Similar to #10956 flex needs to be a link-dependency for verilator in order for FlexLexer.h to be found during install.

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."""
