Computer cluster for IC and antenna design
Modern mixed-mode IC design as well as design of multi-antenna structures and phased-arrays require very powerful computers to run CAD tools. Our dedicated server cluster consists of five 32-CPU servers with 512Gb of memory each, and over twenty desktop computers.
