Abstract:
1. A circuit for monitoring protocol-defined information packets including both data and packet routing information, wherein the protocol-defined information packets are either response packets or request packets and are put onto an interconnect by one or more modules for analysis including debugging of the circuit, wherein each module has a unique identification on the interconnect and wherein the routing information identifies at least one of the modules associated with the data, said circuit comprising: circuitry for determining whether information in a protocol-defined information packet matches one or more conditions and wherein the determining circuitry identifies the source and type of the matched protocol-defined information packet; circuitry responsive to determining that the information in the protocol-defined information packet matches one or more conditions for capturing a portion of the matched protocol-defined information packet circuitry for preventing the source of the matched protocol-defined information packet from putting further protocol-defined information packets onto said interconnect; and transferring the portion of the matched protocol-defined information packet to a debug module for analysis.
