Creating and quering a CCI database...

I have a weird issue. In the past, I was able to create a CCI database by editing my LVS deck to change the line MASK SVDB DIRECTORY "svdb" QUERY to MASK SVDB DIRECTORY "svdb" CCI QUERY. As long as the LVS run completed (lvs clean), I then had the CCI data to work with using a command like this:

     calibre -cb -nowait -query ./svdb' topCell < cci-script.txt > query.log

where topCell was the top cell in the layout and cci-script.txt was the list of stuff I wanted to be generated with the query.

 

So, I'm not sure when this stopped working, but with the 2013.1_14.11 of Calibre, I get the following dumped into the query.log file:

Can't open PHDB database in "./svdb case0_base"
Can't open XDB database in "./svdb case0_base"

 

Anyone have any ideas on what I might be doing wrong? It seems odd that calibre cannot read databases it just created as I get this error message whether I give it a scrpt to read or not. Also, the LVS run is clean and the log file shows calibre lvs writing to the phdb and xdb files. They certainly exist in the .svdb directory.

 

Thanks,

Dave
