11.4.6. Trace Port Interface Unit

The TPIU is a bridge between on-chip trace sources and an off-chip trace port. The TPIU receives trace data from the Trace Bus Replicator (Replicator) and drives the trace data to a trace port analyzer.

The trace output from the TPIU is software programmable and can be set to either 8 or 32 bits wide. The trace output is routed to an 8‑bit HPS I/O interface and a 32‑bit interface to the FPGA fabric. The trace data sent to the FPGA fabric can be transported off-chip using available serializer/deserializer (SERDES) resources in the FPGA.
