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?

    My assumption is that the stream file that you are reading is either corrupted, or it is using some non-standard extensions (that seems less likely). According to the documentation, record types 60-69 were used by an old Calma GDSII application called Custom Plus and are not used by Virtuoso - so it seems unlikely they would be used in any modern application.

    Where did the stream file originate from? Has it been compressed mistakenly?

    Perhaps you need to contact customer support.

    Kind Regards,

    Andrew.
