15.2.3 Integrated tool solutions

CoreSight™ designs can contain shared debug resources which need to be managed and used from multiple tools. For example, the system might be able to generate trace from several trace sources, such as ARM® cores + DSP. In legacy designs, the trace paths would be independent and each debug tool would have its own connection to the respective sub-system. In a typical CoreSight system, the trace data is merged by a Funnel component and delivered to a single trace storage device though a single interface. The trace data is then uploaded and de-multiplexed. The trace data might need to be delivered to several different debug tools, such as ARM DS-5 and DSP Debug Tool.

DTSL addresses the tool integration problem that this situation raises.
