Layout Software

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. Since we started with the development of CleWin, almost 15 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 25 countries, both by companies and universities.

CleWin runs on a PC with Windows NT, 2000, XP, Vista or Windows 7. It is compatible with other layout packages since it uses the standard CIF and GDS-II file formats. Furthermore, CleWin can read and write the AutoCAD DXF, Gerber RS-274X and Electromask and Mann file formats. High resolution (Encapsulated) PostScript is available as output format. Bitmap files can be easily imported using the separate bitmap import utility.

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. CleWin shows a hierarchical list of all symbols in a design, so that each symbol definition is directly accessible for editing. Furthermore, the hierarchical list provides a clear overview of the file structure and the dependencies between the defined symbols. In version 4, a powerful scripting engine was added, that allows the generation of objects using four different languages: C, Matlab, the MaskEngineer language and Lua. Scripts are especially useful for complex, parametric designs, but also for relatively simple tasks like automatic numbering of chips.

The most important features of CleWin include:

• Hierarchical tree-view of the design giving direct access to every symbol definition.
• Improved polygon and wire editing, allowing adding and deleting nodes by simple mouse clicks.
• Full support of true-type fonts.
• Advanced grid with the possibility of using a different grid spacing in the horizontal and vertical direction.
• Snap to grid, guidelines and/or 45 degree angles.
• Any CIF or GDS-II file can be used as symbol library.
• Powerful scripting possibilities in C, MatLab (requires a separate MatLab license), MaskEngineer and Lua.
• Built-in area calculator and cross-section viewer
• Unlimited undo function.
• 1 nanometer resolution.

CleWin version 4 is available in two editions: the standard edition for Euro 1950, and the pro edition for Euro 2250 (small site license). For a complete price list, please download the pdf flyer or contact us by e-mail.

For companies, an update and support contract is offered by PhoeniX BV.
