About Stixu
Stixu is a tool for designing and validating CMOS logic circuits.
The tool was conceived and developed by Nick Overacker, an Oklahoma State University Computer Engineering graduate currently living in Japan.
The user interface was designed and implemented with the help of Miho Kobayashi, a Kansai Gaidai University graduate, former OSU exchange student, and freelance web designer.
The default canvas palette was borrowed from Paul Tol's work.
The alternate "Sorcery" palette was inspired by the Magic VLSI layout tool.
