Full description
Magic is a venerable VLSI layout tool, written in the 1980's at Berkeley by
John Ousterhout, of Tcl fame. 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.
