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.
Dromajo co-simulation is setup to work when three config fragments are added to a BOOM config.
* A ``chipyard.config.WithTraceIO`` config fragment must be added so that BOOM's traceport is enabled.
* A ``chipyard.iobinders.WithTraceIOPunchthrough`` config fragment must be added to add the ``TraceIO`` to the ``ChipTop``
* A ``chipyard.harness.WithSimDromajoBridge`` config fragment must be added to instantiate a Dromajo cosimulator in the ``TestHarness`` and connect it to the ``ChipTop``'s ``TraceIO``
Once all config fragments are added Dromajo should be enabled.
To build/run Dromajo with a BOOM design, run your configuration the following make commands:
