-**verilator (Verilator wrapper)**
+**Verilator**
   Verilator is an open source Verilog simulator.
   The ``verilator`` directory provides wrappers which construct Verilator-based simulators from relevant generated RTL, allowing for execution of test RISC-V programs on the simulator (including vcd waveform files).
   See :ref:`Verilator (Open-Source)` for more information.
 
-**vcs (VCS wrapper)**
+**VCS**
   VCS is a proprietary Verilog simulator.
   Assuming the user has valid VCS licenses and installations, the ``vcs`` directory provides wrappers which construct VCS-based simulators from relevant generated RTL, allowing for execution of test RISC-V programs on the simulator (including vcd/vpd waveform files).
   See :ref:`Synopsys VCS (License Required)` for more information.

+**FPGA Prototyping**
+  FPGA prototyping is supported in Chipyard using SiFive's ``fpga-shells``.
+  Some examples of FPGA's supported are Arty and VCU118.
+  For more accurate and deterministic simulation results, please consider using the :ref:`FireSim` platform.
