Magic is a venerable VLSI layout tool, written in the 1980's at Berkeley by John Ousterhout, now famous primarily for writing the scripting interpreter language Tcl. Due largely in part to its liberal Berkeley open-source license, magic has remained popular with universities and small companies. The open-source license has allowed VLSI engineers with a bent toward programming to implement clever ideas and help magic stay abreast of fabrication technology. However, it is the well thought-out core algorithms which lend to magic the greatest part of its popularity. Magic is widely cited as being the easiest tool to use for circuit layout, even for people who ultimately rely on commercial tools for their product design flow.

AMD and Intel Announce Settlement of All Antitrust and IP Disputes
Intel Corporation and Advanced Micro Devices (NYSE: AMD) today announced a comprehensive agreement to end all outstanding legal disputes between the companies, including antitrust litigation and patent cross license disputes.
In a joint statement the two companies commented, "While the relationship between the two companies has been difficult in the past, this agreement ends the legal disputes and enables the companies to focus all of our efforts on product innovation and development."
Under terms of the agreement, AMD and Intel obtain patent rights from a new 5-year cross license agreement, Intel and AMD will give up any claims of breach from the previous license agreement, and Intel will pay AMD $1.25 billion. Intel has also agreed to abide by a set of business practice provisions. As a result, AMD will drop all pending litigation including the case in U.S. District Court in Delaware and two cases pending in Japan. AMD will also withdraw all of its regulatory complaints worldwide. The agreement will be made public in filings with the Securities and Exchange Commission.
