CleWin

What is CleWin?

CleWin is a layout editor that we designed in cooperation with the MESA+ Research Institute at the University of Twente and Deltamask, a mask manufacturing company. Since we started development of CleWin more than 20 years ago, the product has evolved from a simple editor to a powerful mask design tool. The product has been very successful over the years and is used worldwide in 35 countries in hundreds of companies and universities.

Since CleWin must also be used by students, a lot of attention is paid to the user interface. CleWin is a hierarchical layout editor, that is, a layout consists of "symbols" (also called "cells") that can be nested. Editing a symbol in one location changes all other instances of the same symbol. CleWin shows a hierarchical list of all the symbols in a design, so that each symbol definition is directly accessible for editing. In addition, the hierarchical list provides a clear overview of the file structure and dependencies between the defined symbols.

A powerful scripting engine has been added that allows you to generate objects using four different languages: C, Matlab, the MaskEngineer language, and Lua. Support for Python scripts has been added to CleWin. Scripts are especially useful for complex parametric designs, but also for relatively simple tasks such as automatic chip numbering.

System Requirements:

CPU: 1.8 GHz dual core processor

RAM: 2 GB

HDD/SSD: 50 GB of free space on main drive

Operating system: Microsoft Windows 8 32-bit, Microsoft Windows 7 32-bit and Microsoft Windows Vista 32-bit

It is compatible with other layout software as it uses the standard CIF, GDS-II and OASIS file formats. In addition, CleWin can read and write AutoCAD DXF format. High-resolution (encapsulated) PostScript is available as an output format. Bitmap files can be easily imported using the separate bitmap import utility.
