How to Perform Signal Integrity Analysis with HyperLynx
Signal integrity (SI) is a set of measures of the quality of an electrical signal in digital electronics. It involves analyzing and mitigating the effects of noise, distortion, and loss that can degrade the signal as it travels through interconnects such as wires, pads, vias, and components. SI is important for high-speed systems design and compliance analysis.
HyperLynx is a software tool from Siemens that helps designers perform SI analysis for various applications such as SerDes channels, DDRx memory interfaces, and general-purpose SI. HyperLynx SI provides automated flows, detailed reports and waveforms, and interactive simulation that document the design's operating voltage and timing margins. HyperLynx SI also supports standards-based design and compliance analysis for various protocols and technologies. [^1^] [^2^]

How to Perform Signal Integrity Analysis with HyperLynx
Signal integrity (SI) is a crucial aspect of designing high-speed digital systems that can operate reliably and efficiently. SI involves ensuring that the electrical signals that carry binary values are not distorted or corrupted by various factors such as noise, crosstalk, impedance mismatch, and signal loss.

One of the popular tools for performing SI analysis is HyperLynx from Siemens. HyperLynx SI offers a comprehensive solution for pre- and post-layout verification of SerDes channels, DDRx memory interfaces, and general-purpose SI. It also supports standards-based design and compliance analysis for various protocols and technologies.
In this article, we will show you how to use HyperLynx SI to perform some common SI tasks such as interactive simulation, batch simulation, termination analysis, stackup design, crosstalk analysis, and compliance analysis.
Interactive Simulation for Quick Design and Debugging
HyperLynx SI allows you to perform interactive simulation for quick design and debugging of your PCB layout. You can launch HyperLynx SI from your schematic or layout tool and select the nets or components you want to analyze. You can then view the waveforms of the signals on a virtual oscilloscope or logic analyzer. You can also modify the parameters of the components or interconnects and see how they affect the signal quality and timing.
Batch Simulation and Termination Analysis
HyperLynx SI also allows you to perform batch simulation and termination analysis for multiple nets or groups of nets at once. This can help you ensure that all your signals meet the required specifications for signal quality and timing. You can use the General Batch Wizard or the DDRx Batch Wizard to set up your simulation parameters and run the analysis. You can then view the results in a tabular or graphical format.
Stackup Design
HyperLynx SI also helps you design your stackup for optimal SI performance. You can use the Stackup Editor to define your layer structure, material properties, trace width and spacing, impedance targets, etc. You can also import your stackup from your layout tool or use a predefined template. HyperLynx SI will then calculate the impedance values for your traces and show you how they match your targets.
Crosstalk Analysis
HyperLynx SI also helps you analyze and reduce crosstalk in your PCB layout. Crosstalk is the unwanted coupling of signals between adjacent traces or vias that can cause interference or errors. HyperLynx SI allows you to set a coupling threshold, select a victim net of interest, then see which nets are considered coupled in real-time. You can then view the crosstalk waveforms on a virtual oscilloscope or logic analyzer.
Compliance Analysis
HyperLynx SI also helps you perform compliance analysis for various protocols and technologies such as PCI Express, USB, HDMI, Ethernet, etc. Compliance analysis ensures that your design meets the specific requirements for signal quality and timing defined by the standards bodies. HyperLynx SI provides predefined templates for different protocols that guide you through the analysis process step by step. You can then view detailed reports that document your design's compliance status.
Conclusion
HyperLynx SI is a powerful and accessible tool that can help you perform signal integrity analysis for 29c81ba772
