Split-transaction bus intelligent logic analysis tool

A protocol analyzer comprising:

• a bus synchronizer configured to receive link traffic from a split-transaction link and frame the link traffic into a plurality of framed packets, the plurality of framed packets including a plurality of request packets and a plurality of response packets;
• a decoder configured to receive the plurality of framed packets and decode the plurality of framed packets into decoded packets, wherein at least one of the decoded packets includes information from a request packet and information from a corresponding response packet;
• and
• a logic analysis function configured to receive the decoded packets and initiate a trigger action on receipt of one of the decoded packets;
• and
• wherein the decoder is further configured to replace a tag in the corresponding response packet with an address from the request packet to form the at least one of the decoded packets.

A method of analyzing a bus comprising:

• receiving and framing link traffic from a split-transaction link into a plurality of framed packets, the plurality of framed packets including a plurality of request packets and a plurality of response packets;
• decoding the plurality of framed packets into decoded packets, wherein at least one of the decoded packets includes information from a request packet and information from a corresponding response packet, wherein the decoding further comprises replacing a tag in the corresponding response packet with an address from the request packet to form the at least one of the decoded packets;
• and
• analyzing the decoded packets and initiating a trigger action on receipt of one of the decoded packets.
