Workshop on High Speed Signal Integrity

I would be conducting a day-long, hands-on workshop on High Speed Signal Integrity design at Keysight Technologies, Bangalore office. First session is scheduled on 17th August 2017.

This workshop is complimentary but requires prior registration to receive a formal invite.

Workshop Agenda:

Pre Layout SI

  • Designing VIAs for optimum High Speed performance
  • Controlled Impedance Line Design
  • Channel Simulation Basics
  • High Speed Serial Link Simulation
  • Batch Simulation
  • IBIS-AMI Simulation
  • Eye Optimization

Post Layout SI

  • BRD/ODB++ Layout Import in ADS
  • Post Layout SI Simulation with SIPro
  • Channel Simulation with Post Layout Data

If you are interested to attend the same, you can drop a mail with your complete contact details at “” or leave your details in the comment box….

Happy Designing…!!!

P.S. If we are not able to accommodate you for the 1st session due to capacity limit or you are not able to make it due to other engagements then we will surely accommodate you in one the future  sessions which are likely to happen shortly.

Automatic VIA insertion in ADS Layout

Creating multilayer layouts can be lot of pain at times essentially because of transitions between layers.

With ADS2011 release onwards, ADS provides an easy way for designers to create their own automatic via insertion config file which can be created and used by designers even if they do not get this support from foundry or PCB fab people.

Using this feature, designers can route their layouts lot easier and VIAs will keep coming whenever layers are changed for routing purposes.

You can watch this simple video to learn more about this nice feature:

Multilayer VIA simulation using ADS (Momentum & FEM)

Simulating accurate VIA performance is one of the key to perform good multilayer board design for RF/uWave as well as High Speed Digital applications to maintain Signal Integrity.

Over the years designers tend to believe that only full 3D simulators i.e. FEM or FDTD based solvers can offer accurate simulations for multilayer VIA structures and complex 3D simulations are performed which can take up to several hours to simulate VIA structures causing increased turn around and design iterations.

With newer ADS releases it is now possible to simulate multilayer VIA structures accurately and efficiently using Method of Moments (MoM) i.e. ADS Momentum largely due newer algorithms which are incorporated in ADS to handle such geometries very accurately.

Also newer ADS release comes with a very nice utility to draw these multilayer VIAs pretty quickly and efficiently. Attached technical note offers step by step procedure to use the multilayer VIA utility to draw these kind of VIA structures and discusses simulation of multilayer VIA using Momentum & FEM solver which are fully integrated into ADS environment. Comparison of results using Momentum & FEM solvers are also provided.

Happy Designing…..
