Signal Integrity

Signal integrity covers all the issues about single ended and differential signal propagation from the transmitter to the receiver, including problems such as impedance control, discontinuities, reflections, topology, terminations, losses, ISI, jitter, eye diagrams, cross talk and ground bounce.

Power-Aware Analysis Solution

By reviewing the classic (or traditional) SI methodology, analyzing high-speed design flows, and examining what is employed in Cadence® Sigrity™ power and signal simulations using the SPEED2000™, PowerSI®, Transistor-to-Behavioral Model Conversion (T2B™), and SystemSI™ tools, this paper explains how a general power-aware SI solution not only should be capable of performing SSN simulations, but also capable of creating and extracting signal and power analysis-required models and running design checks with power-aware constraints. Providing such a complete, or true, “power-aware solution” gives designers the confidence to produce high-quality designs.

Cadence: Addressing the “Power-Aware” Challenges of Memory Interface Designs

One of the toughest challenges in designing memory interfaces is accurately measuring timing while also considering fluctuations in power and ground rails due to simultaneously switching signals. Signal integrity (SI) engineers are increasingly insisting on “power-aware” SI analysis, where the effects of signal and non-ideal power/ground are considered when analyzing highspeed memory interfaces. This paper assesses how modern tools can be used to address poweraware SI challenges associated with I/O modeling, interconnect modeling, simulation, and analysis.

Quick Start for Signal Integrity Design Using Keysight Advanced Design System (ADS)

A quick overview of how to download and use Signal Integrity Design Using Keysight Advanced Design System (ADS) including examples.

Using ADS for Signal Integrity Optimization

In the beginning there was transient simulation. Ensuring functional chip-to-chip links in a system meant performing a time-domain simulation with a SPICE simulator. The result was a time-domain waveform that was evaluated during post processing for signal integrity (SI). The main task was to measure the eye diagram, usually assuming a perfect clock as the phase reference. Due to rising signaling speeds and decreasing timing margins, the task was made more challenging when it became necessary to account for other effects.

PAM-4 Simulation to Measurement Validation with Commercially Available Software and Hardware

Next-generation of OIF and IEEE signaling standards are seriously considering PAM-4 signaling at 56 Gb/s over electrical channels. To exploit the advantages of PAM-4 signaling, a new measurement and simulation eco-system must be established and validated. Simulation of PAM-4 signals are done with an IBIS-AMI signal generator, an S-parameter channel model, and remote access software for receiver data recovery. Measured data is from commercially available PAM-4 generators, QSFP28 Ethernet cable assemblies, and digital oscilloscope receivers with specialized waveform processing. This paper will present correlation data to validate the software and hardware tools necessary for fast-track deployment in upcoming PAM-4 applications.
