|
| RobustVerilog from Provartec |
Powerful and simple pre-processing tool to enhance Verilog.
Allows creation of generic designs and integrates automation into
the code. Free version limits the number of parameters but should
be good enough for a small to medium design.
|
| OutputLogic |

Scrambler Generator, and LFSR Counter, Generator.
|
| VITO (Verilog Implicit One-Hot) |

(IEEE 1364.1 compliant) commercial tools. VITO allows a designer to
express an algorithm with software-like statements, such as while,
and have them converted automatically into hardware.

|
| VBPP version 1.1 |
VBPP Verilog preprocessors. Note, this version is somewhat
old. Unfortunately, the new version (V1.2.0, next) fails
in the same way. Help is needed to bring these back to a working
state. |
| VBPP version 1.2 |
VBPP is a Verilog preprocess. The newest version, V 1.2.0, has had
its tool chain modernized and it can now be maintained with the GNU
autotools toolchain. To build, you can run ./configure with the
--prefix option. This program fails, unfortunately, and help is
needed to bring these back to a working state. For further
information or to help, contact the author: Martin d Anjou

tasks associated with using assertion libraries. Integral to Zazz is
the Front End consisting of an advanced incremental parser/elaborator

Front End is FREE after a 14-day trial of the total capability and
represents a major productivity tool even when assertions are not
being used.
