The OpenCellLibrary is a physical design kit (PDK) for an Integrated Circuit design with the LayoutEditor. It is not intended for real IC fabrication but rather for educational and demontration use. Technology setup and standard cells are based on the OpenCellLibrary published by Nangate. It was modified for adaption to the LayoutEditor and to make it more realistic to a real design kit. It has been extended with parametric cells, symbols, design rule check macros, etc. to make it a complete PDK for the LayoutEditor and as a template for any new LayoutEditor PDK. Please read Nangate's copyright on the library before using it outside any educational purpose.
The only setup required is a layer setup. This setup is triggered automatically with the use of parametric cells. It is recommended to trigger this setup manually before starting the use the library. This can be done by calling a macro which is located in the main menu under Utilities/Technology/openCellLibrary/layer setup. This setup macro is optimized for the transparent PaintEngine. To switch to this PaintEngine a restart may be required. Add the OpenCellLibrary by hand, if it is not present in the SchematicEditor (AddLibrary). The library is stored in the folder library/openCellLibrary. The exact location is platform dependent.
The Open Cell Library is intended for use by universities, other research activities, educational programs and Si2.org members. However allowed, the Open Cell Library is not intended for commercial use. If you use the Open Cell Library for demonstration of commercial EDA tools it is required to mention, indicate that the library was developped by Nangate.
