Cadence Allegro Power Delivery Network analysis

Cadence Allegro Power Delivery Network Analysis
Cadence Allegro PCB Power Delivery Network (PDN) Analysis is a unified environment that allows designers to create power guidelines early in the design process, make changes on-the-fly, and optimize the PCB stack-up.

Power delivery network (PDN) analysis is a critical component of PCB design. Higher frequency designs being powered by lower voltages leaves little margin for IR drop or ground bounce. PCB designers and electrical engineers can now benefit from a tightly integrated Allegro® PCB Designer and PCB PDN analysis environment, which enables rapid design modification and analysis iterations without having to go through time-consuming and error-prone translations.

Allegro PDN provided a unified design and analysis environment that lets you work early in the design process (pre-netlist) to create abstract plane definitions with virtual source and sink components, to create plane design guidelines, and to optimize the PCB stack-up. Its post-layout analysis provides accurate modeling of the details of carved-up power and ground planes. Impedance is measured at all power and ground planes, ensuring that stable and sufficient power can be delivered efficiently. Any modifications required to the post-route design can be tested on-the-fly without translation, allowing you to achieve PDN closure in compressed PCB design development schedules.

Benefits:
  • Provides an accurate full-wave solver for planes
  • Easy pre-netlist analysis guides plane design and optimizes PCB stack-up 
  • Voltage drop combined with current vectors helps identify problem areas 
  • Analyzes impedance for every power and ground pin on the PCB 
  • Optimizes decoupling capacitor values and locations
  • Integrates seamlessly with Allegro PCB design and signal integrity analysis environments
