1)  Make sure cadence_patch.sh and sfk are executable. 
Move/copy all 4 files here (cadence.pat, cadence_patch.sh, README, 
sfk) to <cadence_install_dir>, e.g.: <cadence_install_dir>=/opt/cadence
On Ubuntu: sudo mv ~/patch/* <cadence_install_dir> where ~ is your home
directory, e.g. home/johndoe, and the patch directory is under your
home directory in this example, so ~/patch=home/johndoe/patch, and all 
files originally in the patch directory are now moved to the 
<cadence_install_dir> directory.

2)  On terminal command line, cd to <cadence_install_dir>, 
e.g. cd /opt/cadence and then run: sudo ./cadence_patch.sh <tool_dir> 
to patch each tool installed in the <cadence_install_dir>.
Examples:  sudo ./cadence_patch.sh INNOVUS152
	   sudo ./cadence_patch.sh IC617
	   sudo ./cadence_patch.sh MMSIM151
	   and so on.
