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 DFM and Mask Data Preparation  process engineers want to measure special structures when design engineers want to check the final layout of the chip. Both need to display large GDSII, OASIS, and MEBES layout databases with an easy layout editor which does not require large memory and disk space for full-chip display.

GOTviewer is a fast and easy-to-use layout editor for GDSII, OASIS, and MEBES layout databases :

  • Reads and display GDSII, OASIS, MEBES and JobDeck files.
  • Reads DRC error files with a user friendly error browser.
  • Save user selected views for a fast navigation.


GOTviewer is fully integrated in XYALIS layout manipulation suite and in XYALIS Mask Data Preparation solution.


  • Fast and easy display of layout databases
  • Reads and display GDSII, OASIS, MEBES and JobDeck files.
  • Allows mask data validation.


  • Possibility to filter unused data during GDSII/OASIS/Mebes input in order to furthermore reduce memory usage
  • Reads directly compressed or gzipped GDSII/OASIS/Mebes files with minimum memory, disk usage and no temporary file creation or speed impact
  • Hierarchical browser and navigation with selective hierarchical display to only view selected branches of the hierarchy tree
  • Reads DRC error files and offers a user friendly error browser.
  • “Where are you” function gives all the data regarding layers and hierarchy
  • “GoTo” function
  • Easy -to-use ruler, color and pattern selection, layer and data-type selection
  • Instantaneous redraw of saved views.
  • Smart handling of corrupted GDSII/OASIS/Mebes databases (multiple top cells, missing cells, …)
  • On-line help
