gds file

Hi all
Is there any way I can check the contents of a gds file BEFORE I
stream it in?
So that it list the layer name and gds number?

thanks in advance

I think if you stream it in to create a techfile rather than creating
new libraries/cell views then you should be able to get this
information, either from the techfile or the PIPO.log file. Select the
"TechFile" output option in the Import>Stream dialog window. There's
also an "ASCII Dump" option but I'm not sure what the output looks like,
or if it's easily human readable.

Maybe this can also be solved from within Cadence, but there are some
tools out there to view GDS2 files. An easy one can be found at
http://www.owlvision.org/ Other alternative would be electric at
staticfreesoft.com or Magic at opencircuitdesign.com. The last two are
not viewers, but layout tools that can import GDS2 and show layers.
Electric is java and need no compilation, magic is a bit "tricky" if
you don't have the required libraries installed.

is a little c++ library for looking at gdsii files as text dump. Last
time I used it it was a little bit slow.

 

If you have a calibre license , there is a tool called calibredrv
useage:
calibredrv -m gds_fname

Its VERY fast & easy to use.
