Sigrity^™ SPEED2000^™ technology is the first and only commercially available tool for performing transient simulation of an entire IC package and/or board design. These simulations can incorporate IBIS models. SPEED2000 combines circuit and transmission line simulations with a fast, special-purpose full-wave electromagnetic field solver that computes dynamic interactions within IC package and board structures.

Unique to SPEED2000 is its ability to perform a broad range of signal integrity/power integrity (SI/PI) studies in a single step. SPEED2000 identifies package and board resonance and radiation harmonics, and it can be used to analyze interconnect discontinuities. SPEED2000 is designed for use with popular chip-package-board design flows.

Features

• Performs time domain analysis to confirm that designs meet specified targets
• Understands complex voltage noise propagation including return path discontinuities
• Simulates simultaneous switching noise (SSN) and identifies improvement options
• Assesses various decoupling capacitor implementations
• Determines the impact of variations in stack-up, plane geometries, and I/O configurations
• Identifies package and board resonance and radiation harmonics
• Observes where noise is generated, identifies how it propagates, and determines if it stays within targeted levels
• Provides streamlined workflows for layout-based DDR SSN simulation and layout-based electrical performance checks
• Generates effective pre-layout guidelines and understands the impact of variances as the design progresses

Benefits

• First and only commercially available transient simulation environment for package/board signal and power integrity
• Single-step environment for comprehensive assessments without the need for model building
• Direct time domain observation and confirmation of system performance to confirm specs are met
• Superior accuracy enabled by advanced meshing and a combination of solvers to account for transmission line, circuit, and field effects
• Fast what-if scenario support to assess targeted design improvements
• Accurate handling of complex 3D structures such as wirebonds and vias
• Flexible 2D and 3D results visualization options including waveforms and virtual walk-through
• Unique electromagnetic control (EMC) simulation solution with support for designs with non-linear drivers and receivers
• Optimized for flows with Cadence^® SiP Layout, Allegro^® Package Designer, and Allegro PCB Designer
• Readily used in Mentor, Zuken, and Altium flows, accepting a mix of CAD databases where needed for multi-structure design support
