SI/PI Analysis

Companies designing complex semiconductor packages are faced with power integrity (PI) and signal integrity (SI) issues driven by increasing IC speeds and data transmission rates combined with decreases in power-supply voltages and denser, smaller geometries. Stacked die and packages, higher pin counts, and greater electrical performance constraints are making the physical design of semiconductor packages more complex. To address these issues, you need advanced PI and advanced power-aware SI tools that can be used throughout the design process

Cadence^® package analysis and assessment tools, based on Sigrity^™ technology, provide IC package design, analysis, and model extraction capability—and can exchange data with Allegro® Package Designer Plus and its SiP Layout Option. Assessment capabilities allow you to quickly spot potential SI/PI issues. Model extraction capabilities provide unique full package model extraction with accuracy into the multi-gigahertz frequency range.

Power Integrity

Cadence PI solutions, based on Sigrity technology, provide signoff-level accuracy for AC and DC power analysis of IC packages. Each tool seamlessly interfaces with Cadence IC packaging physical design solutions.

Signal Integrity

Cadence power-aware SI tools, based on Sigrity technology, provide signoff-level accurate SI analysis for IC packages. Signoff-level SI accuracy requires modeling and analysis of not only the signals, but also the power/ground network that provides the current return path. Our power-aware SI tools interface seamlessly with our Cadence IC packaging physical design tools to create a complete power-aware design and SI analysis solution.
