Fidus delivers power distribution network design consulting to meet Power Integrity (PI) requirements in electronics products. Inadequate PI can cause intermittent failures or poor performance. Arbitrary inclusion of a large number of capacitors is not only expensive, but can lead to undesirable resonances defeating the purpose. Further, in mixed signal designs, noise on power rails can increase jitter in clocks and affect sensitive Radio Frequency (RF) signals adversely.
Working closely with customers, Fidus assesses specific power distribution requirements and cost budget. The data is used in a PI simulation tool, developed by the Fidus Signal Integrity team, which can fully analyze a board-level power distribution network based on either the transmission line mesh model or the cavity model. For complex designs and those that include package and board, a full 3D EM simulation is carried out leading to:
- PCB Layer stack-up selection for optimum power distribution
- Minimum required power and ground plane areas
- Number, size, values, and locations of decoupling capacitors
Fidus takes the guess work out of power distribution design, resulting in products that provide clean power delivery to the Integrated Circuits, a low impedance low noise reference path for other signals and reduced electromagnetic emissions. Fidus can also perform experimental characterization of PI through Vector Network Analyzer (VNA) measurement of rail impedance and noise injection into power rails.
