Abstract
Systems and methods are disclosed for distributing and replaying trigger packets via a variable latency bus interconnect in a trace system. An embodiment of such a method comprises generating a plurality of trigger packets from a plurality of trigger sources on a system on chip. Each trigger packet defines a corresponding event and a corresponding system-generated timestamp. The plurality of trigger packets are distributed from the corresponding trigger sources to a centralized logic analyzer via a variable latency bus interconnect. The received triggered packets are re-ordered according to the corresponding system-generated timestamps into an order in which the corresponding events occurred. The received trigger packets are replayed in the order in which the corresponding events occurred.
