DRC Tutorial

For the tutorial you need the sample files. Get them from GitHub:

git clone https://github.com/klayoutmatthias/si4all

or download as .zip an unpack.

Start KLayout and include the DRC files, so you can use them easily:

  • Use Tools/Macro Development IDE
  • Select the "DRC" page
  • Right-click on the DRC column, chose "Add location"
  • Navigate to the "drc" folder and press Ok
  • Double-click "drc - NCC1701" it

For trying the DRC, a layout with a lot of DRC errors has been provided. Open (or drag and drop)

<si4all>/samples/drc_errors.gds

You can also load (or drag and drop) the layer properties file from

<si4all>/tech.lyp

Run the DRC by using the "Run" button from the macro development IDE.

When the DRC has finished, the Marker Browser will open. For a better visibility of the markers chose "Configure" and use these settings right.
