In emulation systems having a plurality of chips, data communicated between the chips needs to be synchronized. A receiver chip may push or pull on incoming data from an emitter chip in order to synchronize it with a receiver clock. Unexpected latency on the link between the emitter and receiver chips may also be adjusted for.
