You have a design that you want to optimize using different simulation setups or even different schematics. For example, say you want to optimize an amplifier's input and output matching networks to meet both S-parameter and large-signal specifications simultaneously. How do you do this?

There are two example workspaces that show ways of doing this.  If your objectives are relatively simple, for example, just S-parameters and a large-signal simulation, you may be able to use just one schematic.  

If you have more complex objectives and prefer to optimize a design using multiple schematics, the Sequencer can be used. Registered users can learn more and get two example workspaces here. http://bit.ly/2bxYAar

SIPro Introduction

Posted by KeysightEEsofEDA Employee Sep 19, 2016

 

The overall signal quality depends on both the Signal Integrity(SI) and the Power Integrity(PI) engineers success. In this video, you will learn more about the challenges you might face, such as the impact of non-ideal ground planes, skew matching, and densely routed-boards.

 

 

You will also learn techniques to use the new signal integrity EM Analysis tool that can help you achieve your design analysis goals in both pre-layout and post-layout simulations.

You’ve just downloaded Keysight ADS, and now you’d like to get up and running in under 10 minutes. In this short video, you will learn how to navigate through the ADS environment to create a new workspace, build a new schematic, and run a simulation. Through an example, you will also learn how to tune your design to optimize the performance. 

Design engineers often have a long laundry list of “needs and wants.” When it comes to simulation, that list most certainly includes greater accuracy and convenience. The newest release of the Modelithics COMPLETE Library, version 16.2, promises to deliver just that.

Genesys

The Modelithics COMPLETE library, specifically designed for use with Keysight EEsof EDA Genesys RF simulation and synthesis software, contains RF/microwave models for transistors, diodes, amplifiers, entire passive component families, and more. Using these convenient models, designers gain the ability to simulate with unmatched accuracy. Version 16.2 of the Modelithics COMPLETE Library features 29 new models from 14 different vendors, including substrate scalable Modelithics Microwave Global Models, single substrate models, S-parameter models, and nonlinear simulation models. For added convenience, the update library even allows you to customize the timing of your license expiration notification.

This example will introduce the basic structure of ADS workspaces, schematics, and displaying simulation results.The step-by-step screenshots demonstrate how to get started using ADS without assuming any prior experience.

I highly recommend this new 10-minute video on custom filter design. How-Siang Yap, RF/MW engineer, breaks his method down step-by-step and shows us how to:

  1. Shape custom filter responses
  2. Choose realizable filter topologies
  3. Transform topologies for easier realization

 

As a mathematician I loved his introduction to the method of transforming topologies. He likened it to a Rubix’s cube, where mastery takes planning and practice. He shows how easy it is to perform transforms in Keysight Genesys Software. And my favorite was when he showed how to choose a transform that gives you both symmetry in the topology and the filter response, just like the Taj Mahal. You’ll have to watch the video to understand the analogy.

 

Design engineering takes knowledge and creativity to create something of value & beauty, and How-Siang shows us how in his latest video.

Unlike traditional RF, Microwave and Analog filter designs that start from a template response and topology, such as Chebyshev and Butterworth, this custom filter design technique is based on Direct or Exact Synthesis in which the filter response is first shaped and customized to meet specifications before a suitable topology is extracted and transformed for the most economical realization.
