Error while importing .gds in cadence IC 6.16

radiowaves

Hi,
I get the follwing error while importing a .gds file in cadence IC 6.16

ERROR (XSTRM-80046): You are trying to modify the tech database, but the tech database is not writable. Check the tech database file and parent directory permissions.

What is tech database? How to fix this?

    You could, but it's probably not a good idea.

    You could either go to the Geometry tab on the stream in form and turn off "Skip Undefined LPPs", or you could create a library which references your technology library (rather than attaches to it), and then any undefined layer purpose pairs will be added to the library's own incremental technology database. In other words, the previously known layer purpose pairs will be in the main technology library, but any extra undefine LPPs will be added to your local library's incremental tech db (which tops up the main tech library).

    Andrew.
