Background In the field of chip design verification, when a plurality of channels share a set of socket driving requests, the prior art serializes all channels, i.e. the channels queue for interface usage rights according to a preset sequence. When the channel occupying the interface at present cannot drive the request due to insufficient credit, the channel still continuously occupies the interface, and even if the exclusive credit pool of other channels has enough credit, other channels can not drive the request due to the occupied interface, and can only wait for the previous channel to release the interface. Obviously, the prior art causes a strong coupling relation between channels, so that bandwidth resources of an interface are seriously wasted.
