 * Industrial library: the .lib file which define technology  
 *                     This is ubiquitous in commercial vendors
 *                     For industry library, we allow users to define
 *                     process corners.
 * Academia library: the .pm file which define technology 
 *                   This is mainly used in PTM-like technology library 
 * PTM is the Predictive Technology Model provided by the Arizona
 * State University (ASU). Available at ptm.asu.edu
