Historical Origins
|
|
==================
|
|
|
|
Verilator was conceived in 1994 by Paul Wasson at the Core Logic Group at
|
|
Digital Equipment Corporation. The Verilog code that was converted to C
|
|
was then merged with a C based CPU model of the Alpha processor and
|
|
simulated in a C based environment called CCLI.
|
|
|
|
In 1995 Verilator started being used also for Multimedia and Network
|
|
Processor development inside Digital. Duane Galbi took over active
|
|
development of Verilator, and added several performance enhancements. CCLI
|
|
was still being used as the shell.
|
|
|
|
In 1998, through the efforts of existing DECies, mainly Duane Galbi,
|
|
Digital graciously agreed to release the source code. (Subject to the code
|
|
not being resold, which is compatible with the GNU Public License.)
|
|
|
|
In 2001, Wilson Snyder took the kit, and added a SystemC mode, and called
|
|
it Verilator2. This was the first packaged public release.
|
|
|
|
In 2002, Wilson Snyder created Verilator 3.000 by rewriting Verilator from
|
|
scratch in C++. This added many optimizations, yielding about a 2-5x
|
|
performance gain.
|
|
|
|
In 2009, major SystemVerilog and DPI language support was added.
|
|
|
|
In 2018, Verilator 4.000 was released with multithreaded support.
|
|
|
|
In 2019, Verilator joined the `CHIPS Alliance
|
|
<https://chipsalliance.org>`_.
|
|
|
|
Currently, various language features and performance enhancements are added
|
|
as the need arises. Verilator is now about 3x faster than in 2002, and is
|
|
faster than most (if not every) other simulator.
