I generate the SVDB database for a design using Calibre nmLVS, and next step I need to generate the CCI database based on the SVDB. Basically I used the script below to generate the CCI data:
calibre -cb -nowait -query ./svdb TopCellName < CCI-SCRIPT.txt > query.log
TopCellName is the top cell name of the design in the source/layout. Here I used the CCI-SCRIPT.txt file to control Calibre during generation. In this file there are three commands that I am not sure what they mean and what the number stand for. Could anyone provide me more information? Will really appreciate that!
