Power Integrity Analysis at System Level

Power Integrity ( PI ) Analysis at System Level 

Power Integrity is not a new term in high-speed digital design and analysis. Ever increasing count of PCB layout planes, form factor limitation, high IC density, cost constraint are few of many factors which results in complex electronic designs.

Power integrity ( PI ) Analysis is sometimes assumed as a sub discipline of Signal Integrity, but as they are coherently related they have distinctive features of their own which are to be done in different ways.  Signal Integrity analysis is based on transmission lines whereas in Power Integrity analysis we are dealing with power distribution through transmission planes.

Power Integrity can identify the potential problems and with appropriate modifications and validations the analysis can be done again, this trial and error approach helps to identify problem on virtual prototypes and saves in turn cost of actual manufacturing and later re-spin of boards.

As explained in one of the white papers as per IEEE EMC symposium the complete definition of power integrity for a power delivery network can be defined as:

  • A power delivery network (PDN) has to deliver sufficiently clean power supply to ICs.
  • The PDN has to provide low noise reference path to signals.
  • The PDN should not radiate excessively.

Depending on the above definition the Power Integrity analysis has different types of simulations which can be listed as:

  • DC Power Integrity ( IR-Drop analysis) : Analysis of trace and plane shapes to determine how much voltage is lost due to the resistance of copper.
  • Decoupling analysis : To meet low impedance requirements.
  • Noise analysis : Noise analysis of IC Power pins or from via to another.

For high-speed and highly-reliable PCB design it is essential to perform pre-layout PDN analysis and Power Integrity analysis is a must for it.

Outsourcing Your Printed Circuit Board Design

A start-up business or company deals with many risks . With limited time , money and resources to make a  product and deliver it with quality pose many challenges.

The complexity of development of products starts from idea to designing , prototyping, manufacturing and finally going into production. The  product development  cycle requires  expertise in all fields and in-depth knowledge of many technologies. Smaller start-ups and product companies who do not possess in depth knowledge of the product design and development turns to  other companies for their requirements. This helps the start-ups to focus on their strengths and utilize other companies strength to reduce the time to market  and build a better product.

Product development broadly can be divided into following stages :

1) Design phase : Design Feasibility and Cost Analysis , regulatory requirements, analysis of reliability and availability

2) Prototype and Validation phase : PCB design, embedded software validation

3) Manufacturing phase

Each of these phase requires expensive tools and capital equipment expenditures which can be lowered significantly if these can be outsourced to the external custom electronic design team that has the required tools and experience. This will in turn reduce the operational cost of the start-up business and help them to  focus on their strategy and lean them to profitability.

Outsourcing design requirements encourages accountability as experienced and reputed EMS team will be working on the project which in turn minimizes the chances of failure.

The high costs of CAD tools, maintenance and staff training  also make a good case for this approach. However, handing over your latest concept to a design bureau is not a decision to be taken lightly.  The design bureau should be capable with proven experience in delivering the product or design.

Outsourcing electronic design or product design has many direct benefits some of which are less time to market, less operational cost, more time for focusing on actual  product idea and last but not least delivering quality product.

Argus has long history working with some of the biggest names in the electronics industry, and have vast experience working with engineers and project managers who favor the ‘outsource’ model.  Thus the outsourcing model is recommended in electronic design and product design  fields and is a proven model which can be used to benefit any product development company.
