Abstract: The present disclosure describes a debugging system that includes an aggregation network and a distribution network. The aggregation network can include leaf nodes and a first root node coupled to the leaf nodes. The leaf nodes can collect error information about error events in a functional circuits and transmit the error information to the first root node. The distribution network can include a second root node coupled to the first root node. The second root node can receive the error information from the first root node and distribute the error information to responding functional circuits to perform an action based on the error information.

Abstract: The present disclosure describes a device including an initiator, a target, a communication bus coupling the initiator to the target over a channel, a functional circuit, and an error logger circuit. The functional circuit is coupled to the channel and can perform a function associated with a transaction request from the initiator to the target. The functional circuit can include an error detection circuit to detect an error associated with the function performed by the functional circuit and to generate an error indicator signal to indicate that the error has been detected. The error logger circuit can be coupled to the functional circuit, in which the error logger circuit is configured to receive the error indicator signal from the error detection circuit and store information about the error.
