A special partnership collaboration to deliver

Signal and Power Integrity Training Courses

CommTech teamed up with Eastronics, Tektronix and Rohde & Schwarz to collaborate in delivering Signal Integrity training courses to the Hi-Tech and the Defense Industries in Israel.

“There are two kinds of designers, those with signal-integrity problems and those that will have them.”

Examples of Design Issues Addressed During the Course

Amplitude Problems

Amplitude problems include
ringing (oscillation), “droop” (decreased amplitude at the start of a pulse), and “runt” pulses (those which don’t reach full amplitude).

Amplitude Problems

Ground Bounce

Ground bounce, caused by excessive current draw (and/or resistance in the power supply and ground return paths), can cause a circuit’s ground reference level to shift when current demands are high.

Ground Bounce

Edge Aberrations

Edge aberrations can result from board layout problems or from improper termination or even quality problems in the semiconductor devices.
Aberrations can include preshoot, rounding, overshoot, ringing, and slow rise time.

Edge Aberrations

Crosstalk

Crosstalk can occur when long traces running next to each other couple their signals together through mutual capacitance and inductance.

Crosstalk

Reflections

Reflections can be caused by termination and board layout problems, where the outgoing signal bounces back toward its source and interferes with subsequent pulses.

Reflections

Jitter

Jitter is defined as edge placement variations from cycle to cycle. Some important causes of jitter are noise, crosstalk and timing instability. This can affect timing accuracy and synchronization throughout a digital system.

Measurements

Simulations

Course Overview

The course duration is 30 academic hours and will be delivered over 6 meetings of 5 academic hours each
This is a comprehensive and intensive course. (see the course syllabus)
The course, is presented by  leading technical experts from industry and academia with many years of experience. (see Lecturers)
The topics include SI analysis, guidelines, simulation, and verification.
Theoretical topics include power, frequency spectrum, phase/amplitude response of linear systems, signal distortions, time-domain reflections, impedance matching considerations, noise, electromagnetic coupling and interference (EMI), and fast time-domain measurements and de-imbedding.
The objectives are to establish a sound basis for signal and power integrity design rules, checking by 3D electromagnetic simulation SW and verification by hands-on measurements.
Hands-On practicing is important. The course includes a series of practical demonstrations using modern test and measurement equipment.
