iCD Adds Coplanar Waveguide Planner to iCD Design Integrity Software


Reading time ( words)

In-Circuit Design Pty Ltd (iCD), Australia, developer of the iCD Design Integrity software, has released the new iCD CPW Planner to be incorporated as part of the 2017 release of its suite of high-speed PCB design tools.

“Coplanar waveguides (CPWs) have been used for many years in RF and microwave design as they reduce radiation loss, at extremely high frequencies, compared to traditional microstrip. And now, as edge rates continue to rise, they are coming back into vogue,” said Barry Olney, CEO of iCD. “Today’s high-speed, fast rise-time serial interfaces are prone to excess loss, in the transmission lines, which is a major cause of signal integrity issues. Minimizing this loss reduces jitter and improves the bit error rate (BER) and inter-symbol interference (ISI).” 

The CPW offers several advantages over a conventional microstrip transmission line: 

  • Simplifies fabrication.
  • Facilitates easy shunt as well as series surface mounting of active and passive devices.
  • Can eliminate the need for via holes and wraparound edge plating.
  • Reduces radiation loss at very high microwave frequencies.

Furthermore, the impedance is determined by the ratio of trace width to clearance, so size reduction is possible without limit, the only penalty being higher losses.

“The new iCD CPW Planner has five popular generic CPW structures that model single and dual (differential) CPWs, with and without ground reference planes, plus a dual Coplanar Strip (CPS) which has no ground reference plane or copper pours. Materials maybe inserted, from the extensive iCD Dielectric Materials Library featuring over 30,850 rigid and flexible materials up to 100GHz, to dramatically increase accuracy at extremely high microwave frequencies,” said Olney.

Mentor recently released the newest version of its HyperLynx signal integrity software. This version may be the first SI tool in the industry to fully automate SERDES design channel validation. I spoke recently with Chuck Ferry, product marketing manager with Mentor, about the new HyperLynx and some of the new serial link design capabilities that customers have been demanding.

Julie Ellis: TTM’s Interface Between Designer and Fabricator

04/04/2018 | Barry Matties, Publisher, I-Connect007
As a field application engineer for TTM, Julie Ellis sees the problems that can occur between circuit board designers and manufacturers. Barry Matties spoke with Julie at the AltiumLive event in Munich about the age-old problem of throwing designs “over the wall,” the trend towards HDI, and what advice she would give new designers.
