2.2.1.7. Enable AMBA* Trace Bus (ATB)

The AMBA* Trace Bus on the FPGA boundary allow ATB compatible sources to be enabled as soft IP on fabric to transport messages generated on the fabric to the CoreSight trace infrastructure.

Turning on the Enable AMBA* Trace Bus option enables the f2atb_trace_bus conduit, which is comprised of the following signals:
