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

oBalance 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.

• Check Latency:

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

• Do Useful Skew:

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

ICC2: clock_opt has options to enable useful skew,
