25.4.3. System Trace Macrocell
The STM allows messages to be injected into the trace stream for delivery to the host debugger receiving the trace data. These messages can be sent through stimulus ports or the hardware EVENT interface. The STM allows these messages to be time stamped.
The STM supports an EVENT interface that can be used to post additional messages into a trace stream. In addition to the channels, 44 of the 64 EVENT signals are attached to the FPGA, which allows the FPGA to send additional messages using the STM.
