Overcome Challenges of Your Highly Constrained PCB Designs

Layout constraints are an essential part of a PCB design. As the technology in modern electronic devices has become more complex (e.g. increasing speed, decreasing rise time and supply voltage values), signal integrity issues have become a primary concern. For many designs, this means a large percentage of nets require PCB layout constraints to meet signal integrity requirements. This brings two major challenges: creating a proper set of layout constraints for your design and applying those constraints during the PCB layout design process. This paper shows how to address the challenges of highly constrained designs.

Removing the Gap Between ECAD and MCAD Design

For ECAD and MCAD to collaborate in “real-time” a direct method of communication that facilitates a shared flow of data back and forth between design teams is required. This flow must support “what-if” scenarios of design baselines and change proposals along with the ability to counter-propose changes. Once design agreements are made, the flow must also dynamically update the design databases. This unique ECAD-MCAD (EDMD) collaborative environment has not been available until now. This desktop PCB design provides a real-time integrated ECAD-MCAD collaboration environment that enables Electrical and Mechanical design teams to work together throughout the entire design process.

Developing Smart and Affordable Intelligence, Surveillance and Reconnaissance Technologies: Five Trends to Watch

The demand for intelligence, surveillance and reconnaissance (ISR) technology and infrastructure is growing significantly. For example, in the 10 years from 2002 to 2011, U.S. Defense spending on ISR grew by a factor of six, compared with relatively flat defense spending overall [House Permanent Select Committee on Intelligence, 2012]. Similar patterns of spending can be seen around the globe. Simulation-based engineering has long played a role in advancing ISR technology development — from unmanned systems to antennas to systems and embedded software. The value proposition has long been proven.

What They Didn’t Teach You in Engineering School About Heat Transfer

Until recently, the commercial software available for CFD typically has been geared towards specialists, limiting its widespread use. Besides being expensive, these tools have either been difficult, cumbersome or time-consuming to use. As a result, engineering analysis for applications such as heat transfer traditionally have been carried out by specialists in analysis departments, separate from mainstream design and development departments.

CFD for Mechanical Design Engineers - “A Paradigm Shift for Better Design”

There is demonstrated, real value in using CFD to analyze products earlier in the product development lifecycle than has been possible under the common scenario of reserving this important analysis regimen for CFD specialists.

Solving the System-Level Thermal Management Challenges of LEDs

As thermal management continues to be critical to LED performance, thermal simulation is playing an increasingly important role in LED system design. New generation CAD-embedded thermal and fluid simulation software makes it possible for LED systems designers to diagnose thermal problems, evaluate a large number of design alternatives quickly, and iterate rapidly to an optimal solution. Another bonus? Having a deep understanding of the computational aspects of fluid dynamics is no longer a requirement...
