 The Scala FIRRTL Compiler and the MLIR FIRRTL Compiler
 ------------------------------------------------------
-In Chipyard, two FIRRTL compilers work together to compile Chisel into Verilog. The Scala FIRRTL compiler(SFC) and the MLIR FIRRTL compiler(MFC).

By setting the ``ENABLE_CUSTOM_FIRRTL_PASS`` env variable to a non-zero value, we can make the SFC compile Chisel into LowFIRRTL so that our custom FIRRTL passes are applied.

 Where to add transforms
 -----------------------
 
-In Chipyard, the FIRRTL compiler is called multiple times to create a "Top" file that contains the DUT and a "Harness" file containing the test harness, which instantiates the DUT.
-The "Harness" file does not contain the DUT's module definition or any of its submodules.
+In Chipyard, the FIRRTL compiler is called multiple times to create a "Top" file that contains the DUT and a "Model" file containing the test harness, which instantiates the DUT.
+The "Model" file does not contain the DUT's module definition or any of its submodules.
 This is done by the ``tapeout`` SBT project (located in ``tools/barstools/tapeout``) which calls ``GenerateModelStageMain`` (a function that wraps the multiple FIRRTL compiler calls and extra transforms).

 `FIRRTL <https://github.com/freechipsproject/firrtl>`__ is an intermediate representation of your circuit.
 It is emitted by the Chisel compiler and is used to translate Chisel source files into another representation such as Verilog.
-Without going into too much detail, FIRRTL is consumed by a FIRRTL compiler (another Scala program) which passes the circuit through a series of circuit-level transformations.
+Without going into too much detail, FIRRTL is consumed by FIRRTL compilers which passes the circuit through a series of circuit-level transformations.
 An example of a FIRRTL pass (transformation) is one that optimizes out unused signals.
 Once the transformations are done, a Verilog file is emitted and the build process is done.
