Opencores.org - Endorses, facilitates developing open source, free IP cores: building their own processors and supplemental systems. Developing chip designs should be done in an open environment, where cooperation and communication between designers and users yields better designs for all. IP core sources should be free to everyone, anytime, and all are welcome to participate. Repository of IP synthesizable blocks and supplemental prototype boards.
Open Source Hardware Page - Industry analysis paper for a college course proposing a business to apply the Open Source model to hardware.
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.
Freecore.com - The Altera Freecore Library for Altera CPLD devices. VHDL, Verilog, design tools, architectures. Not supported any more.
Free-IP Project - Goal: make quality Intellectual Property available to anyone. Includes high quality large cores in synthesizeable VHDL.
Hamburg VHDL Archive - Goal: provide a collection of free (public-domain & shareware) VHDL documentation, models, tools.
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.
Microcontroller: VHDL: PIC 16C5X - One stable version, and another one under development.
Press: Linux Today: Richard Stallman: On Free Hardware - by R. Stallman: thoughts on Free Hardware as of June 1999.
CynApps, Inc: Cynthesis Applications - Cynlib: open source C++ hardware design class library and simulator.
IBM: DAISY - Dynamically Architected Instruction Set from Yorktown: Architecture Emulation thru Dynamic Compilation. VLIW CPU with IBM open source license. Goal: 100% compatible with Intel x86, PowerPC, S/390, Java Virtual Machine.
SystemC - Broadly supported C++ open source language and simulation kernel for modeling and implementing electronic systems.
IBM PowerPC Open Platform (POP) reference design - Free open ATX-based motherboard design to aid developers of PPC systems for Linux thin server and appliance markets.
OpenCollector Database - Site has a searchable index of many designs, tools and manufacturers.
ZDNet: News: Code-morphing: Fresh as a DAISY - There's more than one way to translate software between x86-based and VLIW (very long instruction word) processors. IBM has a code-morphing chip similar to Transmeta's.
