Cell replacing tool
As the cost of design and mask sets have dramatically increased with the most advanced processes, it is critical for design teams and mask data preparation teams to include robust and repeatable layout manipulation tools in their flow in order to increase their productivity and remove risk of error.
During the DFM and Mask Data Preparation, designers may have to switch entire cell hierarchies in order to incorporate last minute changes.
GTreplace extracts any cell hierarchy from a GDSII or OASIS layout database and replaces it safely for a safe and easy last minute adjustment:
- ECO changes
- ROM code replacement
- Revision code replacement
- Programmable customization
GTreplace, mainly used in multi-chip assemblies and chip information extractions creates a new version of the layout database in minutes.
GTreplace is fully integrated in XYALIS layout manipulation suite and in XYALIS Mask Data Preparation solution. It handles standard layout: GDSII, OASIS and works directly on compressed of gzipped files.
GTreplace can be run through an intuitive Graphical User Interface or on the command line for automatic processing and easy inclusion in an existing flow.
- Safe ECO changes
- Fast revisions of chips and multi-chip assemblies
- Parameterized renaming style
- Bounding box checking
- Recursive call checking
- Removes all unused cells from GDSII/OASIS database
- Directly operates on gzipped and compressed file
