Surf these sites: CynApps, Inc: Cynthesis Applications -- Cynlib: open source C++ hardware design class library and simulator. Free Model Foundry: FMF -- (formerly The Free Model Foundation) Dedicated to advancing standard modeling practices within the electrical engineering community. We especially support use of VHDL, Verilog, and IBIS modeling languages. Current focus: providing functional simulation models (with timing) of off-the-shelf digital components in VHDL and Verilog. Free-IP Project -- Goal: make quality Intellectual Property available to anyone. Includes high quality large cores in synthesizeable VHDL. Freecore.com -- The Altera Freecore Library for Altera CPLD devices. VHDL, Verilog, design tools, architectures. Not supported any more. Hamburg VHDL Archive -- Goal: provide a collection of free (public-domain & shareware) VHDL documentation, models, tools. Links: Open Hardware -- Small page: links to pages and projects related to open hardware and free EDA systems. Microcontroller: VHDL: PIC 16C5X -- One stable version, and another one under development. News: Deja.com: Free SPARC VHDL model available -- Initial announcement of the GPL''d LEON Sparc architecture. Open Design Circuits -- Open Design Circuits: what does it mean? Open Hardware Certification Program: OpenHardware.org -- Self-certification program for hardware makers to make a set of promises about availability of documentation for programming device-driver interfaces of specific hardware devices and OSs. Guarantees that anyone who wants to write a device driver for one can get the information needed to do so. Does not guarantee availability. OpenCollector Database -- Site has a searchable index of many designs, tools, manufacturers, dependencies. If it exists, it''s listed here.. OpenCore Project -- Project to build a collection of all kinds of free hardware cores that can be used by companies to speed their development. OpenIP Organization & OpenCore Project -- OpenIP: define how hardware and IP cores can be made free and how to design such free HW circuits; define license and design methodologies for such projects. OpenCore: hardware project to build a collection of all kinds of free cores for use by companies to speed up hardware-development. Paper: Open Source Hardware Page -- Industry analysis paper for a college course proposing a business to apply the Open Source model to hardware. Press: Linux Today: Richard Stallman: On Free Hardware -- by R. Stallman: thoughts on Free Hardware as of June 1999.

Processor: CMOSexod.com -- For advanced hobbyists: share free microprocessor and DSP IP cores written in Verilog or VHDL. Processor: E-Risc -- Project to design and implement scaleable RISC microprocessor for embedded applications. All architecture and source code to be released under GNU General Public License, or a slightly modified version that includes hardware, not only software. Processor: F-CPU Project -- Freedom CPU project for a free 64 bit CPU and related systems. Still in design mode, no HDL. Processor: LEON-1 -- A functional GPL''d VHDL Sparc Processor. Works on Altera, Temic MG2, Mietec, Xilinx. Processor: MMIX: a RISC computer for the third millennium -- Donald E. Knuth''s new 64-bit processor for the new volumes of his landmark series: ''The Art of Computer Programming''. But might MMIX become more than only a book example. Processor: MMIXmasters.org -- Site for volunteers (MMIXmasters) who are converting all programs in TAOCP, Vol 1-3 from Knuth''s old language MIX to his new language MMIX. Processor: STM -- 32-bit, 2-way superscalar RISC processor, designed in a HDL. Get the source from here. This one is actually working. Project: OpenCORES.org -- OpenCORES.org endorses development of open source, free IP cores. They are building their own Microprocessors and supplemental systems. RASSP -- This educational material is now available to Colleges and Universities for use as instructional tools for non-commercial educational purposes. College and University educators may request these RASSP developed modules through the RASSP Information Server. VHDL. VHDL Database of Phase/MACAO -- It is our aim to provide free access to VHDL source code and related material. Therefore, we have installed a database that you may access via the WWW.
