Example: Ibex with enabled instruction tracing for simulation

Overview

This examples shows the usage of the module ibex_core_tracing which forwards all port signals to the ibex_core and a subset of signals to ibex_tracer. The tracer will create a file with a stream of executed instructions.

Prerequisites

For this example, modelsim must be available and the following environment variable must point to the path of installation:

export MODEL_TECH=/path/to/modelsim/bin

Usage

Run the following command in the top level directory.

fusesoc --cores-root=. run --target=sim lowrisc:ibex:top_tracing_sim

The trace output can be found in build/lowrisc_ibex_top_tracing_sim_0.1/sim-modelsim/trace_core_00_0.log.
