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!
#specifies GDS property values for attributes, corresponding to nets, instances and devices
gds netprop number 5
gds placeprop number 6
gds devprop number 7
The descriptions of those commands are in the Calibre Query Server Manual in the "Annotated GDSII File Commands" section. They add property values to various objects in the AGDS output and all default to 1. If you don't use such properties, you can omit the commands from the script.
