Sequence generator and design method thereof

The invention provides a sequence generator and a design method thereof. The sequence generator and the design method of the sequence generator are applied to the field of integrated circuit design. A clock and converting control module caches a specified sequence through a sequence buffering and generating module and configures starting of a sequence generating access; the specified sequence in the sequence buffering and generating module is controlled, generated and sent by a sequence generating and controlling register; when the specified sequence is transmitted through a sequence selecting and controlling module, a sequence selecting and controlling register controls a selected target sequence and outputs the sequence. The sequence generator and the design method of the sequence generator solve the problem of large difficulties in a test of a high speed serial data transmission channel, the specified transmitted sequence can be fast and effectively controlled and generated in a chip, and the specified initial sequence can be controlled, generated and transmitted in the initialization phase.
