As the industry's leading solution for accurate analog simulation, theCadence Spectre Simulation Platformcontains 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 SPICE 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.
The simulator uses improved algorithms that offer increased simulation speed and greatly improved convergence characteristics over SPICE. Besides the basic capabilities, the Spectre circuit simulator provides significant additional capabilities over SPICE. Verilog-A uses functional description text files (modules) to model the behavior of electrical circuits and other systems. Spectre RF Simulation option adds several new analyses that support the efficient calculation of the operating point, transfer function, noise, and distortion of common RF and communication circuits, such as mixers, oscillators, sample holds, and switched-capacitor filters.
Cadence technology platforms, including Xcelium Logic Simulation, Liberate Trio Characterization Suite, Legato Reliability Solution, Virtuoso ADE Product Suite, Voltus-Fi Custom Power Integrity Solution, and the Virtuoso RF Solution, to provide the industry's most comprehensive cross-domain simulation solutionThe Spectre Simulation Platform delivers an indus-try-leading set of technologies for a comprehensive design and verification solution that provides SPICE, radio frequency (RF), FastSPICE, and mixed-signal simulators in a unique shared licensing package. This unified solution delivers scalable performance and capacity, thus providing robust verification of analog, RF, memory, custom digital, and mixed-signal silicon realization.
