System and method for performing predictable signature analysis in the presence of multiple data streams

摘要

A computer system may include several integrated circuits and a routing circuit configured to route several data streams between the integrated circuits. The routing circuit includes several input ports, several output ports, and a signature analysis register coupled to one of the output ports. The signature analysis register is configured to collect data conveyed via the output port dependent upon whether the signature analysis register receives a tag identifying one of the plurality of data streams.
