Spectre FX Simulator

FastSPICE circuit simulation enabling efficient design, verification,
and characterization of memory and large-scale SoC designs

Overview

FastSPICE Simulation for Memory and Advanced SoC Designers

Today's complex memory and SoC designs need high accuracy and fast simulation to verify functionality and meet chip specifications. Including post-layout parasitics in chip verification is essential, especially for advanced-node designs, to account for layout-induced effects on chip functionality. Leveraging a FastSPICE engine built from the ground up, the Cadence Spectre FX Simulator delivers the needed performance and accuracy for full-chip and subsystem-level designs.

Features

Comprehensive Pre- and Post-Layout Verification for Transistor-Level FastSPICE Simulation

Comprehensive analyses and verification capabilities – Static and dynamic circuit checking, alters, sweeps, and Monte Carlo analyses expand the scope of verification beyond functionality, timing, and power checks
Simple preset use model – Four easy-to-use presets allow quick tradeoffs across performance, capacity, and accuracy without having to tinker inside the engine
Post-layout simulation – High capacity and advanced RC reduction handle 10s of millions of RC parasitics in DSPF, SPEF, and extracted SPICE formats with both direct-inclusion and parasitic back-annotation capabilities
Debugging capabilities – Features to find and fix design problems quickly and effectively, including Tcl interactive mode for run-time debugging and Save-Restore to save computation time
Built on top of the Spectre framework – Easily consumes all the device models qualified by the world’s foundries to provide continuity with the rest of the solvers in the Spectre Simulation Platform
