Routing circuit and circuit having the routing circuit

摘要

A routing circuit and a circuit having the routing circuit are provided. The circuit includes a plurality of integrated circuits (ICs), a plurality of signal terminals and the routing circuit. Each of the ICs has a plurality of signal channels. The routing circuit is coupled between the ICs and the signal terminals to route the signal channels to the signal terminals. The routing circuit has a plurality of sequencers and a processing circuit. Each of the sequencers is configured to reconfigure an arrangement sequence of the signal channels of a corresponding one of the ICs. The processing circuit is coupled to the sequencers and has a first distributor. The first distributor routes the signal channels to the signal terminals in a group manner based on the arrangement sequences of the signal channels reconfigured by the sequencers according to a control signal.

1. A routing circuit, configured to route a plurality of signal channels of a plurality of integrated circuits to a plurality of 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 between the sequencers and the signal terminals, 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 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 represents which signal terminal of the signal terminals is routed with the at least two signal channels.
