WieWeb software's main product is the layout editor CleWin. CleWin is a layout editor we designed in cooperation with the MESA+ Research Institute at the University of Twente and Deltamask, a mask making company.
The main advantage of CleWin is that it runs on a PC under Windows 2000/NT/XP/Vista/7. It is compatible with other layout packages because it uses the standard CIF and GDS-II file formats. Furthermore, CleWin can read and write the AutoCAD DXF, Gerber RS-274X and Electromask EMK file formats. High resolution PostScript is available as output format.
Because CleWin is also meant to be used by students a lot of attention is given to the user interface. CleWin is a hierarchical layout editor, i.e. a layout consists of symbols (also called cells) which may be nested. Editing a symbol in one place will change all other instances of the same symbol. The basic drawing primitives are boxes, circles, wires and polygons. These are the basic shapes that can be stored in the standard CIF format. Rings and spirals are automatically generated as wires. The latest version of CleWin fully supports true-type fonts. Complex polygons can be created using the boolean operations: merge, subtract, xor and intersect. For example: to create a box with a circular hole in it you just draw a box and a circle and select the subtract command.
Especially for MEMS devices some users like to use AutoCAD. Therefore the DXF file format was added. The default format is CIF because GDS-II only supports polygons and wires. When writing GDS-II other shapes like boxes and circels are converted into polygons.
CleWin supports a maximum of 256 layers.
CleWin (version 3) is available for 1450 euro. This price is for a small site-licence, i.e. a small company or a research group. For universities, updates are free and downloadable until the version number changes into 4.0. For companies, an update and support contract is offered by PhoeniX BV.

WieWeb software specializes in the development of technical, scientific and mathematical software.
Most of these products are custom made. Some of our larger projects include a parameter estimation program for semiconductor models and an automatic circuit-topology generator for so-called translinear electronic circuits.
Besides these "serious" applications we also have a lot of experience with creating screensavers. Some example screensavers will be downloadable from our downloads page in the near future.
The easiest way to get technical support for any of our products is by sending an e-mail to our support department:
You will always receive a reply within 24 hours. Bug reports are given a high priority: usually an update is available within one week.
Registered users of CleWin are entitled to free updates. We used to send these updates by e-mail, however due to the increasing number of customers this required quite some work from our side. Therefore, updates are now downloadable from our internet site. Just select the link below.
(Updated: April 25, 2003, Version 2.90)
Please note that you need a valid registration file in the CleWin directory, otherwise the software will not work. You should have received this registration file by e-mail.
At the moment we have two downloadable applications: a demo version of our layout editor CleWin and a layout viewer.
Both applications require Windows 95 or higher.
