Sigrity SI/PI Analysis Overview
Companies designing complex PCBs are faced with power integrity (PI) and signal integrity (SI) issues driven by increasing data transmission rates combined with decreases in power-supply voltages and denser, smaller geometries. Increased functionality and smaller product geometries are making PCBs more complex. To address these issues, you need advanced PI and power-aware SI tools that can be used throughout the design process.
Power Integrity
Cadence® PI solutions, based on Sigrity™ technology, provides signoff-level-accurate system-level power integrity analysis for AC and DC power of PCBs. Each tool seamlessly interfaces with our Allegro® PCB design solutions.
Signal Integrity
Cadence power-aware SI tools, based on Sigrity technology, provide signoff-level accurate SI analysis for PCBs. 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 Allegro PCB physical design tools to create a complete power-aware design and SI analysis solution for the entire design team to understand SI design considerations.
