# DESIGN OBJECTIVE for UCA (or banks in NUCA)
-design objective (weight delay, dynamic power, leakage power, cycle time, area) 0:0:0:0:100

# Percentage deviation from the minimum value 
# Ex: A deviation value of 10:1000:1000:1000:1000 will try to find an organization
# that compromises at most 10% delay. 
# NOTE: Try reasonable values for % deviation. Inconsistent deviation
# percentage values will not produce any valid organizations. For example,
# 0:0:100:100:100 will try to identify an organization that has both
# least delay and dynamic power. Since such an organization is not possible, CACTI will
# throw an error. Refer CACTI-6 Technical report for more details

# By default CACTI considers both full-swing and low-swing 
# wires to find an optimal configuration. However, it is possible to 
# restrict the search space by changing the signaling from "default" to 
# "fullswing" or "lowswing" type.
