Reduce Board Spins

Improved product quality using HyperLynx PI

Westermo's R&D division is constantly working to move the boundaries of what is technically possible for industrial data communication equipment.

The Situation

Westermo's R&D division is constantly working to move the boundries of what is technically possible for industrial date communication equipment. While it is important to be at the forefront of technology development, it is also crucial to ensure highest quality at all levels. 

Their products are smaller then any of their competitors and therefore they use High Density Interconnect PCB boards, using micro-via's and lots of layers. This means there is limited space for their Power rails. The low voltage CPU's draw large current and they need to guarantee the voltage requirements at the Pin. 

The Solution

HyperLynx PI (Power Integrity) can analyze the DC drop and AC characteristics of a PCB board. 

With the DC Drop part of the tool the voltage drop from the Power supply to device pin can be found. This cannot be done by measurements because you cannot measure under large BGA chips. They were also able to signify improve the Plane impedance using the AC analysis part of the tool.

The Results

At Westermo we make the best products. Using HyperLynx PI we can test against the worst-case scenario and add our own extra margins to it. Also we don't need to use the EMC labs as often as we did because we can simulate instead of building prototypes and measure afterwards. So time to market decreased.

We also use HyperLynx SI for Signal Integrity Analysis but Power Integrity is clearer to see than the SI part. Both tools are very helpful.

But for sure we are able to improve our already high product quality and reduce our design time.

About Westermo 

Westermo was founded in 1975. 

Profile: robust Industrial Data Communications - Made Easy.

Westermo designs and manufactures data communication products for mission-critical systems in physically demanding environments. The products are used both in social infrastructure, such as transport, water and energy supplies, and also in process industries such as mining and petrochemical. 


Virtual prototyping with HyperLynx cuts costs and design time.

HyperLynx is a complete family of analysis tools for high-speed electronic design including electrical design rule checking (DRC/ERC), signal integrity (SI), power integrity (PI) with integrated 2D/2.5D/3D electromagnetic modeling (3D EM). HyperLynx lets you discover and correct problems earlier in your design cycle using advanced simulation techniques to predict how your design will behave. Pre-route design simulation lets you explore alternatives to make informed design decisions, while post-route verification lets you perform detailed sign-off analysis before committing a design to fabrication. Increase your chance of first-pass design success to using HyperLynx to optimize your design’s performance and reliability.

HyperLynx is industry-renowned for ease of use, with automated workflows that make sophisticated analysis accessible to designers new to power and signal integrity. HyperLynx is integrated tightly with Mentor’s Xpedition and PADS Professional flows and also works with all major PCB layout systems.
