ATopTech was founded in 2004 by a team of leading EDA physical design implementation experts expressly to build new technology, from scratch, to deal with these issues design at 65nm and below. Aprisa, the result of these efforts, shipped to customers in December 2006 and has been used successfully in several hundred tapeouts to date. Aprisa is currently in active use in several 28nm design efforts. Apogee, launched in 2009, is a complete top down floorplanning and chip assembly tool that complements Aprisa. It has been used successfully in several dozen tapeouts.
