- Ensure both electrical and thermal integrity of PCB
- Reduce cost while maintaining performance by optimizing decoupling capacitorsEnsure both electrical and thermal integrity of PCB
- Quickly and accurately analyze large PCBs for both AC and DC power integrity
The team-based approach to power integrity starts early in the design process when selecting decoupling capacitors and adding them to the schematic. The Cadence® Allegro® Sigrity™ PI analysis enables passing this design intent to layout designers through constraints and much more. You are further enabled with DC analysis technology and then PI experts can step in and validate the finalized design for AC and DC performance, ensuring that the power delivery network (PDN) is working to spec and fully optimized.
With low power becoming a high priority for electronic designs, power integrity can no longer be an afterthought. A constraint-driven power integrity flow keeps PDN design as a forethought throughout the design process. The Cadence Sigrity team has expanded on the proven constraint-driven flow for signal integrity and recently added constraint sets that are specific for power integrity. Allegro Sigrity PI technology supports the full design flow by enabling the capture of PI Csets early and guiding PCB designers to follow the constraints associated with decoupling capacitor selection and placement. But the PCB designer’s job doesn’t stop there. When using Allegro Sigrity PI, PCB designers can run IR drop analysis and find locations where the PDN cannot deliver sufficient voltage. So not only are they able to properly decouple a design, they are empowered to address first-order DC concerns.
