UltraSim
UltraSim is a high-performance full-chip hierarchical circuit
simulation product that combines spice-precise accuracy and
virtually unlimited capacity for memory, digital and mixed
signal IC designs. UltraSim addresses the critical DSM
analysis issues such as timing, noise, power, IR drop and
reliability, including hot-carrier effects. It is the first
commercially available solution to successfully simulate a
billion-transistor memory circuit.
