Frequently Asked Questions And Answers (Part 3): Products & Services

----------------------------------------------------------------------------
Preliminary Remarks

This is a monthly posting to comp.lang.vhdl containing information products
and services for VHDL (commercial and public domain) Please send additional
information directly to the editor:
http://www.velocityreviews.com/forums/(E-Mail Removed)-technik.uni-dortmund.de (Edwin Naroska)

Corrections and suggestions are appreciated. Thanks for all corrections.

There are three other regular postings: part 1 lists general information on
VHDL, part 2 lists books on VHDL, part 4 contains descriptions for a number
of terms and phrases used to define VHDL.

This product list is never up to date it seems - please help to update it.
This list is without any guarantee to be complete or correct. It is included
to enable contacts to vendors. It does not contain version, quality or price
information. (Please accept, that actually this information changes to fast
-too much work to keep such information up to date, but if there is a
volunteer willing to take this part.... If some kind of judgment is
included ('specialist' for example) it's not my personal opinion but a
remark from the vendor himself.

AMICAL
Description: AMICAL is an Interactive Architectural Synthesis Tool
based on VHDL developed at the system level synthesis group of
TIMA Laboratory at INPG, Grenoble, France. AMICAL starts with a
functional specification given in VHDL, it performs scheduling,
allocation and generates an architecture composed of a data-path
and a controller that may feed existing synthesis tools acting at
the logic and register transfer levels. AMICAL uses a powerful
scheduler and accepts a quite large VHDL subset (multiple waits,
nested loops, exits, procedures, functions...). The present
version produces a VHDL description that can be accepted by
Synopsys. AMICAL is organized as an interactive environment, it
provides several facilities for architecture analysis (statistics,
evaluation, links between the VHDL behaviour and the resulting
architecture...). The response time of AMICAL is short enough to
make it an interactive system. AMICAL is available free of Charge.
The present version has already been distributed to several
experimental centers. The present version runs on SPARC station
under SUNOS. Two versions of the graphical interface exists:
Openwindow, Suntools. The distribution include:
+ The AMICAL software.
+ A Tutorial
+ A user's Manual
+ A beginner Session
+ Synthesis exercices (6 Hours)

The distribution does not include the VHDL analyser. The present
version makes use of the VHDL Analyser of CLSI. A new version
based on LVS, the VHDL compiler from LEDA, will be available soon.
In case you have no the right VHDL analyser we added, the
distribution may include the compiled and scheduled version of all
the examples. Then you can use AMICAL with a fixed scheduling in
order to perform interactive synthesis. Of course this is useful
only for practicing with AMICAL or for Demonstration.

Electric
Description: Electric is a sophisticated electrical CAD system
that can handle many forms of circuit design, including Custom IC
layout (ASICs), Schematic drawing, Hardware description language
specifications, and Electro-mechanical hybrid layout. The VHDL
system can generate VHDL from a layout, and can compile structural
VHDL to netlists of various format. These netlists can then be
simulated with the built-in simulator, turned into layout with the
silicon compiler, or saved to disk for use in external simulators.

SAVANT
Description: The SAVANT project is an effort by University of
Cincinnati's Computer Architecture Design Lab to build an
extensible, object-oriented intermediate form (IIR) for the
hardware description language VHDL. The project produced a suite
of software to analyze VHDL, build the IIR, and output C++
suitable for execution with the TyVIS VHDL simulation kernel.
Further, the SAVANT analyzer has been designed to easily allow the
insertion of new back-ends into the tool. The software developed
under the SAVANT project is freely available. Users may modify,
distribute, and use the software contained in the SAVANT software
package under the terms of the "GNU LIBRARY GENERAL PUBLIC
LICENSE" version 2, June 1991.

verilog2vhdl : verilog2vhdl translates hierarchical Verilog HDL to
VHDL by using an HDL object kernel which converts the input to an
intermediate format and then back to the other HDL. It makes a full
translation of structural Verilog, and a partial translation of
behavioral Verilog. It supports all synthesizable Verilog as a subset
and uses a combination of IEEE and tool-specific VHDL packages to
perform the translation. VHDL that is created by verilog2vhdl is
functionally equivalent to input Verilog, and because of one-to-one
mapping of Verilog to VHDL, output VHDL is easy to
understand. Comments are preserved and placed after the line in the
translated code most closely matching the design intent. Test benches
can be translated also to verify that the output is correct. Output
VHDL is IEEE 1076-1993 compliant. Node-locked and floating licenses
are available for HP-UX, Solaris, SunOS and Windows NT platforms.

VHDL2verilog: VHDL2verilog translates hierarchical VHDL (full
structural, part RTL) to Verilog HDL. Verilog that is created by
VHDL2verilog is functionally equivalent to input VHDL. Comments are
preserved and placed after the line in the translated code most
closely matching the design intent. Test benches can be translated
also to verify that the output is correct. Both IEEE Std 1076-1993 or
IEEE Std 1076-1987 compliant VHDLs are processed by the system and
output Verilog is compatible with any Verilog-XL compatible
simulator. Node-locked and floating licenses are available for HP-UX,
Solaris, SunOS and Windows NT platforms.

VBIT®: JTAG Test Synthesis for ASIC and IC Designers. VBIT®, which was
the industry's first RT level JTAG Test Synthesis tool, is available
directly from the developer ASC. The product features automatic
boundary scan test logic insertion synthesis by a tool using
technology independent IEEE 1149.1 macros to read VHDL or Verilog
input and produce corresponding RT Level VHDL or Verilog output. A
Simulation Testbench is created in Verilog or VHDL to test the
Boundary Scan Circuitry. A BSDL output file is also created for easy
interface to Board Level ATE and creating test vectors. VBIT® also
supports custom mapping to vendor-specific JTAG cell libraries and
custom interfaces for internal scan, memory and logic BIST. VBIT®
frees engineers from learning the tedious details of IEEE 1149.1
standard and manually inserting boundary scan test logic into their
ASIC, IC or MCM designs in an error-free rapid way. VBIT® scan
implementation at the RT level promotes design re-use. Tools that
insert boundary scan test at the gate level are used too late in the
design cycle to be truly technology independent. Furthermore, by
implementing boundary scan before logic synthesis, the designers can
synthesize functional core logic and test logic concurrently and avoid
timing and area violations in the entire chip. This saves costly
design iterations. Node-locked and floating licenses are available for
HP-UX, Solaris, and SunOS platforms.

FRITS: FRITS is an object-oriented framework to interface with other
EDA tools and facilitate rapid development. FRITS translates Verilog
HDL or VHDL descriptions into an intermediate format (common object
format) and stores the data in an object kernel in memory. The object
kernel is accessible to the EDA tool developer via an Application
Program Interface (API). FRITS also provides an elegant mechanism for
easy extraction of the stored design data. All operations by FRITS are
fast.

VHDL Test Bench Tool

A tool to generate test benches that is both low-cost and unlike other
tools not constraining. Price 1/1/2001 is GBP80, $120 approx.

The tool generates fully functional VHDL but VHDL simple enough for
hand editing to be used to expand its functionality without limit.
The actual complex test vectors are stored in a separate file. Plus,
to make use of this flexibility, the test vectors can include
variables (e.g. integers, times, etc.) in addition to the UUT input
and output signals.

Complex signal relationships can easily be defined and again are not
constrained to a fixed set of constructs. This includes loops and
loops within loops. The loop counter can be used in the definition of
the signals. The test bench can be modular and individual modules
checked separately. A graphical plot of the test bench can be
displayed which is especially useful when looping is used.

A limited demo version is available and 30 day trial unlimited
licenses available by using the form.

Screenshots, worked example, downloads and license requests:
http://www.fullcircuit.com/TBtool.htm

The Test Bench tool program requires Excel 97+ so PC or MAC. No
knowledge of Excel is required.

In addition Full Circuit can provide bespoke VHDL IP, digital design,
analog design, and software. The web site also has some useful
freeware for PC (not VHDL related).

Overview
Qualis Design Corp of Beaverton, OR, offers high quality expert
consulting services in all aspects of using HDLs (both VHDL and
Verilog) including training, design environment, code management,
tooling, tool integration, behavioral modeling, test planning,
testbench infrastructure, testcase implementation, synthesis,
gate-level verification and more...

Training
Our classes differ from the traditional bottom-up, gate-to-behavioral
HDL training approach and reverses the flow starting with high-level
descriptions, testbench and top-down methodology. We feel this
high-level approach to training better fits an advanced design process
encouraging students to learn a methodology, and not just a
language. More than 70% of the time is spent on hands-on exercises
using the latest version of state-of-the-art VHDL, Verilog and
synthesis systems.

Semantic Designs provides software tools for
automating the analysis/modification/synthesis
of large scale specifications in many languages,
including VHDL and Verilog.

In particular, the DMS Reengineering Toolkit
(http://www.semdesigns.com/Products/DMS/DMSToolkit.html)
can parse arbitrary languages, automatically build compiler-like
Abstract Syntax Trees (ASTs), carry out analyses and surface-syntax
transforms on ASTs, and prettyprint the ASTs back to source language
form, for specifications of up to 2 million lines.

This tool is ideal for constructing custom analyzers and/or synthesizers.
Since DMS handle multiple languages (including C/C++, Java, Ada, ...),
and can have custom languages easily added as well,
it would be ideally suited as the foundation for CoDesign
applications.

Product Name: Visual HDL
Visual HDL[TM] integrates four graphical languages, a textual language,
a simulator and debugger, and code generators for VHDL and Verilog. It
uses a state-of-the-art, object-oriented user interface, featuring a
graphical design browser.
Visual HDL includes intelligent editors for input of block diagrams,
state diagrams, flowcharts, and truth tables, besides VHDL text. This
comprehensive set of languages helps you to work at any level of
abstraction, and to mix levels of abstraction.
With Visual HDL you can create a high level description of your
design and validate it by execution. An event-driven, interactive
simulator works in tandem with a source-level debugger for rapid
analysis of the system. While the simulator runs, you can set
breakpoints, modify existing signals and variables, single-step through
multiple execution threads, and trace various activities. Visual
feedback appears on your source descriptions, in the windows of their
editors, for easy tracing.
Following design verification, Visual HDL generates VHDL or Verilog
code customized for the commercial synthesis tool you specify.
Visual HDL is available for UNIX and for Microsoft Windows.

VHDL Test Bench and Stimulus Generators

SynaptiCAD develops stimulus generators and test bench generators
for VHDL. SynaptiCAD's premier product TestBencher Pro, is a
self-testing multi-diagram test bench generator. TestBencher Pro can
detect glitches, bad logic levels, and violations of setup and hold
times in simulation output. Users draw inputs to a simulation and
specify expected simulation outputs using graphical constructs called
samples. TestBencher Pro generates VHDL test benches with extra code
which verifies that graphically-specified conditions are met by a
simulator's output. Users can concatenate timing diagrams together to
mimic a series of read/write bus cycles. TestBencher Pro also has
looping and conditional constructs that enable simulation results to
control what stimulus is applied next.

SynaptiCAD also offers WaveFormer Pro, a timing diagram editor and
VHDL stimulus generator. Users draw a timing diagram that represents the
input to a simulation. Then the user exports the timing data as a VHDL
process that contains either transport or wait statements. WaveFormer
Pro supports all VHDL data types. Even user defined types like "type
MyColor is (RED, BLUE, GREEN)" can be exported with both type and state
information. TestBencher Pro and WaveFormer Pro are offer three
different ways to enter signal waveforms: (1) a graphical environment
for drawing, (2) text based temporal equations, and (3) boolean
equations of other signals. Other simulator formats are also supported
including Verilog, SPICE, Viewlogic, Orcad, Mentor QuickSim, HP Logic
Analyzers, HP Pattern Generators, and more, so timing diagrams can be
reused at different times during design process.

Vanilla VHDL is a complete implementation of the 1987 IEEE standard,
including configurations. Like the old MCC system, it is completely
text-based, with a gdb-like command set for its debugger/simulator.
Unlike MCC, it does not translate to C, but instead uses an interpreted
engine, since this simplifies debugger implementation and enhances
portability.
To fund further development of the tools, they are now commercially
available on the PC. A 386 or better is required. An introductory
price is in effect until July 30, 1995.

for the authoring, integration and delivery of system-on-chip
(SOC) designs. DesignBook includes (besides other tools) a state
machine designer, a truth table designer, a flowchart designer and
imports VHDL and Verilog designs.

6. C/C++ to VHDL Translators

This section lists commercial tools which support HDL code generation from C
and/or C++ source. Any additions/updates/corrections are appreciated!

o JRS Research Laboratories Inc.
+ Website: http://www.jrs.com/
+ Product: LegaC
+ Versions: ?
LegaC translates an input program coded in ANSI C into an
equivalent behavioral VHDL source-code program. The output program
is logically equivalent to the input program in the sense that a
VHDL compilation and simulation of the translated program will
produce the same results as a compilation and execution of the
original C source program.
o Forte Design Systems
+ Website: http://www.forteds.com/
+ Product: Cynthesizer
+ Versions: ?
Cynthesizer is a tool that takes a Cynlib design (Cynlib is a set
of C++ classes that provide a vocabulary for hardware modeling in
C++) and produces an equivalent representation in Verilog or VHDL
while maintaining the bit- and cycle-accuracy of the design.
Higher-level data structures, such as C++ classes, are
automatically transformed into functionally equivalent Verilog or
VHDL. Other object-oriented features of C++, such as inheritance,
are automatically resolved in the resulting Verilog or VHDL.
o Frontier Design
+ Website: http://www.frontierd.com/
+ Product: A|RT Builder
+ Versions: Win98, WinNT, Sun Solaris, HP HPUX, Linux
With A|RT Builder a designer can automatically convert a C
description into an RTL description, expressed either in VHDL or
Verilog HDL. The resulting HDL code can be used directly in a
logic synthesis flow, or can be further optimized using behavioral
synthesis tools.
