Trends to consider when choosing tools

As engineers, you need to incorporate advanced technologies into products to make them superior in functionality or optimized for product cost. The challenge lies in how to efficiently implement these technologies into the products while considering factors such as time-to-market, design features, testing and EMI conformity. Depending on how much upfront work has been done, implementing several iterations in the design is possible. Often, if problems are caught later in the design cycle, it becomes more difficult to redesign. Many companies know that getting a tightly integrated design tool is important, but often it is greatly compromised by cost.

There are many factors to consider during PCB evaluation. The tools to be used must be selected based on the complexity of the design. As systems grow in complexity, the need to control physical routing and electrical elements also grows, paving the way for constraint entry to become a critical path in the design process. However, too many design constraints can restrict design flexibility. Engineers must understand their design and design rules so they know when to be flexible with them.

Sylvia Teo of Mentor Graphics discusses how to address the challenges in PCB design and what factors should be considered when evaluating a PCB design tool.
