Open Verification Foundation
Links to Building a Complete
Open Environment
There is alot of overwhelming open source material
out there. We recomend focusing on this proven core set of material provided
below as the basis to building an environment
| Core (Must Have) Open Source Verification Software: | |
| Vendor | Description |
| verilator | Verilog RTL to C translator. Write your RTL in Verilog. Write your test environment in SystemC, then convert your Verilog RTL to SystemC and run the whole thing on the OSCI simulator. Pay only for the cost of cheap Linux machines. This is the solution for any startup on a budget! Also check the linting and System Perl tools. This is also your open source alternative to tools provided by Carbon Design or Tni-Valiosys or Others . |
| Icarus Verilog | Icarus Verilog is a FREE Verilog simulation and synthesis tool with VPI!. Less performance than the Verilator approach above, but much easier to debug. Icarus Verilog is a Verilog simulation and synthesis tool. It operates as a compiler, compiling source code written in Verilog (IEEE-1364) into some target format. For batch simulation, the compiler can generate an intermediate form called vvp assembly. This intermediate form is executed by the 'vvp' command. For synthesis, the compiler generates netlists in the desired format. The compiler proper is intended to parse and elaborate design descriptions written to the IEEE standard IEEE Std 1364-2001. |
| Cver | Cver is a full featured IEEE
P1364 Verilog simulator. Features are:
|
| Verilogger | This a simulator plus automatic test bench generation tool, Supports upto 500 Line of Verilog code. |
| VBS | copy-lefted Verilog simulator called "vbs", written by Jimen Ching and Lay Hoon Tho. Currently this simulator is not actively developed. |
| Oroboro/APVM | Oroboro is an open source Hardware Verification Language based on Python. To be more precise, Oroboro is a runtime system comprising a low-level Verilog VPI to Python interface, and a collection of Python class libraries. The language is simply Python. The resulting toolkit provides the basis for the creation of class libraries providing many of the features of full-fledged "Verification" languages. This tool is very easy to link into any Verilog simulator and if one chooses not to consider it for use as a verification tool, it certainly should be considered as an easy implementation scheme for things like embedded hash tables. I'm still exploring this tool, but it looks exciting. |
| parallel | http://richardbradley.org/ Forget LSF, netbatch, grid, use this "parallel" tpp; and submit batch jobs for free! |
| (SystemC_with_SCV_2.01) or (SystemC_with_SCV_2.1beta11) | Use my implementation of Doxygen to document the SystemC libraries. Or download Doxygen (see below) and build the 120MB database yourself. This is a must have to explore the true functionality in the SystemC and SCV libraries. Follow the link, then BOOKMARK it and and use it anywhere. |
| Stu Sutherland Home Page | I find the PLI examples provided on this page to be most rewarding |
| SystemC Home Page | Documention and core simulator and SCV library |
| Assertions in SystemC | from Tom Peng of Axiowave - originally from www.geocities.com/qxp0069. See install notes |
| Doxygen | Must have documentation generator. Spend 10 minutes building up your "Doxyfile" then browse through your files and classes in a simple to use hyperlinked HTML format! For the best results, Doxygen can make use of a tool called Dot, which is supplied as part of the graphics visualization library Graphviz. What this means is that you get prettier pictures if you have Graphviz. Graphviz is available here |
| Secondary (Nice to Have) Open Source Verification Software: | |
| Linux to NTFS conversions | While not EDA tools, this helpful tool allows one to see windows 2000 (NTFS) disk partitions from linux. |
| NTFS to Linux conversions | While not EDA tools, this helpful tool allows one to see linux partitions from windows 2000 (NTFS). |
| VNC | Forget netmeeting, citrix, exceed, ... This is a fast, and stable way to share your desktop with someone across the world. |
| cygwyn | Cygwin is a Linux-like environment for Windows |
| cpan | Comprehensive Perl Archive Network. Don't discount what perl can do for your environment. Expecially with todays object oriented Perl techniques |
| mingw | MinGW ("Minimalistic GNU for Windows") refers to a set of runtime headers, used in building a compiler system based on the GNU GCC and binutils projects. It compiles and links code to be run on Win32 platforms... providing C, C++ and Fortran compilers plus other related tools. |
| Arithmetic Module Generator | The arithmetic module generator will generate add, subtract, multiply, squarer and wallace tree modules. Many, many, option such as data bus width and pipeline stages. It will generate either Verilog or VHDL code. |
| GPL Cver | free, open-source Verilog HDL simulator. Supports the full 1995 P1364 Verilog standard and some of the 2001 P1364 features, including all three PLI interfaces (tf_, acc_ and vpi_). System C. |
| TopGen | (3kB) from www.asics.ws TopGen is a perl script that takes one or more Verilog Modules and connects them together in a newly generated top level module. It can take a top level module prototype as an optional input as well. Further it supports aliases where signals with different names in the modules are connected together on the top level using a common signal name. Automatic width specification is also performed. The resulting top level will most likely still require manual editing, but 99% of the tedious copy, paste and typing work is eliminated. |
| Verilog2C++ | translates a C++ class of a Verilog design using a cycle-accurate representation of each nets and registers. Verilog2C++ is about 10 times faster than other commercial simulators, but has only simple functions. |
| mpatrol | Very Cool Memory Leak Detection tool |
| Bison, Flex | Context free to C grammer parsers: |
| Gtk | GUI creation tool |

| v2html | Verilog to HTML converter, browse though your design in hyperlinked HTML. |
| Spark | Ok, we don't promote C-based design, Just Verification, but I recognize some value in this C to RTL synthesis tool. Actually I recognize alot of value for those that want to write Palladium friendly testbenches. |
| Open Collector | I can't begin to describe the wealth of tools available on this site. I do not repeat most of them here because most do not specifically address the problems that I am trying to solve. |
| gEDA | The gEDA project is working on producing a full GPL'd suite of Electronic Design Automation tools. Forget Verisity's Verification Process Automation (VPA) Solutions, these guys offer design and verification management tools that are kind of slick. Also some waveform tools and back end stuff. |
| www.verificationlib.org | This website appears to have died. 12/10/04. |
| gnu | Not recommending anything specific, just a link |
| Thinking in CPP | CPP documentation. Put this in a directory with SCV docs and the SystemC LRM. Then use acrobat 6.0 and you can do searches across the entire directory. You can easily resolve an issue across the 3 documents. |
| opensparc | Sun is opening up the entire full-chip RTL of it's latest commercially released SPARC microprocessor under an OSI approved open source license! ( Of course, some export control and 3rd party IP will be removed if they are not allowed, but the intent is to take the RTL that went to silicon on the Niagara chip and put it out there for the open source hardware community. Thanks to Aman Joshi |
