Power Integrity

Modern electronic designs include ever-increasing IC density, device-level power consumptions, use of dozens of board voltages, increasing count of PCB layout planes, complicated stackups and fine-pitch componentry.

Failure to assure adequate power delivery to each device on a design can result in Signal Integrity degradations up to and including the total failure of the design's functionality.

To assure the seamless design of a clean power system, board designers need to identify and solve complex distribution problems early in their design cycle.

Valydate Signal and Power Integrity Analysis

The application of Valydate's Power Integrity Analysis assures that:

  • Power distribution issues are highlighted prior to layout freeze
  • Quantified noise levels are visible on a part-by part level
  • 'What-if' solution alternatives are explored and decided
  • Confidence is achieved prior to artwork-commit

Valydate's Power Integrity Analysis includes the following critical ingredients:


IR Drop

  • Excessive IR voltage drop on tracks
  • Areas of excessive current density
  • Via current density
  • Ground and power plane optimization
  • Visualize noise environment

Valydate's Power Integrity Analysis comprehensively identifies all areas of IR Drop concern, and provides specific implementation guidance for available solutions.


Power Distribution Analysis (PDR)

  • Optimize on-board impedances
  • Add/ remove/change/replace decoupling caps
  • Modify routing/pads/stackup
  • Modify stitching
  • Visualize noise environment
  • Extraction of accurate via models for multi-gigahertz SI analysis

Power Integrity Analysis optimizes your decoupling scheme, stack up, ground / power plane design and via count/placement.

The experienced Valydate team uses the Mentor Graphics HyperLynx PI environment to provide comprehensive Power Integrity Analysis.

This analysis capability is agnostic to your native CAD system.

"Valydates analysis service identified real errors before we committed our design. This helped us get to market faster with a higher quality product."

Ben Brown
VP Engineering, LTX-Credence

“Valydates Schematic Integrity service has been very useful; not only in finding some issues, but also as a thorough check in verifying that other parts of the design have been done correctly.”

Milan Fait, Alcatel-Lucent HW Design

“A must have process before fabrication to avoid unnecessary re-spin”

VP of Digital Hardware Eng., ATE Solutions Provider

“The service provided to us by Valydate helps us reduce the risk of going in layout with a complex design strategic to our companys growth. Some findings in the report will save us precious time in debugging and we are confident that this first layout will even be the version released to production.”

Andre Lessard, Hardware Manager, Commscope
