Command to balance two clock trees? Command to check latency? Command to do useful skew?

o   Balance Two Clock Trees:

·         Innovus: create_skew_group -name <group_name> -clocks {<clock1> <clock2>}

·         ICC2: set_clock_balance_points can be used to define common points for balancing.

o   Check Latency:

·         Innovus/ICC2: The command report_clock_timing -type latency is used.

o   Do Useful Skew:

·         Innovus: Enabled by default during ccopt_design. Can be controlled with setUsefulSkewMode.

·         ICC2: clock_opt has options to enable useful skew,
