Debugging BOOM
|
|
======================
|
|
|
|
In addition to the default debugging techniques specified in :ref:`Debugging RTL`,
|
|
single-core BOOM designs can utilize the Dromajo co-simulator (see :ref:`Dromajo`)
|
|
to verify functionality.
|
|
|
|
.. warning:: Dromajo currently only works in single-core BOOM systems without accelerators.
|
|
|
|
.. warning:: Dromajo currently only works in VCS simulation and FireSim.
|
|
|
|
Setting up Dromajo Co-simulation
|
|
--------------------------------------
|
|
|
|
Dromajo co-simulation is setup to work when two config fragments are added to a BOOM config.
|
|
First, a ``chipyard.config.WithTraceIO`` config fragment must be added so that BOOM's traceport is enabled.
|
|
Second, a ``chipyard.iobinders.WithSimDromajoBridge`` config fragment must be added to
|
|
connect the Dromajo co-simulator to the traceport.
|
|
Once both config fragments are added Dromajo should be enabled.
|
|
|
|
To build/run Dromajo with a BOOM design, run your configuration the following make commands:
|
|
|
|
.. code-block:: shell
|
|
|
|
# build the default Dromajo BOOM config without waveform dumps
|
|
# replace "DromajoBoomConfig" with your particular config
|
|
make CONFIG=DromajoBoomConfig ENABLE_DROMAJO=1
|
|
|
|
# run a simulation with Dromajo
|
|
make CONFIG=DromajoBoomConfig ENABLE_DROMAJO=1 BINARY=<YOUR-BIN> run-binary
