# SKY130_for_KLayout
## KLayout (version 0.27 or higher) technology files for Skywater SKY130
* SKY130.lyt : technology and connections description
* SKY130.lyp : layers color and shape description
* SkyWater SKY130 Design Rules.odt : SKY130 Design Rules in LibreOffice Writer format (compatible Word)
* SkyWater SKY130 Layers Reference.odt : SKY130 layers description in LibreOffice Writer format (compatible Word)
* drc/drc_sky130.lydrc : DRC script
* lvs/lvs_sky130.lylvs : LVS script (coming soon, so far only for MOSfet)
* def-lef/layermap.txt : layermap for the import_def.rb file : need to add in the config.mk file a line :
`export GDS_LAYER_MAP = ../../../../$(PLATFORM_DIR)/layermap.txt`
Within KLayout, create the technolgy SKY130 by the menu : **[Tools]-[Manage Technologies]**
Then press + at the bottom left, you will add a new technology that you can call : _SKY130_
Then, you can copy the file **SKY130.lyp**, **SKY130.lyt** and the 2 directories **drc** and **lvs** of that repository in your directory :
`$HOME/.klayout/tech/SKY130 (under Linux)`
`#HOMEDATA#/klayout/tech/SKY130 (under Windows)`
Due to few **SKY130 GDS** cases found and tested, the DRC/LVS files have not been extensively tested and still probably have bugs for some cases.
It was tested on the GDS and spice netlists of the LIB_CASES directory.
The more we can publish **SKY130 GDS** files, the better those DRC/LVS files.
At that stage, the GDS needs another checks before tape-out.
