Working with Signal Integrity Analysis Results
The SDF document generated for the configured and run signal integrity analysis comprises one or more tabs that correspond to the nets you have selected for analysis. Each tab contains a chart that can contain multiple wave plots. A wave plot can have multiple waveforms and a waveform represents the simulation data. Accessing signal integrity analysis results. Click the tab at the bottom to…

Configuring and Running a Signal Integrity Analysis
When the design is prepared for a signal integrity analysis as required, configure and run the analysis itself as described on this page. Configuring the SI Setup Options When you select Tools » Signal Integrity and all components have models assigned, the SI Setup Options dialog displays the first time you run this command on an open project. The SI Setup Options dialog Set the track impedance…

Preparing the Design for Signal Integrity Analysis
In order to run a successful Signal Integrity analysis of the design and obtain accurate results, the following has to be performed before running the analysis. Although each net can be screened to provide net and impedance data, not all nets can be analyzed for signal integrity characteristics (voltage and timing). In order to screen successfully for all characteristics, a net must contain at…

Signal Integrity Analysis (by Altium)
Altium Designer includes pre-layout and post-layout Signal Integrity analysis capabilities. Altium Designer's Signal Integrity Analyzer uses sophisticated transmission line calculations and I/O buffer macro-model information as input for simulations. Based on a fast reflection and crosstalk simulator model, the Signal Integrity Analyzer produces accurate simulations using industry-proven…

Signal Integrity Rule Types
The design rules of the Signal Integrity category are described below. The Signal Integrity category of design rules. Signal Stimulus Default Rule: not required This rule specifies the characteristics of the stimulus signal used when performing a signal integrity analysis on the design. This is the signal that is injected at each output pin on the net under test. The worst-case result is returned…

SI Analyzer by Keysight
More and more modern electronic devices incorporate high-speed PCB designs, and signal speeds grow as the technologies evolve (17 GHz in DDR6, 400 Gbps in QSFP++, etc.). Ensuring signal integrity (SI) is a crucial step in the high-speed design. Failure to meet the requirements of the interface developer is very likely to cause problems in further design stages, manufacturing, and performance. To…
