Copy code
read_liberty -min $::env(LIB_FASTEST)
read_liberty -max $::env(LIB_SLOWEST)n

09/30/2020, 6:32 AMHi @Ahmed Ghazy..I tested the above.
The CTS runs successfully after including all the 3 libs( tt, ss and ff) in the or_cts.tcl script..
However to get the correct results I would have to manually change the ::env(CTS_MAX_CAP) to corresponding corner cap value and then do run_cts each time..
