SmartSpice is a commercial version of SPICE (Simulation Program with Integrated Circuit Emphasis) developed by Silvaco.
SmartSpice is used to design complex analog circuits, analyze critical nets, characterize cell libraries, and verify analog mixed-signal designs.
SmartSpice is compatible with popular analog design flows and foundry-supplied device models.
It supports a reduced design space simulation environment.
