CustomSim

High-performance, High-capacity FastSPICE Simulation

The 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

Accelerate Innovation with Analog/Mixed-Signal Verification

Synopsys addresses the most critical issues in AMS verification. HSPICE® is employed by leading semiconductor foundries to provide designers with the gold standard for accuracy in device modeling and precision circuit simulation. FineSim® is a multi-core accelerated circuit simulator well-suited for simulation of large, complex analog circuits, as well as DRAM/SRAM/Flash memory design. The CustomSim™ FastSPICE simulator delivers superior transistor-level verification performance and capacity for various classes of design, including custom digital, memory, and analog/mixed-signal circuits. HSPICE, FineSim, and CustomSim support a comprehensive set of reliability and variability analysis features, with the cornerstones being high-performance engines and common modeling and analyses technologies. For full-chip mixed-signal verification, Synopsys’ VCS® AMS mixed-signal verification solution combines the industry’s fastest RTL and circuit simulation engines (VCS, CustomSim or FineSim) to deliver the best performance and capacity for mixed-signal SoC regression testing for advanced functional and low-power verification.
