Routing circuit and circuit having the routing circuit

A circuit, comprising:

• a plurality of integrated circuits, each of the integrated circuits has a plurality of signal channels;
• a plurality of signal terminals;
• and
• a routing circuit, coupled between the integrated circuits and the signal terminals, configured to route the signal channels of the integrated circuits to the signal terminals, the routing circuit comprising:
• a plurality of sequencers, each of the sequencers is coupled to the signal channels of a corresponding one of the integrated circuits to reconfigure an arrangement sequence of the coupled signal channels;
• and
• a processing circuit, coupled to the sequencers, the processing circuit comprising:
• a first distributor, configured to route the signal channels to the signal terminals in a group manner according to a control signal and based on the arrangement sequences of the signal channels of the integrated circuits that are reconfigured by the sequencers,
• wherein, each of the signal channels is routed to one of the signal terminals simultaneously, each of the signal terminals is a pin of the package, and a different control signal corresponds to a different arrangement sequence of the signal channels,
• wherein when the processing circuit routes at least two signal channels of the signal channels to a single signal terminal of the signal terminals, the processing circuit outputs a conflict situation signal to inform a user to change the routing situation between the signal channels and signal terminals, wherein the conflict situation signal represent which signal terminal of the signal terminals is routed with the at least two signal channels.
