iCD Products

iCD Stackup Planner

Controlled Impedance Planner - Offers Engineers and PCB Designers unprecedented simulation speed, ease of use and accuracy at an affordable price.

iCD PDN Planner

AC Impedance and Decoupling Planner - Analyze multiple power supplies to maintain low impedance over the entire frequency range dramatically improving product performance.

iCD CPW Planner

Coplanar Waveguide Planner - Model microstrip Coplanar Waveguides to reduce radiation loss, of high-speed serial links, significantly improving product performance.

High-Speed Design Features

HDI Via Span Definition

The Via Span Definition dialog allows the user to insert PTH, Blind or Buried Microvias that span two or more internal layers.

iCD Termination Planner

Extracts IV curves from IBIS models. Calculates the required series terminator of the distributed system including loads.

iCD Materials Planner

Compare dielectric materials based on manufacturer, fabricator, frequency, Df and Dk.

Matched Delay Optimization

Relative signal layer propagation. Ideal for DDRx trace delay matching.

Electromagnetic Radiation

The Electromagnetic Emissions (EMI) plot represents the projected maximum radiated noise if a high-speed signal excites the plane resonance at a particular frequency.

Mirror Stackup

Stackup Mirroring allows the user to cut data entry time in half. Create the top half of a symmetric stackup, right click on the stackup, and select "Mirror Stackup".

Multiple Differential Pairs

Insert multiple Differential Pair definitions per layer. This is the first Impedance Calculator/Stackup Planner that allows the user to setup as many different impedances as you like on the one layer or every layer of the stackup.

Coplanar Waveguide Planner

Model microstrip Coplanar Waveguides to reduce radiation loss, of high-speed serial links, significantly improving product performance. Insert solder mask and dielectrics from library.

Dielectric Materials Library

Over 31,250 rigid/flex materials to 100GHz. The DML improves the accuracy by using the same core, prepreg and soldermask materials stocked by the PCB Fabricator.

Heads-up Impedance Plots

The Z plots are simulated by multiple passes of the field solver to create heads-up graphs of how to adjust the variables to achieve the desired impedance.

Signal Flight Time

Extracts the inductance and capacitance and the propagation velocity of each layer in the stackup. The user needs enters the trace length for each signal layer, then total flight time is then calculated.

S-Parameter Import

Import Sparam Models from Vendors. The Scattering Parameter (S-Param) import to the iCD PDN Planner is via the Touchstone 2-Port (s2p) format.

PDN Capacitor Library

The iCD PDN Planner Starter Capacitor Library contains over 5,650 SMD Ceramic and Tantalum capacitors, extracted from SPICE models, from ATC, AVX, Johanson, Kemet, Murata, Samsung,Taiyo Yuden and TDK range that are readily available.

  • What customers say about our articles:

  • I did a video board with DDR2 memory a while ago on Altium. Thank you for your routing tips for DDR2, which I got off the internet. They helped a lot and the board now works like a dream. I will continue to follow your articles in the PCB magazine. It is people like yourself that make life so much easier for the rest of us. Thanks once again for your insightful articles in The PCB Design Magazine.

  • Steve Knobel, Senior CAD Designer, CID+, Advanced Technologies & Engineering

  • 'Just a quick note to let you know we really like this program you guys made. It's doing a great job for us.'

  • Michael Ingham - Spectrum Integrity Inc

  • 'The iCD Stackup Planner has proven very useful especially for highlighting the affects of builds and other amendments on the calculated impedance to the customers. It is both flexible and concise with only a very short learning curve required to use confidently.'
