Environment setup
cd ~/cadence/tech_dir mkdir calibre cd calibre mkdir drc lvs pex
source /usr/local/config/mentor_config/Calibre_2010.rc
Ensure that in the .cdsinit_tech there is a line
setenv MGC_HOME /path/to/Calibre/installation/directory
/usr/mentor/calibre_2010
Load Calibre interface into Cadence Virtuoso

load(strcat(mgc_home "/shared/pkgs/icv/tools/queryskl/calibre.skl"))
or
load( strcat( getShellEnvVar("MGC_HOME") "/lib/calibre.skl" ))
Load Calibre interface into Cadence Encounter
Invoke Calibre from the command line

Design Rule Check (DRC)
Create a Calibre DRC run directory runset,
cd ~/cadence/tech_dir/calibre/drc mkdir data rules runsets
cd rules cp /path/to/technology/calibre/drc/rule/file drc.rules.default
Layout Editor L ⇒ Calibre ⇒ Run DRC
Depending on your predefinite configuration a Load Runset File window may apperar at the Calibre startup
Spiegare cos'e' un runset file
Modify this preferences through Setup ⇒ Preferences..
deselect the Show Load Runset dialog in the Startup tab and check the Don't load a runset option.
Specificare il path completo del rules file del tipo
~/cadence/tech_dir/calibre/drc/drc.rules
e come run directory mettere
~/cadence/tech_dir/calibre/drc/data
To start the DRC left click the Run DRC button
Compare una DRC Summary Report window
Working with runsets
