By default, Chipyard uses the Tethered Serial Interface (TSI) to communicate with the DUT.
TSI protocol is an implementation of HTIF that is used to send commands to the RISC-V DUT.
These TSI commands are simple R/W commands that are able to access the DUT's memory space.
During simulation, the host sends TSI commands to a simulation stub in the test harness called ``SimSerial``
(C++ class) that resides in a ``SimSerial`` Verilog module (both are located in the ``generators/testchipip``

This ``SimTSI`` Verilog module then sends the TSI command recieved by the simulation stub
to an adapter that converts the TSI command into a TileLink request.
This conversion is done by the ``SerialAdapter`` module (located in the ``generators/testchipip`` project).
This conversion is done by the ``TSIToTileLink`` module (located in the ``generators/testchipip`` project).
After the transaction is converted to TileLink, the ``TLSerdesser`` (located in ``generators/testchipip``) serializes the
transaction and sends it to the chip (this ``TLSerdesser`` is sometimes also referred to as a digital serial-link or SerDes).
Once the serialized transaction is received on the chip, it is deserialized and masters a TileLink bus on the chip

sends the DMI command recieved by the simulation stub into the DUT which then converts the DMI

When the DTM receives the program to load, it starts to write the binary byte-wise into memory.

Assuming this example test chip is taped out and now ready to be tested, we can communicate with the chip using this serial-link.
For example, a common test setup used at Berkeley to evaluate Chipyard-based test-chips includes an FPGA running a RISC-V soft-core that is able to speak to the DUT (over an FMC).
This RISC-V soft-core would serve as the host of the test that will run on the DUT.
This is done by the RISC-V soft-core running FESVR, sending TSI commands to a ``SerialAdapter`` / ``TLSerdesser`` programmed on the FPGA.
This is done by the RISC-V soft-core running FESVR, sending TSI commands to a ``TSIToTileLink`` / ``TLSerdesser`` programmed on the FPGA.
Once the commands are converted to serialized TileLink, then they can be sent over some medium to the DUT
(like an FMC cable or a set of wires connecting FPGA outputs to the DUT board).
Similar to simulation, if the chip requests offchip memory, it can then send the transaction back over the serial-link.

===============================
A simple way to copy over a source file to the build directory to be used for a simulation compile or VLSI flow is to use the ``addResource`` function given by FIRRTL.
An example of its use can be seen in `generators/testchipip/src/main/scala/SerialAdapter.scala <https://github.com/ucb-bar/testchipip/blob/master/src/main/scala/SerialAdapter.scala>`_.
An example of its use can be seen in `generators/testchipip/src/main/scala/SimTSI.scala <https://github.com/ucb-bar/testchipip/blob/master/src/main/scala/SimTSI.scala>`_.
Here is the example inlined:
.. code-block:: scala
class SimSerial(w: Int) extends BlackBox with HasBlackBoxResource {
class SimTSI extends BlackBox with HasBlackBoxResource {
val io = IO(new Bundle {
val clock = Input(Clock())
val reset = Input(Bool())
val serial = Flipped(new SerialIO(w))
val tsi = Flipped(new TSIIO)
val exit = Output(Bool())
})
addResource("/testchipip/vsrc/SimSerial.v")
addResource("/testchipip/csrc/SimSerial.cc")
addResource("/testchipip/vsrc/SimTSI.v")
addResource("/testchipip/csrc/SimTSI.cc")
}
In this example, the ``SimSerial`` files will be copied from a specific folder (in this case the ``path/to/testchipip/src/main/resources/testchipip/...``) to the build folder.
In this example, the ``SimTSI`` files will be copied from a specific folder (in this case the ``path/to/testchipip/src/main/resources/testchipip/...``) to the build folder.
The ``addResource`` path retrieves resources from the ``src/main/resources`` directory.
So to get an item at ``src/main/resources/fileA.v`` you can use ``addResource("/fileA.v")``.
However, one caveat of this approach is that to retrieve the file during the FIRRTL compile, you must have that project in the FIRRTL compiler's classpath.
