Re: GDSII files

Hi

Why you want to read the GDS files?

Generally GDS-II files contains the co-ordinate info in a specific format which can be used in Mask preparation. We need different [approx 18 msks] for a typical CMOS process. GDS-II files are given as input to E-Beam masking machines. These files can not be read as they are of not readable format. GDS files are mainly for fab purpose.

All the best.

    you do not have to share your discouraging opinions if you do not know the answer. There are many reason one needs to work with layout scripts such as merging cells and automation of layout

Re: GDSII files

Though you really dont want to read the GDSII files, but if want to view the graphical output of the GDSII, as in the polygons and their locations, you can use a tool which goes by the name "qckvu" by artworks.
Follow the link and know more.
