This Seminar will give you insights into:
• New EM simulator design tools for signal and power integrity applications
• Making accurate Power Integrity Measurements using existing and new Oscilloscope tools
• High-speed Oscilloscope probing techniques to make more accurate measurements
• Arbitrary Waveform Generators; how to select the right one for your Digital, optical or electrical
Design Topic 1: Power & Signal Integrity Simulation “Insight on Power Integrity & Signal Integrity before the first prototype”
It has become much more important to get higher frequency s-parameters for PCB accurately due to ever increasing data rates. ADS 2016 features a host of new technologies designed to improve accuracy of PCB simulations, including two electromagnetic (EM) software solutions specifically created to help signal and power integrity engineers.
This solution consists in 4 new EM simulators:
• DC IR drop analysis • AC PDN impedance analysis
• Power plane resonance analysis
• Power-aware signal integrity analysis
In this session, you will learn the new innovative pure EM based SIPro and PIPro composite technologies for designing high speed digital boards. SIPro and PIPro provides a cohesive workflow with ADS for signal integrity and power integrity applications.
Topic 2: Power Integrity Measurements “Power Integrity Measurements – Debugging DC Voltage Lines using Oscilloscopes”
The DC power supply is receiving more and more scrutiny as supply voltages continue to get smaller. Supply tolerances are getting tighter as users try to decrease power, increase yield and minimize supply induced signal noise. This paper will discuss tools and techniques for making power integrity measurements such as ripple, noise, spikes, compression, static/dynamic load response and supply induced signal noise and signal jitter. Included is a discussion of the effects of oscilloscope noise, probe noise, probe attenuation ratio, offset range, input range, connection technique and measuring supply/signal crosstalk. Paper Goals & Outcome:
• Debug and test PDN’s (power distribution networks) with more precision, accuracy and confidence.
• More easily isolate root cause of PDN noise.
• Avoid false negative (or positive) test results.
• Become aware of specialized tools that can make your job easier.
Topic 3: High-Speed Oscilloscope Probing – Single-ended or Differential? “Gain Insights into High Speed Probing and learn how to make the most accurate measurements”
New active probe architectures for oscilloscopes make gigahertz signal-integrity measurements easier and more accurate, but only for those who understand how the probes work, and the trade-offs among the topologies. In this module you will learn about:
• Important probe characteristics
• Single-ended probes
• Solder-in and ZIF differential probes
• Browser differential probes
• Offset in differential probes
• Probe input impedance profiles
Topic 4: Fundamentals of Arbitrary Waveform Generation “Understand Arbitrary Waveform Generators to select the right one for your Digital, optical or electrical Design”
Testing an electronic device or system implies applying the right stimuli to the device or system under test and analysing the resulting behaviour. In some cases, stimuli come from the real world, but in most situations a set of signals must be supplied by an instrument such as an arbitrary waveform generator (AWG) to ensure repeatable and deterministic testing. As devices and interfaces become faster and more complex, flexibility of test instruments becomes more and more important. An AWG allows you to generate the most versatile signals. This paper will present the criteria to consider when choosing an AWG for digital applications, optical and electrical communication, advanced research, wideband radar and satcom. You will learn what is important for the generation of digital, multi-level and PAM-4 signals, wireless and modulated waveforms, and multi-carrier as well as coherent optical signals.
