Abstract: Detecting and recovering from timeouts in scalable mesh circuits in processor-based devices is disclosed herein. In some exemplary aspects, a processor-based device provides an integrated circuit (IC) that includes an interconnect comprising a scalable mesh network communicatively coupled to a plurality of agents via a respective plurality of bridge devices. The plurality of agents includes a source agent and a target agent that communicate with a source bridge device and a target bridge device, respectively. The target bridge device receives a transaction directed to the target agent from the source agent via the interconnect. Upon receiving the transaction, the target bridge device initiates a timeout counter. If no response to the transaction received by the target bridge device from the target agent by the time the timeout counter expires, the target bridge device transmits to the source bridge device an indication that no response to the transaction was received.
