1. A method comprising:
determining, by a main controller, measured delay time associated with a first cluster, the first cluster coupled with a second cluster in a daisy chain in a manner that the main controller communicates with the second cluster through an isolated interface of the first cluster;
determining, by the main controller and based on the measured delay time, a propagation delay associated with the first cluster;
generating, by the main controller, a message to the second cluster which includes a command to be executed by the second cluster; and
sending, by the main controller through an isolation interface of the main controller, the message to the second cluster based on the determined propagation delay to execute the command to actuate the second cluster synchronized to a switching clock of the main controller.
