WebClock tree sink pin types can be manually overridden before invoking the create_ccopt_clock_tree_spec command with the following property setting: ... This gives rise to a negative source latency set at the clock root pin. Before CTS the average clock arrival time is zero and this is maintained after CTS via the source latency update. WebSink pins (balancing pins): Sink pins are the clock endpoints that are used for delay balancing.
