Agenda

• Engineering Needs• Traditional Landscape• Innovation | In the EDA Industry• Innovation | Bridging the Software and Hardware Gap

• Integrated Design and Test

4

Engineering Needs | The Wish List

• Meeting Product Release Dates & Engineering Deadlines• Meeting PCB Performance Targets• Meeting Engineering Development Costs• Increased Innovation• Improved Design and Test Process• EASIER path to final product

5

Traditional Landscape | Problems for the Engineer

• Engineers & organizations have different tools for each task

• Difficult communication between engineers• Difficult to manage the complete design flow• Difficult to address transfer from design to manufacturing• Difficulty to incorporate feedback into improvements

• This is NOT the best practice in design, validation or production

6

PROPINQUITY

Noun1.propinquity - the property of being close togetherProximity, nearness, closenessThe spatial property resulting from a relatively small distance; "the sudden closeness of the dock sent him into action"

THE REALITIES OF DESIGN

The World Is Flat 3.0: A Brief History of the Twenty-first Century (Paperback)by Thomas L. Friedman (Author)

Traditional Landscape | Result of No Best Practices

• Difficulties for participants leading to production and sale of a product:§ Design Group§ Test Group§ Manufacturing Group

• Products do not meet development cost targets§ 45% to 64% of products miss cost targets*

• Designs require as many as 3 re-spins§ 21% to 39% of designs require as many as 3 re-spins*

• This results in costly, longer design and production cycles
