What's new in SPECTRE 21.1 Base
Here is a listing of some of the important updates made in the SPECTRE 21.1 release.
Operating System Updates
The SPECTRE 21.1 release has been developed on RHEL 7.4. Therefore, if you are using an operating system older than RHEL 7.4, you need to upgrade to RHEL 7.4 or a later version to be able to use the Spectre products.
New Spectre FX Simulator Introduced
In this release, a new next-generation transistor-level FastSPICE circuit simulator, Spectre® FX Simulator has been introduced. Spectre FX is designed for pre- and post-layout verification of large-scale DRAM, flash, SRAM, and transistor-level SoC designs. It delivers up to 3X transient simulation performance with equivalent or superior accuracy over the latest FastSPICE simulators.
Fixed CCRs in SPECTRE 21.1 Base
2460914 FX Measure files are not generated randomly after running Spectre FX
2458907 FX xprobe error occurs with the .malias statement
2450558 FX Spectre FX run with lprobe generates a fatal error message
2505332 FX The .measure statement generates NaN when the raw format is psfbin
As the industry's leading solution for accurate analog simulation, the Cadence 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.
