+class Verilator(AutotoolsPackage):
+    """Verilator is the fastest free Verilog HDL simulator.
+
+    It compiles synthesizable Verilog (not test-bench code!), plus some PSL,
+    SystemVerilog and Synthesis assertions into C++ or SystemC code. It is
+    designed for large projects where fast simulation performance is of primary
+    concern, and is especially well suited to generate executable models of
+    CPUs for embedded software design teams.
+
+    Please do not download this program if you are expecting a full featured
+    replacement for NC-Verilog, VCS or another commercial Verilog simulator
+    or Verilog compiler for a little project! (Try Icarus instead.) However, if
+    you are looking for a path to migrate synthesizable Verilog to C++ or
+    SystemC, and writing just a touch of C code and Makefiles doesn't scare you
+    off, this is the free Verilog compiler for you.
+
+    Verilator supports the synthesis subset of Verilog, plus initial
+    statements, proper blocking/non-blocking assignments, functions, tasks,
+    multi-dimensional arrays, and signed numbers. It also supports very simple
+    forms of SystemVerilog assertions and coverage analysis. Verilator supports
+    the more important Verilog 2005 constructs, and some SystemVerilog
+    features, with additional constructs being added as users request them.
+
+    Verilator has been used to simulate many very large multi-million gate
+    designs with thousands of modules."""
