The license originally included distribution restrictions for countries not considered friendly to the US, but the source code is currently covered by the BSD license. The birth of SPICE was named an IEEE Milestone in 2011; the entry mentions that SPICE "evolved to become the worldwide standard integrated circuit simulator." Nagel was awarded the "2019 IEEE Donald O. Pederson Award in Solid-State Circuits" for the development of SPICE. SPICE inspired and served as a
