This perl script allows you to scale the liberty file timing and power numbers. You can also choose to change the timing or power of a particular cell also.
Code:
perl ~/bin/scaleLib.pl -lib ts40npksdstb02p1/ts40npksdst_ss1p08vn40c.lib *
# -scale <%age> *
# -out ./results/ *
# -cell "AN2" *
#perl scaleLib.pl -lib cell1 -tScale 0.9 -pScale 0.8 -cell "OR"
