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 geometries and layers to incorporate last minute changes.

GTlayer translates elements of aย  GDSII or OASIS layout database from a layer to another for a safe and easy last minute adjustment:

  • Translation from one layer to another for process migration from one generation to the next or from one foundry to another
  • Remove all objects in a specific layer / datatype to clean databases from unexpected data, such as recognition layers and non-manufacturable layers
  • Flattens database


GTlayer, mainly used in multi-chip assemblies and chip information extractions creates a new version of the layout database in minutes.

GTlayer 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.

GTlayer can be run through an intuitive Graphical User Interface or on the command line for automatic processing and easy inclusion in an existing flow.


  • Simplify process migration
  • Safe ECO changes
  • Fast revisions of chips and multi-chip assembly


  • Converts single or multiple layers
  • Removes useless layers
  • Flattens database
  • Directly operates on gzipped files
