DESCRIPTION:Tracing FPGAs in heterogeneous systems remains a significant ch
 allenge. Vendor-provided hardware tracing tools often have limited trace d
 urations\, which restrict visibility into complex and long-running issues.
  When combined with the inherent complexity of heterogeneous platforms\, t
 his limitation makes debugging and performance analysis especially difficu
 lt. Tracing software and hardware separately further complicates matters\,
  as aligning software events with FPGA logic becomes a tedious and error-p
 rone task\, leaving designers without a clear understanding of system-wide
  behaviors. This presentation introduces a solution that bridges this gap:
  a combined tracing approach that integrates FPGA and software event trace
 s into a unified view. Our work comprises an FPGA core capable of tracing 
 AXI transactions\, signals\, and state machines\, along with a software co
 mponent that collects and processes the trace data. The FPGA core timestam
 ps events and transmits them over DMA to software\, where they are stored 
 with synchronized time markers for post-processing. The result is a cohesi
 ve\, time-aligned trace that can be analyzed in conjunction with software 
 traces\, offering designers deeper insight into system interactions and ma
 king root cause analysis more accessible.
