#alpha and beta parameters for modeling intra-cell routing efficiency and gamma parameter to model I/O pin-access requirement(details in /doc/Pub_Full_8pages.pdf section II-C). Current values are based on Nangate open-cell library. Automated method to estimate these parameters based on cells under test will be provided later on. Please do not modify the following values for now. 

#Gamma parameter for considering pin access in congestion
