+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.

+
+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
