As the industry’s leading solution for accurate analog simulation, the Cadence^® Spectre^® Simulation Platform contains multiple solvers to allow a designer to move easily and seamlessly between circuit-, block-, and system-level simulation tasks. The foundation of the platform is a unified set of technologies shared by all of the engines—the parser, device models, Verilog-A behavioral modeling, input data formats, output data formats, etc.—thereby guaranteeing consistent and accurate evaluation methods regardless of the simulator selected.

Spectre Simulation Engines

• Spectre Accelerated Parallel Simulator (APS) analog simulator provides Spectre accuracy with a 5X reduction in simulation time as compared to the original Spectre engine
• Spectre X Simulator solves large-scale verification simulation challenges with up to 10X speed and 5X capacity improvements as well as scalable and massively parallel simulation for cloud computing
• Spectre Extensive Partitioning Simulator (XPS) provides FastSPICE high-performance and capacity simulation needed to handle memory and mixed-signal designs
• Spectre AMS Designer, Cadence’s mixed-signal, mixed-language, mixed-level, functional, behavioral, gate-level, and transistor-level simulator, is used in conjunction with the Cadence Xcelium^® simulation technology

Spectre Simulation Options  

• The Spectre RF Option provides accurate and fast simulation for RFIC circuits. The option includes periodic steady-state, small-signal, and noise analyses along with harmonic balance analysis capabilities to maximize performance without loss in accuracy
• The Spectre CPU Accelerator Option enables multi-thread simulation for transient and periodic steady-state analysis, extremely useful for verification of parasitic back-annotated designs across multiple CPUs
• The Spectre Power Option is the dedicated transistor-level electromigration and IR drop analysis that is used as the analysis engine inside the Cadence Voltus^™-Fi Custom Power Integrity Solution

Spectre Simulation Licensing

• Cadence provides a unique multi-mode simulation (MMSIM) license that can enable any part of the platform on demand, so you can focus on simulating your design without worrying about which licenses are required for various simulation types
