High-performance, High-capacity FastSPICE Simulation

The Synopsys CustomSim™ FastSPICE simulator delivers superior verification performance and capacity for all classes of design, including, custom digital, memory and analog/mixed-signal circuits. The comprehensive offering includes advanced analysis options for native circuit checking, power, signal and MOS reliability analysis and mixed-signal simulation. CustomSim, in combination with its simulation environment, provides a complete mixed-signal verification solution that boosts productivity. 

Designer Productivity

Designer productivity is negatively impacted by the overwhelming number of simulations that need to be run. Not only is the number of simulations increasing, but the size of circuits, combined with extracted post-layout parasitic, is far exceeding the capacity of traditional simulation solutions. Synopsys' CustomSim FastSPICE simulator is built on best-in-class technologies that deliver increased productivity and designer confidence to address today's AMS verification challenges. 

Increased Productivity

  • Designers can use a single simulator for verifying all design types and performing advanced post-layout analysis
  • Highest-performance, highest-capacity, SPICE-accurate solution allows designers to run more simulations, faster
  • Native design rule checking avoids wasted simulation time by flagging rule violations when they occur
  • Runs simulations not previously possible, for example, full-chip post-layout functional verification with CustomSim and VCS® mixed-signal simulation
  • Reuse testbenches and measurements from pre-layout simulations for post-layout verification with back-annotation
  • Simplifies usability through a common set of inputs, outputs and device models integrated into the CustomExplorer Ultra verification environment
