| # 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`. |
