Abstract

Systems and methods for routing packets around dead dies in an array are disclosed. In some embodiments, a method for routing a packet in a die array that include a dead die can include routing a packet from a first die to a second die by way a first channel of a plurality of first channels and routing the packet from the second die to a third die by way of a second channel of a plurality of second channels based on one or more routing rules. The one or more routing rules can allow the first channel to route the packet to a subset of the plurality of second channels that includes the second channel. The second channel can be orthogonal to the first channel such that routing the packet from the first die to the third die involves a turn. The method can route the packet around the dead die.

Dependent claims

A method of dead die bypass routing, the method comprising:

routing a packet from a source die to an intermediate die via a first route, the first route comprising turning the packet from a first channel of a plurality of first channels to a second channel of the plurality of second channels based on one or more routing rules, the one or more routing rules allowing the first channel to route the packet to a subset of the plurality of second channels that includes the second channel, and the first channel being orthogonal to the second channel;
and
routing the packet from the intermediate die to a destination die via a second route, the second route comprising turning the packet from the second channel to a third channel that is orthogonal to the second channel,
wherein a system on a wafer includes a die array comprising the source die, the intermediate die, the destination die, and at least one dead die, and
wherein the first route and the second route bypass the at least one dead die.
