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.

Still Using 1980s Formats for Design Data Handoff?

03/09/2018 | Hemant Shah and Ed Acheson, Cadence Design Systems
The IPC-2581 format was created in the early 2000s with the merger of two competing formats: ODB++ and GENCAM. The new format, the brainchild of the late Dieter Bergman, languished with no adoption until 2011, when a small group of companies created the IPC-2581 Consortium with the goal of getting this open, neutral and intelligent format adopted. The consortium has been growing steadily in recent years. Its membership now includes more than 100 associate members in addition to its more than 90 corporate members.

Who Really Owns the PCB Layout? Part 2

02/07/2018 | Paul Taubman, Nine Dot Connects
In Part 1 of this series, Paul Taubman made the bold statement that the PCB layout is just as much a mechanical effort as it is an electrical one. In Part 2, he threads the needle, explaining why he believes that a PCB truly a mechatronic design, and why mechanical engineers may be more prepared to take on the PCB layout.
