Description

Hello, I have a question about RVFI (RISC-V Formal Interface).
If I just want to monitor RVFI signals or let RVFI signals output to other modules and without creating a text file, do I only need to `define RVFI in ibex_top.sv?
Is it unnecessary to use ibex_top_tracing.sv and ibex_tracer.sv?

## My Environment

**EDA tool and version:**

Vivado 2020.2

**Operating system:**

Ubuntu Linux 18.04

**Version of the Ibex source code:**

Research direction

Start with ibex_top.sv, ibex_top_tracing.sv, and ibex_tracer.sv, focusing on how RVFI signals are exposed and how tracing is used. Check the Ibex documentation and source at the relevant revision; done means a clear, revision-specific answer to the question for Vivado 2020.2.
